An accrual cap applies when hours are earned. Leave taken before that event creates room; leave taken afterward does not restore accrual already blocked.
Distinguish three different limits
A maximum balance limits how many hours can be held when new accrual posts. An annual earning limit restricts earnings over a year. A carryover limit controls a balance transferred across a policy boundary. They are not interchangeable. The ledger models only the maximum balance during earning events; using it for an annual limit without additional records can give a misleading result.
Compare two sequences with the same totals
Start at 38 hours with a cap of 40. If five hours are earned first, only two are credited and three are blocked. Taking eight hours afterward leaves 32. If the same eight hours are taken first, the balance drops to 30 and all five earned hours fit, leaving 35. The starting balance and requested totals are identical, but the posting order creates a three-hour difference.
Use the actual posting order
Do not assume the calendar date alone resolves sequencing. A payroll system may deduct leave and post accrual on the same date in a defined order. Intious sorts dates and preserves the typed order for ties. Enter the order documented by your employer or system. If that order is unknown, calculate both scenarios and label the difference as an unresolved assumption instead of choosing the higher balance.
Reconcile blocked hours separately
The ledger’s blocked column explains why the credited accrual is lower than the requested accrual. It is not automatically an amount owed. Some policies stop earning at a cap; other arrangements may use different rules. If an authorized adjustment later restores hours, enter it as a separate earning event with the correct date and check whether the cap should apply. Keep the policy interpretation separate from the arithmetic.
Try it with your numbers
Apply dated earning and leave transactions in order to see balances and accrual blocked by a cap.
