Rho vs Mercury: Which startup bank fits your stage?

Evaluate both the same way: identify the chartered banks holding the deposits and the FDIC structure. Rho checking is held at Webster Bank, a division of Santander Bank, N.A., Member FDIC, insured up to the standard $250K, and Rho savings is eligible for up to $75M in FDIC deposit insurance per depositor through American Deposit Management Co. and its partner banks, subject to FDIC requirements. Mercury deposits are held at Choice Financial Group and Column N.A., Members FDIC, with up to $5M in coverage through their sweep networks. FDIC insurance at either platform protects against the failure of an insured bank holding your deposit; it does not protect against the failure of Rho or Mercury themselves.

It depends on your balance. Rho Business Savings pays up to 1.00% (variable, as of 08/17/2026); withdrawals to checking settle within 2 business days. For larger balances, Rho Treasury opens at $50K and Mercury Treasury at $250K, so between $50K and $250K only Rho offers treasury yield. Both treasury products carry variable rates that change frequently, so compare current rates at rho.co/treasury and mercury.com rather than relying on any static figure. Treasury investments are not FDIC insured at either provider.

Yes. Opening a Rho account takes less than 10 minutes, and Rho's team assists with migration, including moving balances, updating payment rails, and recreating vendor and payroll flows. Most companies run both accounts in parallel for a billing cycle before closing the old one.

Mercury's core tier is free. Paid tiers are Mercury Plus at $35/mo and Mercury Pro at $350/mo, or $29.90 and $299 with annual billing, which is the pricing page's default display (mercury.com/pricing, as of 08/17/2026). Rho has no monthly software fee at any tier.

Mercury pays 1.5% cashback on the IO card. Rho pays 1.25% standard on the Rho Card with Daily Terms (1% on Monthly Terms), and up to 2% with Rho Platinum (terms apply) on up to $1M in eligible annual card spend.

If you want a purely self-serve account for a small, simple operation and do not expect to need phone support or treasury yield below a $250K balance, Mercury's free tier is a fit. If you are starting a company, Rho gets you from incorporation to a bank account in one flow, with phone support and Treasury from $50K from day one.
