Direct credit mode: 4 hours per posting. No annual earning limit is modeled.
Inspect the forecast ledger
Every scheduled posting and modeled leave event, in date order. Use it to check the forecast line by line before you trust the ending balance.
Hours display rounded to two decimals; calculations retain full precision. “Accrual blocked by cap” is future credit not added, never forfeiture of earned hours.

Every posting and leave event
Illustrative forecast from 2026-09-01 through 2026-09-04; credit before leave on a shared date.
| Date | Event | Before | Potential credit | Credited | Accrual blocked by cap | Requested leave | Leave debit | Shortfall | After |
|---|---|---|---|---|---|---|---|---|---|
| 2026-09-04 | Credit | 38 | 4 | 2 | 2 | n/a | 0 | 0 | 40 |
| 2026-09-04 | Modeled leave debit | 40 | n/a | 0 | 0 | 8 | 8 | 0 | 32 |
Why same-day order can matter
When a credit and a leave request land on the same date, the order you pick changes the balance. The example below shows both.
This illustrative example starts at 38 hours, with a 40-hour cap, a 4-hour posting and an 8-hour leave request on 2026-09-04. Credit first adds 2 hours. The cap blocks 2 hours before the leave is taken. Leave first creates room for the full credit.
After that date, the balances are 32 hours with credit first and 34 hours with leave first. Change the order above to inspect both ledgers.
Illustrative credits and leave on 2026-09-04, in hours
| Order | Event | Before | Credited | Blocked by cap | Leave debit | After |
|---|---|---|---|---|---|---|
| Credit first | Credit | 38 | 2 | 2 | 0 | 40 |
| Credit first | Leave | 40 | 0 | 0 | 8 | 32 |
| Leave first | Leave | 38 | 0 | 0 | 8 | 30 |
| Leave first | Credit | 30 | 4 | 0 | 0 | 34 |
Later credits can bring the two ending balances back together when the cap is reached.
How we calculate your forecast
The forecast walks each scheduled posting in date order and keeps a running balance under your cap.
The tool schedules each posting after your opening date through your target date. At every posting, it adds the smaller of the scheduled credit or the remaining space under the cap. Planned leave is processed in date order using your chosen same-day rule.
In annual mode, annual allowance divided by the editable policy divisor gives hours per posting.
The actual scheduled count is separate: the illustrated calendar year contains 27 biweekly postings, starting on 2026-01-01, while its policy divisor remains 26. An illustrative 104-hour allowance divided by that policy divisor produces 4 hours per posting and 108 hours across that calendar.
This tool applies all scheduled credits and does not enforce an annual earning limit; check whether your policy has one. An annual allowance is not treated as an already-earned opening balance.
Employer rules and legal context
A few federal and California rules shape how vacation accrual works. This forecast stays illustrative; your employer's policy governs.
The FLSA itself does not require vacation time off, paid or unpaid. See the U.S. Department of Labor Hours Worked Advisor.
In California, earned vacation vests as labor is performed, reasonable accrual caps may pause future earning until the balance falls below the cap, and forfeiting earned vacation because it was not used by a deadline is prohibited. See California DIR vacation guidance for all three points.
Don't use the forecast to determine whether your employer's cap is lawful.
