Cash or points: how to decide
Work out the cents per point first — it takes seconds and rules out the obviously bad redemptions. Then ask three things the math cannot: would you genuinely have paid the cash price, what else were those points going to do, and are the two options really the same trip? If the answers are yes, nothing better, and yes, use the points. Cheap fares are usually better paid in cash, because the cents-per-point figure will be poor and you keep the flexibility.
Start with the arithmetic
Run the booking through the redemption value calculator. This is not the decision, but it filters out the redemptions that are clearly poor value, and it takes almost no time.
If the result is well below what the program typically returns, that is usually enough to stop there. You are spending a flexible asset badly, and the cash price is probably low enough that paying it is painless.
Question one: would you have paid cash?
If the honest answer is no, the redemption is not saving you the cash fare — it is buying you something you would otherwise have gone without. That can still be a fine use of points! Upgrading a trip you were taking anyway is a legitimate thing to do with them.
But be clear about which one it is, because it changes the comparison. Measuring a business-class award against a fare you would never have bought inflates the result and quietly justifies burning a lot of points.
Question two: what else were those points for?
Points spent now are not available for the trip you actually care about later. If you are saving for something specific, a mediocre redemption today has a cost beyond its cents-per-point figure.
The counterweight is that miles depreciate. Holding out indefinitely for a perfect redemption is its own way of losing value — see how airline miles work. "Spend reasonably well, reasonably soon" beats both extremes.
Question three: is it the same trip?
A calculator treats the award and the cash fare as interchangeable. Often they are not. An award routing with two connections, a long layover and a 6am departure is a worse product than the nonstop you priced it against, and the difference is worth real money to most people.
Adjust the cash side to the fare for a comparable trip, not the cheapest fare on the route. That is the comparison that reflects the choice you are actually making.
A redemption worth declining
A domestic round trip is selling for $240. The airline will also sell it for 30,000 miles plus $11.20 in fees. This is the sort of booking people make on autopilot.
($240.00 cash − $11.20 award fees) ÷ 30,000 points × 100 = 0.76 cents per point
Well under a cent per point. Paying the $240 and keeping 30,000 flexible miles is almost certainly the better decision here — those miles are worth considerably more applied to a long-haul redemption later.
The mistake: calling it a free flight
An award ticket is not free. You paid for the points somehow — through spending, through an annual fee, or through the cash you did not get back as a rebate — and you almost always pay taxes and fees on top.
The word "free" is doing damage here because it removes the comparison. Once you accept that the points had a cost, the question becomes what else that cost could have bought, which is the right question.

Questions people ask
Is there a cents-per-point figure below which I should always pay cash?
No universal one, and we would be inventing it if we claimed otherwise. A useful habit is to compare against the reference value for that specific program, which our calculator does automatically. Well below it, pay cash.
What about cashing points out for a statement credit?
That is usually a much lower rate than a good travel redemption, but it is predictable. When the alternative is a poor redemption made under time pressure, a predictable low rate can be the better outcome. Price both.
Should I use points for cheap flights to save cash?
Generally no. Cheap fares produce poor cents-per-point figures almost by definition, and you are spending a flexible asset to save a small amount of money.
