We read everything. Corrections get priority; calculator requests shape what we build next.

Reporting an error

Include the calculator name, the inputs you used (the Share link is perfect), the result you got, and what you expected. If you have a source for the correct figure, link it.

Requesting a calculator

Tell us the question you’re trying to answer, not just the calculator name. “Should I refinance from 7.1% to 6.2% if closing costs are $4,000?” is more useful than “refinance calculator”.
