Mercury pricing (2026)

Last updated October 2026

Mercury has become one of the most widely used banking platforms among startups and small businesses, with over 200,000 companies on the platform. The pricing structure is straightforward: a generous free tier, a mid-range plan for growing teams, and a premium tier for companies with more complex financial operations.

This page breaks down what you get at each level, where the costs add up, and how Mercury compares to alternatives like Brex.

If you are looking for a broader look at Mercury as a platform, see our full Mercury review. For a head-to-head with its closest competitor, see Mercury vs Brex.

Mercury pricing overview

Mercury offers three main pricing tiers, all of which include unlimited users at no additional per-seat cost. This is one of the more notable aspects of Mercury's pricing model: your bill does not increase as your team grows.

The three tiers at a glance

Mercury (free) costs nothing per month. It includes business checking, company cards, expense management, bill pay, basic invoicing, and accounting integrations. For many early-stage startups, this is more than enough. The free tier also grants access to Mercury Treasury once your balance reaches $250,000.

Mercury Plus is priced at $29.90 per month, or roughly $23.90 per month when billed annually (a 15% discount). This tier adds invoicing with ACH debit collection, recurring invoices, unlimited 1099 tax filings, and priority support. It suits businesses that have started sending invoices regularly and want tighter financial workflows.

Mercury Pro costs $299 per month, or approximately $254 per month on an annual plan. Pro includes everything in Plus, along with a dedicated relationship manager, free ACH debit on invoices (rather than the $1 per transaction charge on Plus), NetSuite categorisations, and unlimited invoice volume through the API. This tier is built for companies running complex operations across multiple entities or with high-volume accounts payable.

Flat pricing, not per-seat

Mercury charges per company, not per user. Whether you have 3 employees or 300, the monthly cost stays the same. This stands in sharp contrast to platforms like Brex, where paid plans charge per user and costs can escalate quickly at scale. For a 50-person team, Mercury Plus costs $287 per year. Brex Premium, at $12 per user per month, would cost $7,200 per year for the same headcount.

Mercury free tier

What you get for nothing

The free tier is remarkably complete for a zero-cost plan. Mercury provides FDIC-insured business checking with no monthly fees, no account minimums, and no overdraft charges. You get unlimited physical and virtual corporate cards, free domestic wire transfers, and free international USD wire transfers.

Banking essentials are fully covered. You can send and receive ACH transfers, pay bills, manage expenses, and connect to QuickBooks or Xero without paying a penny. The web and mobile apps are clean and well-designed, which is part of why Mercury has attracted the startup audience it has.

Cards and spending

Company cards come with every account. Mercury issues both physical and virtual debit and credit cards at no charge. The IO card, Mercury's credit card offering, carries no annual fee and no foreign transaction fees, with 1.5% cashback on all spending. Virtual cards can be created instantly for one-time purchases or recurring subscriptions, which is useful for managing software spend.

Accounting integrations

QuickBooks and Xero sync automatically on the free plan. Transaction data flows into your accounting software without manual entry. This alone saves hours of bookkeeping each month. For more advanced integrations, such as NetSuite, you will need to upgrade to Pro.

Who the free tier suits

The free plan works well for pre-revenue startups, bootstrapped businesses, solo founders, and small teams that do not yet need invoicing or advanced financial workflows. If your primary banking needs are receiving payments, paying vendors, and tracking expenses, the free tier covers all of it. You can read more about setting up your account in our guide on how to set up a business bank account.

Mercury Plus

The mid-tier for growing businesses

Mercury Plus sits at $29.90 per month (or about $23.90 per month billed annually) and adds the tools that growing businesses tend to need once they start billing clients and managing a larger volume of transactions.

Invoicing capabilities

Invoicing with ACH debit is the headline feature. On the free plan, you can create and send invoices, but collecting payment via ACH debit requires Plus. Each ACH debit transaction costs $1. You can also set up recurring invoices, which is useful for retainer-based businesses, subscription models, or regular client billing. The invoicing API supports up to 500 invoices per month, which is more than sufficient for most growing companies.

