What it means
Under a use it or lose it rule, anything unspent or untaken at the cutoff is forfeited, meaning it is taken away without payment. The unused amount is not carried forward or paid out, unless a specific exception applies.
In employee benefits, the best-known example is the flexible spending account, a US arrangement in which an employee sets aside pre-tax pay for medical or dependent care costs. The employee chooses the amount at the start of the year, and funds left at the end may be forfeited, subject to limited carry-over or grace period options that an employer may offer.
Holiday and paid time off policies work similarly in some companies and countries. Some laws restrict forfeiture and require payout or carry-over, so the rule is a policy choice that varies by location and must be checked against local employment law.
In corporate budgeting, departments that expect their unspent budget to be taken back often spend it before the year ends. This behaviour, sometimes called the year-end spending rush, can lead to purchases of little value just to avoid losing the money.
For finance leaders, the rule creates both a control and a risk. It stops cash sitting idle and forces planning, but it can distort decisions, so some companies allow partial carry-forward or manage budgets on a rolling basis instead.
For accounting, forfeited benefits may reduce liabilities, and the treatment depends on the plan terms.
In practice
Real-world examples
Example 1
A marketing department has $120,000 of budget left in the last month of the year. The manager knows that unspent funds will be removed, so she rushes through a conference sponsorship that was not planned. The finance director later questions whether the spend was needed.
Example 2
An employee joins a company that offers 20 days of paid leave and lets staff carry over no more than 5 days. By December she has taken 12 days and holds 8 unused. She loses 3 days after the carry-over limit, so she books time off before the year ends.
Example 3
A school district gets a restricted grant that must be spent within the fiscal year. Facing the deadline, the finance team spends the remaining $60,000 on equipment that was already on its wish list. The money is used, but only after the district has weighed what it genuinely needed.
Think of it
It is like a gift voucher with an expiry date. If you do not spend the balance before the clock runs out, the store keeps the money and you lose the value completely.
Formula
Calculation
Forfeited amount = Amount set aside - Eligible amount actually used
An employee elects to put $3,000 into a flexible spending account for the year, and the plan has no carry-over or grace period. Eligible claims during the year total $2,250. Forfeited amount = 3,000 - 2,250 = $750. If the employee's marginal tax rate is 25%, the tax saved on the $3,000 contribution = 3,000 x 25% = $750. The forfeiture exactly cancels the tax saving, so the employee is no better off than if they had not joined the plan, although they did pay for the care they used with pre-tax money.Case study
Seen in the real world
Stonebridge Logistics is an illustrative, fictional freight company with twelve departments, each given an annual budget that lapsed at year end. The finance director noticed that spending in the final month was about 35% higher than the monthly average, and the extra spending was concentrated in items like furniture and training.
She calculated that roughly $210,000 of the final month spend was bought only to avoid losing budget. The leadership team agreed to a new rule that let each department carry forward up to 10% of unspent budget, and to require a short justification for any spend over $5,000 in the last month.
In the illustrative result, year-end spending dropped to near the monthly average and the company kept about $150,000 of cash that would otherwise have been spent. Departments also became more realistic when they set their budgets in the first place.
Watch out
Common mistakes
- Assuming unused benefits are always paid out, when under a use it or lose it rule they are forfeited unless the plan or the law says otherwise.
- Choosing a large flexible spending amount without a realistic estimate of costs, which risks forfeiting money that was already deducted from pay.
- Treating year-end spending as a sign of good budget use, when it can show the budget was too generous or the rule is distorting choices.
Questions
People also ask
Does use it or lose it apply to all holiday allowance?
No, the rules differ by country, state and contract, and some places require unused leave to be carried over or paid out.
Can an employer soften the rule on a flexible spending account?
Yes, within the limits of the law, an employer may offer a short grace period or a limited carry-over amount instead of full forfeiture.
How can a company avoid wasteful year-end spending?
It can allow a modest carry-forward, use rolling forecasts, or review late-year purchases more closely before approving them.
