Vacation Balance Calculator
Formula Used
Base Annual Accrual = selected annual rule × FTE ratio.
Daily Accrual = Base Annual Accrual ÷ 365.
Accrued To Date = Daily Accrual × eligible days worked during the selected window.
Available Before Usage = Starting Balance + allowed Carryover + Accrued To Date + Bonus Adjustment + Manual Adjustment.
Current Balance = Available Before Usage − Used To Date.
Projected End Balance = Current Position + future accrual − Planned Future Use, limited by the allowed negative balance.
Liability Value = Positive Balance × Payout Rate.

Frequently Asked Questions
1. What does this calculator measure?
It estimates current vacation balance, projected balance, remaining accrual, carryover impact, and payout liability using your chosen accrual policy and date range.
2. Can I show results in days instead of hours?
Yes. Choose days as the display unit. The tool converts hours into days using the entered weekly hours divided across a five day workweek.
3. How is carryover handled?
The calculator applies the smaller value between carryover entered and carryover cap. This prevents overstating available leave beyond policy limits.
4. Does it support part time employees?
Yes. Use the FTE ratio field. For example, a half time employee can use 0.50 so accrual is reduced proportionally.
5. What happens if an employee can go negative?
Enter the permitted negative balance. The calculator will not project balances below that policy threshold.
6. Why include payout rate?
Payout rate converts positive vacation balances into an estimated cash liability. This helps finance or HR teams understand balance sheet exposure.
7. Can I use this for planning future leave?
Yes. Add planned future use and a projection end date. The schedule and chart will estimate how balances move through the remaining months.
8. Is this suitable for every leave policy?
It covers many common policies, but unique union rules, anniversary accruals, or jurisdiction specific laws may require custom adjustments before production use.
