Periods until planned leave
Provide the periods until planned leave used for this specific estimate. Use the same period and unit as the other inputs.
Planned PTO use
Provide the planned pto use used for this specific estimate. Use the same period and unit as the other inputs.
Projected balance before leave
Provide the projected balance before leave used for this specific estimate. Use the same period and unit as the other inputs.

How this calculator works
Projected balance = current balance + future accrual − planned use.
Worked example
32 current hours plus five periods at 4 hours gives 52; using 40 leaves 12 hours.
How to interpret the result
Use the displayed result as a planning figure, not as an official payroll determination. A materially unexpected result usually means the entered period, rate, threshold, break, accrual rule, or conversion basis should be checked.
Rounding policy
Hours and percentages
Outputs are rounded to two decimal places; money is rounded to the nearest cent.
Assumptions and limitations
- All policy rates and balances are entered by the user.
- Results are planning estimates and do not establish a legal leave entitlement.
Frequently asked questions
Does this calculator know my employer policy?
No. Enter the rates, caps and balances from your handbook, agreement or payroll record.
Is this legal or payroll advice?
No. Verify eligibility, carryover, payout and protected-leave rules with the appropriate employer records or professional guidance.
When should I recalculate with the PTO Usage Forecast Calculator?
Recalculate whenever the hours, rates, schedule, pay period, policy assumptions, or planned usage changes. Saving the exact inputs makes comparisons more reliable.
How accurate is the PTO Usage Forecast Calculator?
The arithmetic follows the formula shown on the page. Real payroll or policy outcomes can still differ because of contracts, jurisdictional rules, employer systems, taxes, deductions, caps, and rounding practices.