Reimbursements and tax filings

Reimbursements are included for up to 20 active users per month. Additional users beyond 20 cost $5 each per month. This makes Plus practical for companies that need to reimburse employees for expenses but do not yet have the volume to justify Pro. Unlimited 1099 tax filings are also included, removing a cost that can add up at year-end for businesses with many contractors.

Additional perks

Mercury throws in a few partner discounts. Plus subscribers receive $50 off eligible LegalZoom Compliance Plans and six months of free access to Xero. These are modest savings, but they add up for early-stage companies managing tight budgets.

Who Mercury Plus suits

Plus is the right plan for businesses that have moved past the earliest stages and are now invoicing clients, managing a small team's expenses, or filing 1099s for multiple contractors. The $29.90 monthly cost is easy to justify once you are sending more than a handful of invoices per month.

Mercury Pro

The premium tier for complex operations

Mercury Pro is priced at $299 per month ($254 per month billed annually) and is designed for companies with more sophisticated financial operations. The jump in price from Plus to Pro is significant, so it is worth understanding what that additional spend buys you.

Relationship manager

A dedicated relationship manager is Pro's most valuable feature. Rather than navigating support tickets, Pro customers get a named contact who understands their business and can help with account questions, troubleshooting, and strategic advice. For companies managing large balances or complex treasury needs, this level of support can save considerable time and frustration.

Enhanced invoicing

ACH debit on invoices is free at the Pro level. Where Plus charges $1 per ACH debit transaction, Pro removes that fee entirely. The invoicing API also lifts the 500-invoice cap, allowing unlimited invoice creation. For high-volume invoicing operations, the savings on per-transaction fees alone can offset a meaningful portion of the monthly cost.

Reimbursements at scale

Pro supports up to 250 active reimbursement users per month, compared to 20 on Plus. Additional users beyond 250 are charged at $5 each. This makes Pro the obvious choice for companies with larger teams that regularly submit expenses.

NetSuite and advanced integrations

NetSuite categorisations are exclusive to Pro. If your finance team uses NetSuite as its ERP, Pro allows transaction data to flow into NetSuite with enriched categorisation, reducing manual reconciliation work. This is a niche feature, but for companies that need it, there is no workaround on lower tiers.

Who Mercury Pro suits

Pro makes sense for Series A and beyond startups with 50 or more employees, companies processing high volumes of invoices with ACH debit collection, teams with complex accounting setups that require NetSuite integration, and businesses that value having a dedicated banking relationship. It is also worth considering if your monthly ACH debit transaction fees on Plus regularly exceed $250, as the free transactions on Pro would offset the price difference.

Mercury Treasury

Earning yield on idle cash

Mercury Treasury lets you put idle cash to work by sweeping funds into investment vehicles that aim to deliver higher returns than a traditional savings account. As of April 2026, Mercury Treasury was offering approximately 4.65% APY, though yields fluctuate and are not guaranteed.

How Treasury works

Funds are invested across two options, and you control the split. Mercury offers a State Street Institutional U.S. Government Money Market Fund (ticker: MRGXX) and a Morgan Stanley Ultra-Short Strategy Portfolio (ticker: MCRYX). You can allocate your funds between these two options in 10% increments. The money market fund invests at least 99.5% of its assets in cash, U.S. government securities, and repurchase agreements. The ultra-short fund holds commercial paper, certificates of deposit, and other short-term instruments.

Liquidity is reasonable but not instant. Withdrawals from the money market fund take 0 to 1 business days, with same-day withdrawals available if requested before 3pm ET. The ultra-short fund takes 1 to 2 business days. Mercury also supports automatic twice-monthly transfers between your checking and Treasury accounts.

Eligibility and fees

Treasury access requires a $250,000 Mercury balance on the free tier. This threshold is waived for Plus and Pro subscribers in some cases, though Mercury's documentation is not entirely clear on this point. Treasury is not FDIC-insured, as it involves investment products rather than bank deposits. There is a management fee, though the specific rate is calculated according to a separate fee schedule that Mercury does not prominently display. It is worth asking about this before transferring large sums.

