PTO Caps and Carryover: Why a Simple Projection Can Differ
Carryover adds an opening balance; a balance cap limits what can be held. A cap applied after every accrual can differ from one applied only at the end.

Separate the two limits
A carryover limit applies when moving a balance into a new policy year. A balance cap can apply throughout the year. A person may have a 40-hour carryover limit and a 160-hour balance cap; these are different inputs.
Timing matters
Start with 100 hours under a 100-hour cap. If ten hours accrue while capped and ten hours are then used, the actual balance may be 90. An ending-balance formula would calculate 100 + 10 − 10 = 100. The calculator explicitly uses the latter simplified method.
Reconcile with transactions
For an exact audit, list accruals and leave debits in date order and apply the cap at each posting. Ask whether accrual stops while capped or is tracked separately. Avoid projecting an exact entitlement from annual totals alone.
Try it with your numbers
Calculate PTO earned per pay period and project an available balance.
Are a carryover limit and an accrual cap interchangeable?
No. One may restrict the balance transferred into a new year; the other may restrict the balance held during the year. Applying one number to both can produce the wrong projection.
What records are needed for a cap audit?
Use the opening balance, every accrual, every leave debit, their posting dates and the policy effective on those dates. Annual totals alone omit the event order.
Can a carryover limit and an accrual cap apply to the same balance?
A policy can define both, but they act at different events. Keep the year-boundary adjustment separate from the cap applied when new hours are earned.
A balance cap of 160 hours limits the amount held at one time. An annual accrual limit of 160 hours limits the amount earned during the policy year. A carryover limit of 40 hours limits the amount moved into the next year. Entering all three as a single cap changes the meaning of the calculation.
For example, someone holding 156 hours who receives an eight-hour credit would reach 164 before limits. A strict 160-hour balance cap would allow only four more hours at that moment. If leave is deducted before the credit instead of after it, the outcome can differ. Check the sequence used by payroll rather than assuming the displayed monthly net change tells the whole story.
