The Short Answer
- Highest headline rateRelay Scale at 3.21% APY, but the plan costs $90 a month.
- Best return on a small balanceFee-free options, because a monthly plan fee can swallow the interest. Ramp's 2% cash account leads at $10K and $25K in the table below.
- Ramp's cash accountRamp lists 2% on cash in an FDIC-insured account on its Free plan.

What You Actually Keep
Net annual return is the balance times the APY, minus twelve months of plan fees. It assumes the rate stays flat for the year, which these variable rates may not. Fees are shown in full, before any waiver.
| Provider and plan | APY | Plan fee | Net a year on $10,000 | Net a year on $25,000 | Net a year on $100,000 |
|---|---|---|---|---|---|
| Relay Starter | 1.19% | $0 | $119 | $298 | $1,190 |
| Relay Grow | 1.87% | $30 a month | -$173 | $108 | $1,510 |
| Relay Scale | 3.21% | $90 a month | -$759 | -$278 | $2,130 |
| Bluevine Standard | 1.3% | $0 | $130 | $325 | $1,300 |
| Bluevine Plus | 1.75% | $30 a month | -$185 | $78 | $1,390 |
| Bluevine Premier | 3% | $95 a month | -$840 | -$390 | $1,860 |
| Ramp Free plan cash account | 2% | $0 | $200 | $500 | $2,000 |
Mercury isn't in this table because its fee page publishes no rate. Best result in each column is bold. Rates are variable and the paid-plan fees are shown before any waiver.

- No plan fee on the Free plan

- Best used with Ramp's other tools
Why the Top Rate Isn't Always the Best Deal
Relay's Scale plan pays 3.21% but costs $1,080 a year. Against the free Starter plan at 1.19%, the extra 2.02 percentage points only pay for themselves once the balance passes roughly $53,500. Below that, the free tier wins.
The same logic applies to Bluevine Premier at 3.0% and $95 a month. Before you upgrade for the rate, work out your usual balance and test it in the table.
Where a Seller's Cash Reserve Belongs
Keep a reserve in an account you can reach the same day. Sellers who run on inventory credit need cash on hand for the month a supplier invoice lands before the payout does. The capital stack framework treats reserve cash as the layer that stops one slow month from forcing you into expensive financing.
Don't chase half a percent at the cost of access. If a transfer takes days to settle, that isn't a reserve.
A Note on Deposit Insurance
None of these fintechs is itself an FDIC-insured bank. They hold deposits at partner banks, and the coverage rules depend on how those deposits are placed. Each provider explains the terms on its own site. Read that page before you move a large balance.

Frequently Asked Questions
Are these rates guaranteed?
No. Every rate on this page is variable and can change at any time. The Relay figures are dated 9/17/2026, and the others were read on the review date. Check the provider's site before you decide.
Do I need a separate savings account at all?
Not if your checking account pays competitive interest. A separate account helps if you want to stop yourself spending a tax or inventory reserve.
Is interest income taxable?
Interest earned by a business is generally taxable income. Ask your accountant how to report it.
