Calculating Steam Account Value without Bundle games

Use of the calculators then manually remove all bundle games?

The problem is that some people actually purchased the game which later became part of a bundle. There's no way for those calculators to tell which was purchased outside of a bundle especially if you buy from sites such as GamersGate, GMG, Amazon, Gamefly, Impulse and so on which also gives you steam keys.

Went through my Steam games not long ago and manually added every actual price I paid into a site called [edit][strike]SteamGauge[/strike] (GaugePowered, same as kanga linked -- was away from the comp and didn't remember it right)[/edit]. Took me about a week or two. If I can do it, I'm sure you can, with a comparatively smaller library. You'll actually have an easier time of it if you want to exclude bundle games, since you can just set those all to 0.00 or hide them. I set each new game's price to a portion of the whole bundle's price for my calculations -- if there were 8 games in a bundle, but only five were new to me, and the bundle cost $5, I'd set each of their values at $1.00.

You still have to manually adjust the price, but try this one
