The statutory ceiling
This is the maximum. Bidders compete by bidding the rate down at the sale, so the rate you actually earn is set at the auction and is often lower. The minimum on redemption is 5%, except for a certificate bid at 0%.
The minimum you can earn
On redemption, interest is the greater of the interest accrued at the bid rate or an absolute 5% of the face amount. Florida law excludes certificate interest and this minimum during the first 60 days after delinquency, apart from the separate pre-sale charge. A certificate bid down to 0% is the exception. It is carved out of the minimum by statute and earns nothing, which is why bidders accept 0%: they are buying the path to a deed, not a yield.
How interest accrues
The annual bid rate is calculated monthly from the first day of each month. At redemption, F.S. 197.472(2) applies accrued interest or an absolute 5 percent of the face amount, whichever is greater, except for zero-percent bids. The minimum is not an annual rate. F.S. 197.172(2) bars certificate interest and that minimum during the first 60 days after delinquency, except for the separate pre-sale charge.
Why some certificates are bid to zero
A zero-percent bid earns no interest and is exempt from the mandatory 5 percent minimum at redemption. Holding a certificate can permit an eligible deed application after the waiting period; it does not guarantee ownership.
The headline figure is a ceiling, not a forecast. To see what a certificate actually pays after the rate is bid down, run the numbers in the yield calculator, and compare Florida against other states on interest rates by state.

Worked certificate scenarios
Each scenario starts with a fictional $5,000 certificate. Months mean months charged for interest. Confirm the calendar count with the county office; this tool accepts a month count and does not calculate it from dates.
| Scenario | Bid rate | Charged months | Interest | Total with principal | Annualized gross yield |
|---|---|---|---|---|---|
| Four charged months | 8% | 4 | $250.00 | $5,250.00 | 15% |
| Twelve charged months | 8% | 12 | $400.00 | $5,400.00 | 8% |
| Zero-percent bid | 0% | 4 | $0.00 | $5,000.00 | 0% |
Annualization expresses the modeled interest over a year using charged months. It does not predict repeat purchases or future redemption. The cited state rules above explain the floor and accrual method.
