Sick Leave Accrual Calculator

See your current sick leave balance.

How it is calculated

The tool multiplies the hours you earn each pay period by the number of periods you have worked, then subtracts the hours already taken: accrued = hours_per_period × periods_worked and balance = accrued − hours_used. All three fields are in hours (periods are a plain count) and all three are required; a blank or negative entry returns no result. Hours used cannot be more than hours accrued either, so a request for more than you have earned shows no result rather than a negative balance; using exactly the accrued amount gives 0.00 hrs. Results are shown to two decimals. It applies one flat accrual rate only: it has no annual cap, no carry-over limit and no waiting period, so if your policy has any of these, reduce the periods or hours by hand before entering them.

Worked example

Suppose you earn 3.08 hours of sick leave per pay period, you have worked 26 periods and you have used 24 hours. Accrued hours are 3.08 × 26 = 80.08 hrs. The balance is 80.08 − 24 = 56.08 hrs. The tool prints a balance of 56.08 hrs, an accrued total of 80.08 hrs and a used figure of 24.00 hrs.

Common mistakes

  • Entering the number of days instead of hours. The three fields are hours; convert a day with your normal shift length first (for example 1 day = 8 hours).
  • Putting the total hours earned per year into the per-period field, or the number of months into the periods field. The periods count must match the pay frequency used for the accrual rate.
  • Ignoring an accrual cap. The tool keeps adding hours without limit, so a result above your employer's maximum is not what you can actually bank.
  • Entering hours used that exceed hours accrued, for example 90 against 80.08. The tool shows no result; check whether part of the leave was advanced or whether the periods worked are understated.
  • Leaving the used-hours field blank when you have taken none. Type 0, otherwise no result is shown.

About this calculator

Most employers let sick leave accrue gradually — a fixed number of hours earned per pay period, per week worked, or per month of employment, often up to an annual or lifetime cap — rather than granting the full allotment on day one. This calculator tracks the running balance: you enter the hours earned per period, the number of periods worked and the hours you've already used, and it shows the hours accrued and how many sick hours you currently have available. It does not apply any cap, so if your policy has one, compare the result with your cap yourself.

Employees rely on this to plan time off without accidentally going negative or losing accrued hours to a use-it-or-lose-it policy, while HR and payroll teams use the same accrual math to administer leave banks fairly and consistently. Because accrual rates and caps vary widely by employer, state, and country, plugging in your own policy's numbers gives a far more useful answer than any generic sick-leave rule of thumb.