Extended FDIC coverage

Mercury offers expanded FDIC coverage of up to $3 million through its sweep network for balances above the standard $250,000 FDIC insurance limit. This is a meaningful benefit for startups holding significant cash reserves. The sweep network distributes funds across multiple partner banks to stay within FDIC limits at each institution.

Mercury Venture Debt

Funding through Mercury Raise

Mercury has expanded beyond banking into lending with Mercury Raise, its venture debt product. Details on Mercury Raise are limited in public documentation, and specific terms, interest rates, and eligibility criteria are not published on Mercury's website. The product is designed to complement Mercury's banking platform, allowing startups to access capital without leaving the Mercury ecosystem.

What we know

Mercury Raise appears to target startups that already bank with Mercury. Having your financial data on the platform gives Mercury visibility into your cash flow and runway, which likely informs underwriting decisions. This is a similar approach to what other fintech lenders use: the banking relationship doubles as an underwriting advantage.

Terms and rates are not publicly available. If venture debt is relevant to your business, you will need to speak with Mercury's team directly. It is worth comparing any offer against standalone venture debt providers to ensure competitive terms.

Hidden costs and fees

Where the costs live

Mercury's headline pricing is clean, but there are a few costs that do not appear on the main pricing page. Understanding these before you commit helps avoid surprises.

Wire transfer fees

Domestic wires are free. This is unusual in business banking and represents a genuine saving over traditional banks, which typically charge $15 to $50 per outgoing wire. International USD wires are also free, though you can opt to pay $15 to cover the recipient's incoming wire fee (a "charges borne by sender" option).

Foreign exchange costs

Non-USD international transfers carry a 1% FX fee. If your business regularly pays overseas contractors or suppliers in local currencies, this cost can add up. A $50,000 payment in euros, for example, would incur a $500 fee. For high-volume international payments in non-USD currencies, it is worth comparing Mercury's FX rates against dedicated services like Wise or Airwallex.

ACH fees

Outgoing ACH transfers are free for most accounts. Some sources suggest that accounts below $250,000 in balance may be limited to 10 free outgoing ACH transfers per month, with a $1 fee for each additional transfer. Mercury's documentation is inconsistent on this point, so it is worth confirming with their team if your business sends a high volume of ACH payments.

Mercury Books

Mercury Books, the platform's built-in bookkeeping tool, costs $35 per month. Mercury is currently waiving this fee until 31 December 2026, so there is no cost for the time being. After that date, it will add $420 per year to your Mercury spend. Books is optional, and most businesses using external accounting software will not need it.

Mercury Personal

Mercury Personal accounts cost $240 per year as a standalone product. However, if you hold an active Mercury business account in good standing, Mercury Personal is included at no extra cost. This is a nice perk for founders who want to keep personal and business banking on the same platform.

Mercury vs Brex pricing comparison

Two different pricing models

Mercury and Brex take fundamentally different approaches to pricing. Mercury charges a flat fee per company regardless of team size. Brex charges per user on its paid plans. This distinction has significant cost implications as your team grows.

Plan-by-plan comparison

At the free level, both platforms offer a $0 option. Mercury's free tier includes full banking, cards, and basic financial tools. Brex Essentials is also free but focuses on corporate cards, bill pay, and reimbursements rather than banking. Brex does not offer its own bank accounts in the same way Mercury does. The two platforms serve somewhat different primary functions: Mercury is a bank first, while Brex is a spend management platform first.

Mercury Plus ($29.90 per month) vs Brex Premium ($12 per user per month). For a team of two, costs are comparable. By the time you reach five users, Brex Premium costs $720 per year while Mercury Plus costs $287. At 25 users, Brex Premium reaches $3,600 per year. At 100 users, it hits $14,400. Mercury Plus stays at $287 regardless.

Mercury Pro ($299 per month) vs Brex Enterprise (custom pricing). Mercury Pro's annual cost of roughly $3,050 is fixed. Brex Enterprise requires a conversation with their sales team and pricing varies. For larger teams, Brex's per-user model can become considerably more expensive than Mercury's flat rate.

