How Colorado sales tax works
Every taxable purchase in Colorado starts with the 2.9% state rate. On top of that, the city, county, and any special districts where the sale happens add their own rates. Averaged across where people actually shop, locals pay about 7.89% all-in.
To figure the tax yourself: multiply the price by 0.0789. A $250.00 purchase generates $19.72 in tax for a total of $269.72. To back the tax out of a receipt total, divide by 1.0789 instead. The calculator above does both.
