How to Use the PTO Accrual Calculator

Enter your annual PTO allotment and pay frequency, and the calculator shows the per-period accrual rate along with the estimated accrued balance at any point in the year — useful for planning time off against an actual accrued balance rather than the full nominal annual allotment.

The PTO Accrual Calculator projects the gradual buildup of paid time off — here's what to enter.

Entering annual allotment and pay frequency

Enter the total annual PTO allotment and how often you're paid — the calculator computes the per-period accrual rate and can project the accrued balance at any specific point through the year.

Checking the balance before planning time off

As covered in the accrual guide, checking the actual projected accrued balance for a specific future date (rather than assuming the full annual allotment is available) avoids planning time off that exceeds what will actually be accrued by that point.

Frequently asked questions

Does this calculator account for a carryover cap?

Check whether the specific tool supports entering a carryover limit — if not, manually capping a projected multi-year balance at the known policy limit gives a more accurate result than assuming unlimited accumulation.

Can I use this to check my balance against an official HR figure?

Yes — running the calculation and comparing it against the HR system's stated balance is a reasonable check, though as covered in the balance-mismatch guide, minor differences from timing or rounding are normal and not necessarily an error.
