Frequently asked questions
Does this calculator know my employer policy?
No. Enter the rates, caps and balances from your handbook, agreement or payroll record.
Is this legal or payroll advice?
No. Verify eligibility, carryover, payout and protected-leave rules with the appropriate employer records or professional guidance.
When should I recalculate with the Sick Leave Accrual Calculator?
Recalculate whenever the hours, rates, schedule, pay period, policy assumptions, or planned usage changes. Saving the exact inputs makes comparisons more reliable.
How accurate is the Sick Leave Accrual Calculator?
The arithmetic follows the formula shown on the page. Real payroll or policy outcomes can still differ because of contracts, jurisdictional rules, employer systems, taxes, deductions, caps, and rounding practices.
