Why the numbers hold up

Schedules balance to the penny

Every amortization schedule reconciles exactly: the principal columns sum to the amount borrowed, and the interest total matches the schedule printed below it. No rounding drift is left for you to find.

Rates cited to who issued them

Brackets, limits and thresholds come from the body that publishes them, the IRS, the SSA, state revenue departments and their overseas equivalents, and each figure carries the source and the year it applies to.

Checked against known answers

Each calculator is tested against worked examples published by regulators and against a financial calculator’s own output, so a wrong answer fails the build rather than reaching the page.
