Cash vs Points Calculator (Flights)

Compare paying cash to redeeming miles on a specific flight. We calculate the real cents-per-point you'd get after taxes and tell you whether it beats baseline for that program.

BA Avios redemptions out of London regularly include $400–700 in fuel surcharges. Always include them for honest math.

How this calculator works

The math is simple: (cash price – taxes on the award) ÷ miles required × 100 = cents per point delivered. If the result beats the cpp baseline for that program, redeem the miles. If not, pay cash and save the miles for a better redemption.

The "Cash flight price" is what the same seat would cost if you paid cash. "Miles required" is what the airline wants for the award. "Taxes & fees" is what you'd still owe in cash on top of the miles — this is critical because some programs (BA, Virgin Atlantic, Lufthansa) tack hundreds of dollars of fuel surcharges onto premium-cabin awards.

When to use cash vs points (8-point decision guide)

  • Use miles when cpp delivered is above baseline. If you're getting 2.5¢ per Avios on a 50,000-Avios Club World seat that would cost $2,000 cash, redeem — you're 67% above baseline.
  • Pay cash when cpp delivered is below baseline. A 30,000-mile domestic economy seat that costs $180 cash gives you 0.6¢ per mile. Pay cash and save the miles.
  • Pay cash if you need elite status credit. Most award tickets don't earn miles or qualify for status. If you're chasing status, the cash earn might be worth more than the redemption value.
  • Use miles if you have an oversupply. Miles devalue over time. If your balance is large and you have no near-term plans, redeem strategically rather than hoarding.
  • Use miles when the cash fare is irrationally high. Last-minute fares and peak holiday pricing are where miles shine — the cash fare denominator inflates faster than the miles required.
  • Pay cash on a non-refundable booking if dates might change. Awards are usually cheaper to change/cancel ($0–125) than cash fares, but evaluate the specific program's policy first.
  • Use miles for premium cabins. Economy redemptions almost always underperform; business and first class consistently outperform baseline by 50–100%.
  • Pay cash for promotional fares. When the airline runs a 50%-off cash sale, the cpp math always favors paying cash. Save miles for everyday pricing or last-minute needs.

Worked examples

Example 1: BA Club World LHR–JFK off-peak (round-trip). Cash fare $4,200. Miles required 100,000 Avios round-trip. Taxes & fees on award $1,300. Net cash savings $2,900. cpp = (2,900 / 100,000) × 100 = 2.9¢ per Avios. That's roughly 1.9× the baseline of 1.5¢. Redeem.

Example 2: AAdvantage domestic JFK–LAX in economy. Cash fare $230. Miles required 30,000. Taxes & fees $5.60. Net cash savings $224.40. cpp = (224.40 / 30,000) × 100 = 0.75¢ per mile. Baseline for AAdvantage is 1.7¢. Pay cash.

Example 3: Virgin Atlantic Upper Class LHR–ORD. Cash fare $3,200. Miles required 57,500 Virgin Points. Taxes & fees $850. Net cash savings $2,350. cpp = (2,350 / 57,500) × 100 = 4.1¢ per Virgin Point. Baseline is 1.5¢. Strong redeem — but note the $850 in taxes is the largest item; the case for redeeming weakens if your alternative use of those Virgin Points is a partner-airline business class booking with much lower surcharges.

Why the taxes line matters more than people think

A lot of cash-vs-points calculators online ignore the taxes line entirely — and almost every BA or Virgin Atlantic transatlantic premium-cabin award has $400–700 of fuel surcharges. If you don't subtract those from the cash savings, the calculator overstates cpp by 20–30%. The math here is correct because we explicitly net out award taxes against the cash fare before dividing.

Frequently asked questions

What's a good cents-per-point for a flight redemption?

For most airline currencies, 1.5–2.0¢ per mile is a baseline "fair" redemption. Anything above 2¢ is good; anything above 3¢ is exceptional. Avios and Virgin Points have lower baselines (~1.5¢) because of higher surcharges, while Alaska and American sit around 1.7–1.8¢ baseline.

Why does my calculator give a different answer than another site's?

Most online cash-vs-points calculators don't subtract taxes and fees from the cash savings — they just divide cash price by miles. Our calculator subtracts the award booking's taxes from the cash savings first, which is the only honest way to compute the real cpp.

Should I always redeem when cpp delivered beats baseline?

Mostly yes — but consider opportunity cost. If you have a better redemption coming up (a partner-airline business class at 4¢+ per mile), holding the miles for that is worth more than 2¢ on a domestic flight, even though both beat baseline.

Does this work for hotel points?

Use our Cash vs Points (Hotels) calculator for hotel bookings — it factors in fifth-night-free and elite-night earnings, which don't apply to flights.

How do I find the cash fare to enter?

Pull it from Google Flights, Kayak or the airline's own site for the exact same flight, route and date. Match the cabin to the award — comparing economy cash to business class miles will skew the math.

What about credit card transferable points?

If you're considering transferring Chase UR, Amex MR, Capital One miles, Bilt or Citi ThankYou into an airline program for the redemption, use the destination airline's baseline cpp in this calculator. See the Points to Dollars Calculator for transferable-points value separately.
