Find two figures from the same period
You need PTO earned and eligible hours for the same accrual period. The leave balance alone is not enough. A balance can include unused leave from earlier periods, carryover, adjustments and deductions. If accrual is posted on a different date from the payday, match the underlying periods first.
Worked example: one PTO hour per 30 eligible hours
Suppose a statement records 75 eligible hours and 2.5 PTO hours earned. Divide earned leave by eligible hours: 2.5 ÷ 75 = 0.033333… . This is the observed hourly factor. Divide eligible hours by earned leave to express the same rate as one PTO hour for every 30 eligible hours. At an unchanged rate, 120 future eligible hours would earn 4 PTO hours before caps and rounding.
Why two statements may suggest different rates
Imagine the actual accrual is 80 annual PTO hours spread across 26 postings. Each posting is about 3.076923 hours, but a statement might display 3.08. Inferring the policy from that displayed value introduces rounding error. A balance cap can also reduce a posting, making a correct policy look like a lower hourly rate.
Another possibility is a fixed-per-period policy. When the same leave amount posts after both a 72-hour and an 80-hour period, dividing by worked hours produces different ratios even though the policy never changed. Identify the accrual method before comparing ratios.
Prepare a useful payroll question
Collect the accrual dates, earned amounts, eligible hours and policy wording. Ask which hours are eligible, whether the rate changed and whether a cap or waiting period applied. A specific discrepancy is easier to investigate than a claim based on the ending balance.
Use the balance reconciliation guide for missing transactions and biweekly PTO accrual for fixed postings. The US Department of Labor’s leave overview explains the limited role of the FLSA in leave benefits; applicable policies and other requirements still need checking.
Frequently asked questions
How do I find the PTO rate from my pay stub?
Divide PTO earned during a period by the eligible hours in that same period. Use earned PTO, not the ending balance, and confirm which hours the policy includes.
What does one hour per 30 hours worked mean?
The accrual factor is 1 ÷ 30, or approximately 0.033333 PTO hours per eligible hour. At that factor, 75 eligible hours earn 2.5 PTO hours before policy limits.
Why does the calculated rate differ between paychecks?
Rounded postings, rate changes, a balance cap, ineligible hours or fixed-per-period accrual can change the apparent rate. A pay-stub ratio alone cannot identify the cause.
Can I enter zero PTO earned?
This tool requires a positive earned amount to calculate an hours-per-PTO-hour ratio. Zero earned may reflect a waiting period, cap or non-accruing policy; check the policy instead of inferring a rate.
