Quick, honest calculators for the moves that actually shift your payoff date — built on the same engine that powers Debt Engine.
See exactly which debt to pay off first, your debt-free date, and the interest an extra payment saves.
Track your Affirm / Klarna / store-card 0% promos and the retroactive interest you'll owe if you miss the date.
Find the two 'extra' paychecks a year biweekly earners get — and the firepower hiding in them.
Compare a 0% intro APR offer against your current card, including fees, payoff time, and approval odds.
Compare a refinance offer against your current loan, including payment relief, fees, payoff time, and total cost.
The tools answer one question once. Debt Engine tracks every debt, watches your deadlines, and runs the windfall mechanic month after month — through debt payoff, into wealth-building, all the way to an early-retirement plan.
