SIX CALCULATIONS, ONE STATEMENT
Recurring savings calculator — project your monthly contributions
Model simple interest, compound growth, a loan's monthly repayment, a recurring savings plan, a credit card payoff or a multi-debt strategy — then read the result the way your bank or payroll department would print it, penny for penny.
Recurring savings
A starting balance plus a fixed contribution each month — the way a payroll savings deduction, pension top-up or recurring deposit grows.
Depositing at the start of each month earns one extra month of interest on every contribution over the term.
Full breakdown
Every period, principal-versus-interest split and running balance — the same shape as an amortization table from a bank.
Why the number should match your statement
Per-period rounding, not end rounding
Interest and principal are rounded to the cent on every single period, exactly as a bank's ledger does — not calculated in full precision and rounded once at the end, which is where most quick calculators drift from a real statement.
Real-world day-count rules
Simple interest supports both actual/365 and actual/360 conventions. Loans use standard reducing-balance monthly compounding. These are the same conventions written into most consumer credit agreements.
Every formula, shown in the open
No black box. The methodology panel below spells out exactly which formula ran, with your own numbers substituted in, so you can check it line by line against a payslip or bank letter.
