Airline Miles and Points Value Calculator

When you use points or miles, you don’t pay the cash price, but you usually still pay taxes and fees. The cash you save, split across every point you spend, is what each point was worth on that booking. Compare it with your own target, the least you’d accept for a point, to see whether to use points or pay cash.

The formula

cash you save = cash price − taxes and fees on the award − value of miles you’d earn on the cash booking
value per point = cash you save ÷ points needed
(× 100 for cents, pence, paise or fils per point; × 100 again for the value per 100 points in main units)
your points at your target = points needed × your target
extra value = cash you save − your points at your target
break-even cash price = fees + miles you’d earn + points × your target
miles earned = cash price × miles per unit, valued at your target
buy points: bought = (points needed − points you have) ÷ (1 + bonus %), rounded up to a whole block; cost = bought × price + fees
card points = miles needed ÷ (miles per card point × (1 + transfer bonus %)); value per card point = cash you save ÷ card points
cash + points value = (cash price − cash paid) ÷ points used

Worked example

With the starting inputs, a flight costs $500 in cash or 25,000 points plus $50 in taxes and fees.

• Cash you save: 500 − 50 = $450.
• Value per point: 450 ÷ 25,000 = $0.018 = 1.80¢ per point ($1.80 per 100 points, $18 per 1,000).
• The example target is 1.2¢, so the 25,000 points are worth 25,000 × $0.012 = $300 to you.
• You get 450 − 300 = $150 more than your target: 1.8 ÷ 1.2 = 150% of it. A great use of points by your own measure.
• At your target the award only pays off while the cash price is above 50 + 300 = $350, and it is worth spending up to 450 ÷ 0.012 = 37,500 points.

(The starting amounts follow your currency, for example ₹30,000 with ₹3,000 of fees and a 70 paise target, which gives 27,000 ÷ 25,000 = 108 paise a point. They are round made-up figures, not real prices or programme values.)

Miles you give up

If the $500 ticket would earn 5 miles per $1, you give up 500 × 5 = 2,500 miles. At your 1.2¢ target they are worth $30, so the award really saves 450 − 30 = $420, or 420 ÷ 25,000 = 1.68¢ per point. As a % back, 6% of $500 is the same $30.

Buying points

Points at 1.5¢ each with a 50% bonus cost 1.5 ÷ 1.5 = 1¢ each in effect. For 25,000 points you need 25,000 ÷ 1.5 = 16,667 bought, rounded up to 17,000 in blocks of 1,000, which gives 25,500 points. They cost 17,000 × $0.015 = $255, plus $50 fees = $305, which is $195 less than the $500 cash price. With 10,000 points already and no bonus you buy 15,000 for $225, and the trip costs $275.

Transfer ratios

At 2 : 1 you need 25,000 × 2 = 50,000 card points, so each card point is worth 450 ÷ 50,000 = 0.90¢. At 1 : 1 with a 30% transfer bonus, 25,000 ÷ 1.3 = 19,230.8, so you need 19,231 card points, worth 450 ÷ 19,231 = 2.34¢ each.

Cash + points

If the same flight is also offered for 12,500 points plus $300, those points save 500 − 300 = $200, or 200 ÷ 12,500 = 1.60¢ per point: less than the 1.80¢ of the full award.

Comparing options

The example options in Advanced, against the 1.2¢ target:

Business class: (3,000 − 120) ÷ 70,000 = 2,880 ÷ 70,000 = 4.11¢. Made-up figures to show the sum.

Verdict bands

• At least 125% of your target: a great use of points.
• 100–125%: good, it beats your target.
• 90–100%: about your target, a close call.
• Below 90%: paying cash and keeping the points may be better.

Tips

• Use the cash price of the same flight or room on the same dates, with the same bags and seat rules.
• Only count the cash price if you would really have paid it. If you would have flown a cheaper option, use that price.
• Fuel and carrier surcharges on some awards can be large. Always put them in the fees.
• Points can lose value when programmes change their charts, so holding a big balance has a cost too.