Feature differences worth noting

Brex has stronger spend management tools. Dynamic approval chains, AI compliance detection, and multi-entity support are more developed on Brex. If your primary need is controlling and categorising employee spending across a large team, Brex may be the better fit regardless of cost.

Mercury has stronger banking features. Free wires, Treasury, and a more traditional banking experience give Mercury an edge for companies that want a primary business bank account. Brex is not a bank and does not offer the same deposit and lending products.

Some companies use both. It is not uncommon for startups to bank with Mercury and manage corporate card spending through Brex, using each platform for what it does best. For a deeper comparison, see our Mercury vs Brex analysis, and for Brex's costs in detail, see Brex pricing.

Who Mercury is best for

The ideal Mercury customer

Mercury has found its strongest product-market fit with technology startups, but the platform works well for a broader range of businesses than its branding might suggest.

Pre-seed and seed-stage startups

Mercury's free tier is one of the best banking options for early-stage companies. No monthly fees, no minimum balance, free wires, and a clean interface make it easy to open an account during incorporation and start operating without thinking about banking costs. The lack of a physical branch network is rarely a limitation for technology companies.

Series A through Series C companies

Growing startups benefit from Mercury's flat pricing and Treasury product. As your team and cash reserves grow, Mercury's per-company pricing keeps costs predictable, and Treasury lets you earn yield on money that would otherwise sit idle. The Plus and Pro tiers add the financial workflow tools that finance teams need at this stage.

Bootstrapped and profitable small businesses

Mercury works well for established small businesses, not just venture-backed startups. Free banking, no minimum balance, and solid accounting integrations make it a practical choice for any small business comfortable with digital-only banking.

Who should look elsewhere

Companies that need physical branch access will find Mercury's digital-only model limiting. Businesses with heavy international payment volumes in non-USD currencies may find the 1% FX fee expensive compared to specialist providers. And companies whose primary need is corporate card and expense management, rather than banking, may find Brex or Ramp a better primary platform. Our guide to the best business bank accounts for startups covers more alternatives.

Is Mercury worth it?

The free tier is a clear yes

For early-stage companies, there is little reason not to open a Mercury account. The free tier is competitive with or superior to most paid business banking products from traditional banks. Free domestic and international wires alone save hundreds or thousands of dollars per year compared to legacy banks.

Plus pays for itself quickly

At $29.90 per month, Mercury Plus is easy to justify for any business that regularly invoices clients. The unlimited 1099 filings save time and money at tax season, and priority support means faster responses when issues arise. The annual cost of roughly $287 is modest by any measure.

Pro requires a cost-benefit calculation

Mercury Pro at $299 per month is a more considered decision. The relationship manager and free ACH debit on invoices are valuable, but you need sufficient transaction volume for the savings to offset the cost. If you process fewer than 250 ACH debit invoices per month, the per-transaction savings over Plus do not cover the price difference. The NetSuite integration and expanded reimbursement capacity are the features most likely to tip the decision for finance teams at larger companies.

Treasury adds meaningful value

For companies holding $250,000 or more in cash, Treasury is where Mercury delivers outsized value. At roughly 4.65% APY, $1 million in idle cash would generate approximately $46,500 in annual yield. Even after management fees, this is significantly better than the near-zero interest rates offered by most business checking accounts. The combination of free banking and competitive treasury yields makes Mercury's total value proposition stronger than its pricing page alone might suggest.

Managing your finances alongside Mercury

Mercury handles banking and payments well, but the documents that surround your financial operations (contracts, tax filings, incorporation papers, investor agreements) need a home too. Fabric works well as a companion to Mercury for storing and organising financial records. Its cloud drive keeps documents accessible and searchable at $8 per month on an annual plan, which is a practical addition to a Mercury-centred financial stack. You can learn more about Fabric's approach at fabric.so/info/environment.

Keeping your financial documents organised alongside your banking platform saves time during tax season, due diligence, and audits. Rather than hunting through email attachments and shared drives, having a single place for contracts, receipts, and statements means your finance team can find what they need without friction.
