So basically the formula for running count is : New Count = Previous Count + Purchases - Return

Edit: If you want to calculate this from scratch and have access to all your statements, then simply add every value under Purchases without regard to any other value in your statement. Then filter by Return, subtract all those values and you should have your current running count. Use the formula above to continue calculating it or simply keep a column for returns. Previously I mentioned Fee as a filter, but because they never fall under purchases they are already excluded from the running count. Subtracting them again would be an error.

I track my spend via an excel sheet and I can predict my next $5k threshold to within a few dollars.
