Points vs Cash Flight Calculator

First, it computes the award’s effective cents-per-point (CPP): CPP = (Cash fare − Award taxes/fees) / Points required × 100. It then converts the points redemption into a cash-equivalent cost: (Points required × your point valuation) + Award taxes/fees, and calculates the net savings vs paying cash. Finally, a flexibility choice can slightly tilt the result if one option is meaningfully harder to change or refund.

Your point valuation is the key driver—two people can see different recommendations from the same flight. Taxes/fees matter a lot when award fees are high, and the “flexibility” setting only nudges the decision: it won’t override a clearly negative points value proposition. The tool also assumes the award seat is available and that you’re comparing the fare itself (not baggage, seat selection, upgrades, or elite perks).

If award taxes/fees exceed the cash fare, the calculator will flag it as likely a poor redemption (unless you strongly value flexibility or are correcting for points expiration). If cash fare is very low, paying cash is often favored because preserving points tends to be better. If your CPP is close to your valuation (within about ±10%), expect “It depends,” since small differences—and real-world change/refund rules—can flip the recommendation.

This doesn’t model points you might earn by paying cash (opportunity cost), transfer bonuses, or points expiration risk—so your “true” valuation may be different from your entered value. It also simplifies cancellation/change policies into a single flexibility preference, not detailed fare rules. For the best results, use realistic taxes/fees on the specific award and a point valuation that reflects your typical best use.
