TSA PreCheck Break-Even: Two Departures a Year Is Usually Enough
2026-09-18
Short answer: A $78 five-year enrolment costs $15.60 a year. At 25 minutes saved per departure and personal travel time valued at about half the wage rate — $17.50 an hour on a $35 wage, following US DOT guidance — the fee is recovered after about 54 minutes of queueing saved, which is roughly 2.1 departures a year. Below that, it is bought for predictability rather than value.
The arithmetic
annual cost = enrolment fee ÷ years of validity
break-even departures = annual cost ÷ (minutes saved ÷ 60 × hourly value of time)Worked example — a 78 enrolment valid for five years, 25 minutes saved per departure, and time valued at 17.50 an hour (half of a $35 wage, following US DOT’s approach to valuing personal travel time):
| Input | Value |
|---|---|
| Annual cost | $15.60 |
| Value of 25 minutes | $7.29 |
| Break-even departures per year | 2.1 |
Above roughly two departures a year, the enrolment returns more than it costs. Below that, it does not — on time value alone.
| Departures per year | Annual time value | Annual cost | Net |
|---|---|---|---|
| 1 | $7.29 | $15.60 | −$8.31 |
| 2 | $14.58 | $15.60 | −$1.02 |
| 4 | $29.16 | $15.60 | +$13.56 |
| 12 | $87.50 | $15.60 | +$71.90 |
Where the inputs actually move
The break-even is so low that the interesting question is not whether the fee is worth it but whether the 25 minutes is real for you.
- Airport and time. A regional airport at 06:00 on a Tuesday may have no queue at all, in which case the saving is zero however many times you fly. A large hub on a holiday weekend can exceed 25 minutes several times over.
- What you carry. Part of the saving is procedural rather than queueing — not removing shoes, belt, laptop or liquids. That part applies even when the standard queue is short, and it is the part frequent flyers value most.
- Whether you check bags. If you are at the airport early because of a bag drop, minutes saved at screening convert into waiting at the gate rather than into time at home.
The part the arithmetic misses
At two departures a year the expected saving and the cost are within a dollar of each other, which means the decision is not really about the average. It is about the worst case: the day the standard queue is 50 minutes and the flight is the one you cannot miss.
Expedited screening reduces the variance of the airport experience more than it reduces the mean. Someone who flies rarely but cannot afford to miss the flight they do take is buying something real — it is just insurance rather than a saving, and it is worth naming that way.
What would reverse the conclusion
- A card that reimburses the fee. If you already hold it, the cost is zero and the arithmetic no longer needs to be run. If you would take the card for the reimbursement, price the whole card.
- An airport where the lanes are frequently closed. Expedited screening that is not staffed at the hour you fly saves nothing.
- A higher value of time. Business travellers whose time is genuinely billable should use the full rate rather than half, which drops the break-even to about one departure a year.
- Family travel. Each traveller needs their own enrolment, so a family of four multiplies the cost while the queue time saved per trip stays roughly the same for the group.
