About HourLedger

HourLedger is a set of free work-hours and overtime calculators built and maintained by an independent software developer — no company, no sales team, no sign-up wall. It's being built in public: features ship small, often, and with their working shown.

It started with a simple observation: most timesheet calculators online either get the overtime rules subtly wrong, bury the answer under ads, or quietly upload your hours to someone's server. Pay calculations deserve better defaults than that.

How it's built

Every pay rule is tested. The federal 40-hour rule, California's daily overtime and double-time thresholds, the 7th-day rule, rounding policies, overnight shifts — each is covered by an automated test suite that runs before every release. If a rule changes or a bug is found, a test is written first.

Your data stays yours. The calculators run entirely in your browser. Entries are saved to your device's localStorage so they survive a refresh, and nothing is ever transmitted to a server. There is no account, because there is nothing to put in one.

It stays free. Every calculator is free to use without limits. If the site ever carries advertising to cover its costs, that will never gate the calculators or change how your data is handled — see the privacy policy.

What it is — and isn't

HourLedger gives you accurate arithmetic under standard non-exempt pay rules, with the rules cited to their official sources on each calculator page. It is general information, not legal or payroll advice: exemptions, alternative workweek schedules, and local ordinances can change the math. When pay is in dispute, verify with your state labor agency or a qualified professional.
