Frequently asked questions

How is PTO accrual per pay period calculated?

Your annual PTO hours are divided by the number of pay periods in a year: 52 weekly, 26 biweekly, 24 semimonthly or 12 monthly. That accrual rate is multiplied by the periods you have worked.

What are the different PTO accrual methods?

Per-period accrual earns a fixed amount each paycheck and is what this tool models. Other common methods include annual lump-sum (the full balance granted on day one), monthly accrual, and hourly accrual where you earn a set amount per hour worked. Pick the pay frequency that matches your plan to approximate it.

How do you convert PTO hours into days?

This calculator assumes a standard 8-hour work day, so it divides your hours by 8. If your workday differs, divide the accrued hours by your own daily hours instead.

Does carryover and hours used affect the balance?

Yes. Carryover hours are added to what you accrue this year, and hours already taken are subtracted. The balance is accrued plus carryover minus hours used, so it can go negative if you take leave in advance.

Is my PTO data private?

Yes. The calculation runs entirely in your browser. Nothing you enter is stored or sent to a server, so your hours and balances stay on your device.

Is this the official accrual used by my employer?

No. This is an estimate based on straight-line accrual. Company policies can include caps, waiting periods, rounding rules and tenure tiers, so always confirm with your HR team or pay stub.
