About The Ledger

A small set of everyday calculators, built to be fast and to respect your time.

The Ledger is a free collection of calculators for the sums people look up most often — Zakat, loan repayments, percentages and age. Every calculation runs in your browser; nothing you enter is uploaded, stored or shared.

We keep the tools simple on purpose: no accounts, no clutter, just the number you came for.
