About BiWeeklyCalc

BiWeeklyCalc is a collection of browser-based tools for understanding recurring payments, pay schedules and savings goals. You can compare a loan, plan a paycheck or work backward from a target without creating an account.

How estimates are built

Each calculator describes its formulas and simplifying assumptions on the same page. Payment schedules apply periodic interest before the payment and cap the final payment at the amount outstanding. Figures are calculated at full precision and displayed to two decimal places, so displayed rows can have small rounding differences.

Scope

We do not calculate local taxes, recommend loan providers or claim that a model matches every financial contract. Confirm loan terms and actual payroll dates with the relevant provider.
