It is very hard to assign a monetary value to points and miles. Specifically, points issued by banks (Ultimate Rewards, Membership Rewards, Thank You points, Arrival “miles”) and airline mileage programs (AAdvantage, MileagePlus, SkyMiles, Easy Returns, Avios, etc., etc. etc.)
Valuations vary wildly depending on who you ask. But if you ask me, it’s simple. You want to get at LEAST two cents of value out of each point or mile.
And that’s the smoking gun right there. Don’t waste time trying to assign some sort of arbitrary value out of your points and miles. You want to shoot for a minimum value of $.02 each.
