Direct answer
Subtract 16 PTO hours from the available balance, then add only accrual that should happen before the time off starts.
Projected accrual matters only if it is available before the request is taken.
Use this answer for subtracting a small PTO request from an existing balance. Before relying on it, compare the inputs with your HR portal, PTO policy, company calendar, handbook, manager guidance, or employment agreement.
Open PTO CalculatorFormula and worked example
Formula: Projected PTO balance = current balance + eligible accrual - 16 hours.
Example: If you have 42 hours and no new accrual before the request, using 16 hours leaves 26 hours.
Keep the formula and example beside the calculator result. That makes it easier to see whether the difference came from hours, dates, pay frequency, or policy wording.

Step-by-step method
Key checks
- Write down the PTO balance, accrual timing, daily hours, date range, holidays, notice period, and approval rules before calculating.
- Calculate the plain version first so the baseline is visible.
- Apply the rule: Projected PTO balance = current balance + eligible accrual - 16 hours.
- Adjust for partial days, holidays, blackout dates, projected accrual, custom schedules, payout rules, and business-day wording only when those details apply.
- Compare the result with your HR portal, PTO policy, company calendar, handbook, manager guidance, or employment agreement before using it for a real PTO request, resignation plan, deadline estimate, final-pay note, or workplace planning decision.
What can change the answer
The answer can change when partial days, holidays, blackout dates, projected accrual, custom schedules, payout rules, and business-day wording are part of the real situation.
That does not make the calculator unreliable. It means the inputs need to match the real rule, schedule, paycheck, or policy record.
If the result affects pay, PTO, notice timing, or a formal deadline, treat it as a planning estimate until the official source confirms it.
Common mistakes
Key checks
- Do not add future accrual that arrives after the PTO date.
- Do not convert 16 hours into days without checking hours per day.
- Do not ignore minimum balance or negative balance rules.
