Reverse Award Planner
The reverse award planner answers “how many points do I need for a flight?” by working backwards from the cash fare: divide the fare by the cents-per-point value you realistically redeem at, and you get the points the flight should cost. Subtract your current balance for the gap, divide the gap by your monthly earning for the months until the award is funded — and if the wait is long, compare earning against buying miles before you commit to either.
The formula
points needed = cash fare ÷ (expected ¢/pt ÷ 100) gap = points needed − current balance (0 if covered) months to award = gap ÷ points earned per month (rounded up)
The expected cents-per-point value is your assumption, not a program fact — programs price awards dynamically, so the same fare can cost more or fewer points than this estimate. Use a value you have actually achieved, and treat the result as a planning number, never a bookable price.

| Example redemption | ¢/pt | Points needed | Gap | Months |
|---|---|---|---|---|
| Cautious floor | 1.00 | 40,000 | 30,000 | 15 |
| Fixed-value portal | 1.25 | 32,000 | 22,000 | 11 |
| Solid economy award | 1.50 | 26,667 | 16,667 | 9 |
| Strong partner award | 2.00 | 20,000 | 10,000 | 5 |
Buy vs earn: if the wait is long, a buy-miles sale can close the gap — but only when its effective cost per mile is clearly below the value you redeem at. Price the shortcut with the mile-sale break-even calculator before paying cash for points. Every pre-filled number here is a hypothetical example; award prices, taxes, and availability live in the program’s own booking flow.
Worked example (hypothetical numbers)
A route costs $400 cash and you typically redeem at 1.25¢ per point (hypothetical numbers, not a quote). Points needed = 400 ÷ 0.0125 = 32,000 points. With a 10,000-point balance the gap is 22,000 points; earning 2,000 points a month, the award is funded in 11 months. At a stronger 2.00¢ redemption the same fare needs only 20,000 points — a 10,000-point gap, or 5 months.
