What is the Frequent Flyer Miles Value Calculator?
This tool tells you the real-world value of your airline miles or points for a specific award flight, expressed in cents per mile (cpm). Because miles have no fixed cash value, the only way to know if a redemption is "good" is to compare what you would otherwise have paid in cash against how many miles the airline charges — after subtracting the taxes and fees you still pay on the award.
How to use it
Enter the cash price you would pay for the exact same flight, the taxes and fees the airline charges on the award ticket, and the number of miles or points required. The calculator subtracts the fees from the cash price and divides by the miles to give you a cents-per-mile figure. A higher number means a better redemption.
The formula explained
The math is simple: $$\text{Value per mile} = \frac{\text{Ticket cash price} - \text{Taxes \& fees}}{\text{Miles required}} \times 100$$ We multiply by 100 to convert dollars per mile into cents per mile, the industry-standard way to express redemption value. As a rough guide, most major programs are worth 1–2 cents per mile; anything above 2 cpm is generally an excellent deal.
Worked example
Suppose a flight costs $450 in cash, the award ticket charges $50 in taxes and fees, and requires 25,000 miles. Net value is \($450 - $50 = $400\). Divide by 25,000 miles $$\frac{\$400}{25{,}000} = \$0.016 \text{ per mile}, \quad \$0.016 \times 100 = 1.6 \text{ cents per mile}.$$ That is a solid, roughly average redemption.
FAQ
What is a good value per mile? Most travelers aim for at least 1.0–1.5 cpm on economy and 1.5–2.5+ cpm on premium cabins. Compare your result to your program's typical valuation.
Why subtract taxes and fees? You pay those fees in cash on top of the miles, so the miles only "buy" the remaining value. Ignoring fees overstates how much your miles are worth.
Should I redeem or pay cash? If your cents-per-mile is above what you value the miles at, redeeming is worthwhile. If it is low, save the miles for a more valuable redemption and pay cash instead.
