Open PTO CalculatorReal workplace situation
The visible balance is not always the balance on the vacation date. If another pay period accrues before the request, the projected balance may be enough; if not, the request may create a negative balance.
Current PTO: 18 hours. Accrual before trip: 6 hours. Requested PTO: 32 hours. Projected balance after request: -8 hours.
Working rule
Projected PTO balance = current balance + confirmed future accrual - requested PTO hours.

Checklist before you rely on the number
Key checks
- Start with the current approved PTO balance.
- Add only accrual that happens before the requested time off.
- Convert requested days into hours.
- Subtract the requested hours.
- Check whether negative balances are allowed.
Notes from real use
Some systems show projected accrual automatically; others show only current earned time.
A holiday inside the request can reduce PTO needed if it is paid separately.
If the balance goes negative, final-paycheck rules may matter if you leave before rebuilding it.
Mistakes that change the result
Do not add accrual that happens after the vacation.
Do not assume negative PTO is allowed.
Do not count a holiday as PTO if the policy pays it separately.
