Convert a miles or points balance into a dollar figure, so you can see roughly what you are sitting on and whether it is enough for the trip you have in mind.
Converting miles to dollars is useful for a sense of scale and misleading if you treat it as money in an account. Points are not currency; they are a claim on a specific set of redemptions, priced by the program, that can be repriced at any time. The dollar figure this tool produces tells you roughly what your balance could do today under normal conditions, which is a genuinely useful thing to know and not the same as what it is worth.
Two people with the same balance can honestly arrive at very different totals, because one assumes the cash-out rate and the other assumes a strong partner redemption. Neither is wrong; they are answering different questions. If you want a conservative floor, use the guaranteed cash-back rate. If you want to know what the balance could achieve when used well, use a realistic transfer redemption you would genuinely book. Do not use the best redemption anyone has ever reported.
Seeing a large dollar figure is satisfying and slightly dangerous. Points depreciate quietly as programs raise award prices, and a balance you have been admiring for three years has almost certainly lost purchasing power over that time. If this tool shows you a number bigger than you expected, treat it as a prompt to plan a trip rather than a reason to keep collecting.
The number here is an average; a booking is specific. Once you have a rough figure, price the trip you actually want with the award vs cash calculator and confirm the seat exists with Award Travel Finder. A balance is only worth what you can book with it on the dates you can travel.
