Divide the annual PTO allowance by the policy’s number of accrual periods. A 120-hour allowance across 26 periods earns about 4.6154 hours per period.
Use the policy denominator
Biweekly pay dates usually mean 26 checks, but some years contain 27. The PTO policy may still use 26 accrual periods, change the denominator, or apply a fixed rate. A paycheck count does not automatically establish the accrual rule.
Work through a balance
With 120 annual hours, 13 completed periods produce 60 earned hours. Add 8 hours of carryover and subtract 16 hours used to get 52 hours available before a cap. Keep the full accrual precision until the balance is calculated.
Rounding changes the result
Rounding 120/26 to 4.62 before each of 26 postings gives 120.12 hours. A payroll system may carry extra precision or make a final adjustment. Compare the stated method, not only a single rounded paycheck line.
Try it with your numbers
Calculate PTO earned per pay period and project an available balance.
With 26 accrual periods, 80 ÷ 26 is approximately 3.076923 hours per period. Thirteen complete periods earn 40 hours before used leave, carryover or caps.
Does a partial pay period earn a full accrual?
That depends on the policy. The calculator uses the period quantity entered and does not determine eligibility or waiting periods.
What happens if I round 120 ÷ 26 to 4.62 each period?
Crediting 4.62 for 26 periods gives 120.12 hours. A policy may carry more precision or use an adjustment, so reconcile using its actual posting rule.
For a policy that posts a fixed amount every two weeks, use annual PTO hours ÷ policy accrual periods. The denominator is normally 26, but the written policy or payroll configuration controls. Do not silently change it just because a calendar happens to contain a 27th biweekly payday.

Keep more precision than the pay stub displays when checking a year-to-date balance. Rounding 4.615385 to 4.62 before every posting produces 120.12 hours after 26 periods.
Fixed accrual versus accrual by hours worked
A fixed biweekly policy credits the same amount after each eligible period. An hours-worked policy multiplies eligible hours by a rate, so a 72-hour pay period can earn less than an 80-hour period. At an annual rate of 80 PTO hours per 2,080 eligible hours, the hourly factor is 80 ÷ 2,080 = 0.0384615.
Use the calculator mode that matches the policy. Do not count paid leave, overtime or unpaid time as eligible hours unless the policy says they are included.
Questions people ask about PTO accrual
How much PTO do you accrue per week?
Divide the annual allowance by the number of weekly accrual periods in the policy. Eighty hours across 52 weeks earns about 1.5385 hours per week.
How do I calculate my PTO?
Start with the opening balance, add earned PTO, and subtract used PTO. Apply carryover limits, caps, waiting periods and transaction order according to the actual policy.
How many 8-hour days is 80 hours of PTO?
Ten days. If a full absence day is charged at another shift length, divide 80 by that number instead.
Does a 27-paycheck year create extra PTO?
Not automatically. Some policies still divide and post the annual allowance across 26 accrual periods; others post on every eligible paycheck. Verify the policy denominator before projecting the balance.
Calculate PTO Accrual from Hours Worked — For an hourly accrual policy, multiply eligible hours by the PTO earned per eligible hour. Use the eligible-hour definition and rate from your employer's policy.
PTO for a Partial Pay Period: Two Calculation Methods — Partial-period PTO depends on the accrual method. An hourly policy uses eligible hours; a fixed-period policy may use a specified proration rule or no proration at all.
