Pure math you can run on any number, instantly. Type a number, get an answer - no account, nothing stored.
Some sites lock the basic math behind a login. Ours are free and need no account. And because they share one engine, the numbers never contradict each other.
Each calculator is plain arithmetic that runs the moment you type - no data is fetched, nothing is billed, nothing is stored. The set covers the questions beginners actually ask: loan payoff (the real payment and how it shrinks over time), affordability (the 28/36 check), rent vs. buy, and cash to close.
The important detail: the calculators reuse the very same cost engine that powers the true monthly cost and the afford check. So the closing costs in the calculator match the closing costs on a listing - there's one source of truth, not three slightly different answers.
It's transparent math, free, and consistent everywhere it appears. No login wall, no upsell to see your own numbers, and no surprise where two tools disagree.
