Project a PTO balance from current hours, accrual per pay period, future periods, planned leave and an optional balance cap. Current balance, accrual and planned leave all use hours. A day of leave is not necessarily eight hours; convert using the work schedule and policy that apply to you. If the leave record uses days, confirm how partial days and varied shifts are counted before making a conversion. The calculator does not infer an employee’s daily hours or apply an assumed workweek. A balance projection is only meaningful when every input uses the same policy unit.
How to use it
- 1
Enter current PTO hours, accrual hours per pay period and the whole-number count of future periods.
- 2
Enter planned leave in hours and a balance cap, or zero for no cap. The cap applies at projection before leave.
- 3
Click Calculate result to submit the inputs. Editing fields keeps the last submitted output until you click again.
- 4
Check the worked example, units and method limits before using the result.
Formula and methodology
Accrued hours = rate × future pay periods. Projected pre-leave balance = min(current + accrual, cap) when a cap is entered. Post-leave balance = pre-leave balance − planned leave.
The calculator applies the displayed arithmetic to the values entered on this device. It does not silently load a local tax rate, currency conversion or commercial assumption.
Worked calculation example
40 current hours plus four hours for each of six periods gives 64 hours before leave. Taking 16 hours leaves 48 hours when the cap is 80.
How to interpret your result
Fixed-rate projection with a cap applied before all planned leave. No dated ledger, carryover expiry, legal entitlement, employer approval or changing accrual rates. The examples identify the method and input basis, so the result can be checked without guessing a hidden convention.

Scenario comparison
| Scenario | What it shows |
|---|---|
| 40 current hours + 4×6 accrual − 16 leave | 48 hours. |
| Same inputs with cap 50 | 34 hours after leave. |
| Planned leave 70 with a 64-hour pre-leave balance | six hours short. |
Common mistakes to avoid
- Treating six pay periods as six months.
- Assuming a universal eight-hour leave day.
- Applying the projection’s cap timing to a different employer policy.
Substitute the same inputs into the disclosed equation and compare with this example: 40 current hours plus four hours for each of six periods gives 64 hours before leave. Taking 16 hours leaves 48 hours when the cap is 80. Keep the method, units and source assumptions with any recorded result.

Accrual per pay period
Enter the rate earned in one eligible pay period and a whole-number count of future periods. Weekly, fortnightly, twice-monthly and monthly schedules have different counts. Six periods does not automatically mean six months. The tool assumes a fixed accrual rate for all entered periods. Eligibility rules, tenure-based rate changes, unpaid leave and prorated periods require additional accounting. Verify the rate against the employer’s policy and a current balance record.
Cap at the projection point
An optional positive cap limits the projected balance before planned leave is subtracted; zero means no cap in this simplified calculation. This is a cap-at-projection model, not a chronological leave ledger. If leave occurs partway through the period and allows more accrual before a cap is reached, the real result can differ. Expiry dates, carryover resets and caps applied differently to existing balances are also outside this formula. The page discloses the timing convention rather than silently choosing an employer’s policy.
Planned leave and approval
A negative projected balance identifies a shortfall under the entered assumptions. It does not approve borrowing leave, classify absence or establish a legal entitlement. The shortfall output shows the additional hours needed to cover the planned leave in this model. Employer approval, blackout periods, public holidays and separate sick or parental leave accounts remain distinct questions. Use the projection as a discussion aid and reconcile it with the official leave system before booking consequential plans.
Privacy and browser processing
Values entered on this page are processed in the current browser session. SolvePilot does not require an account and does not receive the values entered into the calculator. Refreshing or closing the page clears the working values unless the browser itself restores a previous session. Avoid entering identifying or account information because the calculation needs summary values only.
Accuracy and verification
Accuracy depends first on input quality. Confirm definitions, scales, dates and source information before entering a value. Keep an independent record of any result used for planning because this page does not create an official statement or retain a calculation history.
Limits of this estimate

Frequently asked questions
How do I calculate accrued time off?＋
Multiply eligible future pay periods by the policy’s accrual hours per period, then add the current balance. Apply a cap only if it actually matches your policy. This page uses the stated cap-at-projection convention and subtracts planned leave afterward.
Can I enter leave in days?＋
Convert it to hours using your actual schedule and policy first. Eight hours per day is not universal. Part-time schedules, compressed weeks and partial-day rules can change that conversion, so keep the employer’s unit definition with your calculation.
What does a negative balance mean?＋
Planned leave exceeds the projected available hours in this simplified model. The supporting shortfall figure gives the gap. It does not determine whether advance leave is allowed or whether the employer will approve the request.
Will this handle leave taken before the cap is reached?＋
Not as a dated ledger. It projects accrual, applies the entered cap and then subtracts all planned leave. A different sequence can allow additional accrual, so use an actual period-by-period leave record when timing affects the cap.
Does it calculate a legal leave entitlement?＋
No. It applies the rate and balance rules you provide. Employment law, contract terms, eligibility and leave categories vary. The official policy and relevant local requirements are authoritative, and this calculator does not supply them automatically.
