Steam sale backlog calculator

How much backlog is that Steam sale actually adding?

A 70% discount can save money and still add hundreds of hours to the pile. Estimate the cost, apparent saving and time commitment before you buy.

Discount does not equal value

This calculator does not tell you whether a game is worth buying. It makes the trade-off visible: the cash price falls during a sale, but every game you genuinely plan to finish also adds time to your backlog.

Use it before a sale checkout

If your cart contains several games, use the average normal price, average discount and a realistic average game length. The result shows how many weeks of your normal backlog time the purchase represents.
