Premium bid break-even calculator

See the highest premium that still leaves room for your goal.

A premium can consume your return before a certificate ever redeems. Use conservative assumptions and include every cost you expect to carry.

Your assumptions

Use cautious inputs. You can change every number.

Confirm the current sale terms first. A calculator cannot verify the sale, clear title, value a property, or predict redemption.

1. Verify the structure.
Use the correct tool only after confirming whether the sale uses a bid-down rate, premium, interest, or penalty.
2. Reserve real costs.
Include registration, recording, research, later taxes, notices, legal guidance, and contingency cash.
3. Keep a hard stop.
If the deal only works in the best case, lower the bid or walk away.
