Plain math. Plain English. Free.

Built for high-stakes money decisions

Compare the deal, not just the headline rate.

PlainFigure turns mortgage offers, refinance options, debt payoff plans, and retirement assumptions into decision briefs: the cost spread, the tradeoffs, the questions to ask, and the next action. Calculators run in your browser and show their assumptions.
