Sick Leave Accrual Calculator

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, up to an annual or lifetime cap — rather than granting the full allotment on day one. This calculator tracks the running balance by combining your accrual rate, the hours you've already used, and time elapsed to show exactly how many sick hours you currently have available.

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.
