How this is calculated

  • Accrual per period = annual allowance ÷ number of periods per year.
  • Period length = 365 ÷ periods per year. Only complete periods count as accrued.
  • Blank start date means the person was already employed at the start of the year, so the full annual allowance applies.
  • Prorated entitlement — if the start date falls during the current year, the annual allowance is prorated by the fraction of the year remaining from that date.
  • Accrued to date never exceeds the prorated entitlement for the year.
  • Remaining = accrued to date − days already taken (never shown below zero).

This tool uses a simplified 365-day model and does not account for carry-over from previous years, probation periods, or accrual caps. Treat the result as an estimate, not payroll advice.

What is PTO accrual?

PTO accrual is the pace at which paid time off builds up over the year. Salaried employees usually accrue a set amount each pay period — 15 days a year is 1.25 days per month, or the same amount added after each completed month. Because people accrue on different schedules and start on different dates, two colleagues on the identical annual allowance can have very different balances today.

Proration is the surprise most people hit: if you started partway through the year, your allowance for the current year is only the portion of the year you have worked, so your balance grows more slowly than a full-year colleague's. To avoid that, this calculator applies both accrual frequency and proration, so you see a realistic number instead of the headline allowance.

PTO accrual FAQ

How is PTO accrued? Most companies accrue PTO per pay period: the annual allowance divided by the number of pay periods gives the amount added each period.

Is PTO prorated in the first year? Often yes. If you start mid-year, many policies prorate the first year's allowance to the portion of the year you work.

Does accrued PTO include days already taken? Accrued is the total built up so far; remaining is accrued minus days taken. This calculator shows both.

Is this a payroll-grade tool? No. It uses a simplified 365-day model and ignores carry-over, probation periods, and accrual caps — treat the result as an estimate, not payroll advice.
