What is cents per mile (CPM)?

CPM measures how much value you extract from each mile or point. A CPM of 1.5 cents means each mile is worth 1.5 cents in flight value, so 50,000 miles equal $750 worth of flights. Most airline programs average between 1.0 and 1.5 cents per mile for economy redemptions, though premium cabin international bookings can exceed 3-5 cpp.

Why do I subtract taxes from the cash price?

Because those taxes come out of your pocket whether you pay cash or use miles. If you pay $55 in taxes on an award ticket, the net value your miles are providing is the cash price minus $55. Including taxes in the cash price would make your redemption appear more valuable than it really is.

What are the benchmark CPM values for major programs?

Benchmarks vary by source and change as programs adjust award charts. As of 2026, rough published averages are: United MileagePlus approximately 1.2 cpp, American AAdvantage approximately 1.4 cpp, Delta SkyMiles approximately 1.1 cpp, and Southwest Rapid Rewards approximately 1.5 cpp. These are averages across redemption types. Your specific redemption will vary significantly.

Do award charts change frequently?

Yes. Airlines have been moving to dynamic pricing for awards, meaning miles required for a specific flight change based on demand, season, and fare class. Delta and United have largely switched to dynamic pricing. Always check current award pricing in the airline app before planning around a specific CPM expectation.

Does this work for hotel points too?

The formula is the same: subtract any out-of-pocket resort fees or taxes, divide the net cash value by the points required, multiply by 100. The benchmark values differ by hotel program. Enter your figures using the Other program option and compare manually against your program's published benchmark.

Should I always try to maximize CPM?

Not necessarily. A 0.8 cpp redemption on miles that would otherwise expire is better than losing them entirely. If paying cash would strain your budget but you have miles to spare, below-average CPM may still be the right practical choice. CPM is a decision input, not an absolute rule.

Airline Mile Value Calculator

This calculator finds the cents-per-mile (CPM) value of any airline award redemption by comparing what you pay in miles against the equivalent cash ticket price. Enter the miles required, the cash price of the same flight, and the out-of-pocket taxes on the award ticket. The tool returns your CPM, rates it against the benchmark for your loyalty program, and tells you whether redeeming makes sense or whether paying cash is the better choice.

Cash fare: $500 minus award taxes $50 = net $450
At 1.20¢ (United MileagePlus benchmark), 50,000 miles are worth about $600 in cash.
To cover $450 net value at the benchmark, you would need about 37,500 miles.

How this tool works

The core calculation is cents per mile (CPM): CPM = (Cash Price − Taxes and Fees) ÷ Miles Required × 100. Subtracting taxes isolates the value that miles are actually delivering, since taxes must be paid on award tickets regardless of whether you pay cash or miles. The tool then compares your CPM against a per-program benchmark derived from published valuations (e.g. approximately 1.2 cpp for United MileagePlus, 1.5 cpp for Chase Ultimate Rewards). The verdict is Good (above benchmark), Fair (within 20% below), or Poor (more than 20% below benchmark). Break-even cash price is the minimum flight price at which using miles beats paying cash: Break-even = (Miles × Benchmark CPM ÷ 100) + Taxes. Key assumption: CPM benchmarks reflect average domestic coach redemptions; premium cabin and partner redemptions can produce CPM two to four times higher. Edge case: transfer partner redemptions — where flexible points transfer to an airline partner — often yield significantly better CPM than the airline's own booking portal, and comparing portal CPM alone will understate the true value of your points balance.

Worked example

You want to redeem United MileagePlus miles for a flight that costs $480 in cash. The award requires 45,000 miles and $55 in taxes. Net cash value: $480 minus $55 = $425. CPM: ($425 / 45,000) x 100 = 0.944 cents per mile. United MileagePlus benchmark: approximately 1.2 cpp. CPM of 0.944 falls below the benchmark, rating 'Fair.' If the cash price were $600, net value = $545, CPM = 1.211, which beats the benchmark and rates 'Good.'
