How it is calculated
The tool takes your pre-tax amount. It multiplies it by the tax rate. That gives the tax in your currency. It then adds the tax to the price. The result is your total with tax. The calculator works it out for you.

The pre-tax amount
The pre-tax amount is the price before tax. It is the sticker or list price. Tax is added on top of it. So a bigger amount means more tax. Use the price shown before tax. So enter the figure on the label. Enter your pre-tax price.
The sales tax rate
The sales tax rate is the percent charged. It starts at the 4.225 percent state rate. Your local rate is often higher. So change it to match your area. The right rate depends on the city and county. So check your local combined rate. Enter the rate that applies.
State rate versus local rate
Missouri has a state rate and local add-ons. The state rate is 4.225 percent everywhere. Counties and cities add more on top. So the rate in your town can be higher. Some areas pass several percent more. So always use your local combined rate. Look it up for an exact total.

Common mistakes to avoid
A common mistake is using only the state rate. Your local rate is usually higher. Another is taxing an exempt item. Not everything carries sales tax. Some forget the city add-on. Others use an old rate. A clear rate avoids these traps.
