How much are Delta Air Lines miles worth?
A mile is worth what its redemption saves you: divide the cash fare by the miles the award needs. Above ~1.95¢ per mile — what SkyMiles cost to buy here — the miles beat the fare. Price your amount live, and the verdict on your real fare lives on the SkyMiles page.

Delta Air Lines miles calculator
Type any amount in the tool above, or read the common order sizes here — both run the same arithmetic, at the same ~1.95¢ rate.
The tilde matters: this program's rate is indicative until your quote confirms it. The quote is always the binding number, never this page.
How many SkyMiles do you actually need?
Put in what the award costs and what your account already holds. This prices the difference, whether that's a small top-up or the whole award from an empty balance, and it says so when the amount lands under SkyMiles's smallest order.
How the math works
Cost = miles × rate
SkyMiles at ~1.95¢ per mile means every 1,000 miles costs ~$19.50. A 70,000-mile award is 70 × ~$19.50 = ~$1,365. No fees are added on top of the quoted rate.
When buying makes sense
Divide the cash fare by the miles the award needs: that's what the seat values a mile at. If it's comfortably above ~1.95¢, buying wins; if it's below, pay cash. The SkyMiles page's comparison tool runs that verdict on your real numbers.
Why the quote is the real number
Rates move with sourcing. The figure here prices your estimate; the quote confirms your exact rate and delivery window before anything is paid, and that confirmed number is the one that binds.
Where the break-even sits
Every award has one deciding number: what its miles cost to buy. Fare above it, buying wins. Fare below it, pay cash.
| The award | Miles it needs | Break-even fare |
|---|---|---|
| Short-haul economy, round trip (illustrative) | ≈30,000 | ~$585 |
| Long-haul economy, one-way (illustrative) | ≈45,000 | ~$877.50 |
| Long-haul business, one-way (illustrative) | ≈85,000 | ~$1,657.50 |
| Long-haul business, round trip (illustrative) | ≈160,000 | ~$3,120 |
Generic award sizes are illustrative; Delta Air Lines prices its own chart, and your route sets the real number. Taxes and carrier surcharges are billed by the airline at booking and sit outside this math. The tilde means your quote confirms the exact rate.
When SkyMiles are worth buying
Premium cabin, long-haul?
Business and first class fares clear the break-even by the widest margins. This is where buying miles most often wins.
Fare above the break-even?
Divide the fare by the miles the award needs. Above ~1.95¢ per mile, buying wins, and the further above, the bigger the saving.
Short hop in economy?
Cheap cash fares rarely clear the break-even. Pay cash, and save the miles math for the long-haul trips.
