LoanClarityPayoff planner, fully offline
About
LoanClarity is a fast, fully offline loan calculator for anyone comparing a mortgage, auto loan, or personal loan before signing. Enter the amount, rate, and term to see your monthly payment, total interest, and payoff date instantly — no ads, no account, no waiting on a server.
What makes LoanClarity different is the What-If slider: drag it to add an extra monthly payment and watch the interest saved and payoff date update live, so you can see exactly how much sooner you could be debt-free. Save multiple scenarios — refinance vs. keep, 15-year vs. 30-year, 100 vs. 200 extra a month — and compare them side by side.
