Vacation Accrual Estimate

Estimate earned vacation hours, used vacation, available vacation, and equivalent vacation days from common accrual methods.

How the Vacation Accrual Calculator Works

The calculator estimates earned vacation time from the accrual method you select. If your policy gives vacation days per year, it converts days to hours, divides by pay periods per year, and multiplies by completed pay periods.

If your employer grants a fixed number of vacation hours per pay period, the calculator multiplies that amount by completed pay periods. If vacation accrues per hour worked, it multiplies hours worked by the accrual rate.

Vacation Accrual Formula

Annual vacation hours = vacation days per year x hours per workday.

Vacation earned per pay period = annual vacation hours / pay periods per year.

Available vacation = accrued vacation - used vacation.

Example Vacation Accrual Calculation

If you receive 10 vacation days per year and work 8-hour days, the annual vacation amount is 10 x 8 = 80 vacation hours per year.

If you are paid biweekly, 80 / 26 = 3.08 vacation hours per pay period. After 10 pay periods, 3.08 x 10 = 30.8 vacation hours accrued before subtracting any vacation already used.

What Affects Vacation Accrual?

  • Annual vacation allowance or per-period accrual rate.
  • Pay frequency, payroll cutoff dates, and pay-period timing.
  • Hours per workday when policies are written in days.
  • Waiting periods, probationary periods, and service-year tiers.
  • Accrual caps, carryover limits, and manual payroll adjustments.

Vacation Accrual vs PTO Accrual

Vacation accrual applies when the employer tracks vacation as its own leave bank. PTO accrual applies when the employer uses a broader paid time off bank. If your policy uses one combined bank, compare this page with the PTO accrual calculator.

The math can look similar, but the legal and policy treatment may differ. Sick leave, vacation, floating holidays, and general PTO may not all accrue, roll over, or pay out the same way.

Common Mistakes

  • Using annual vacation days when the policy accrues by pay period.
  • Confusing biweekly pay with semimonthly pay.
  • Entering vacation used in days instead of hours.
  • Ignoring caps, waiting periods, or recent payroll corrections.
  • Treating the estimate as the official balance without checking a pay stub or HR system.

Documents to Check

  • Employee handbook
  • Vacation policy
  • PTO policy if vacation is part of a combined bank
  • Pay stub or HR portal balance
  • Carryover and rollover policy
  • Final paycheck or separation policy

Frequently Asked Questions

How do I calculate vacation accrual?

Start with the method in your employer policy. Vacation may accrue as days per year, hours per pay period, or hours per hour worked. Then subtract vacation already used.

Is vacation accrual the same as PTO accrual?

Sometimes, but not always. Vacation may be a separate bank, while PTO may combine vacation, personal time, and sometimes other paid leave. The written policy controls the distinction.

Can my employer cap vacation accrual?

Many employers use accrual caps or carryover limits. Whether a cap is allowed or how it applies can depend on state law and policy wording, so verify current guidance.

Does unused vacation roll over?

It depends on employer policy and state or local rules. Some policies allow carryover, some cap carryover, and some may limit unused time. Verify before assuming.

Does vacation accrue while I am on leave?

It depends on the employer policy, the type of leave, and sometimes state or local rules. Check whether the policy says accrual continues during paid leave, unpaid leave, disability leave, or protected leave.

Why does my pay stub show a different vacation balance?

Payroll records may include rounding, manual adjustments, waiting periods, carryover limits, recent usage, corrections, or a different accrual date than the calculator assumes.

Should I use the PTO accrual calculator instead?

Use the PTO accrual calculator if your employer uses a general PTO bank. Use this vacation accrual calculator if your employer tracks vacation separately.
