What is the Colorado Sales Tax Rate? 

Colorado has a statewide base sales tax rate of 2.90%, one of the lowest in the country. However, local governments can impose additional taxes, resulting in a wide range of total tax rates across the state. Because Colorado is a “home rule” state, many cities administer their own sales taxes independently. As a result, the maximum combined rate ranges from 7% to 9% but can exceed 11% in some areas.

FAQs

What is profit margin?

Profit margin is the percentage of revenue that remains as profit after subtracting costs. It helps you assess the profitability of a product or your overall business.

How do you calculate gross profit margin?

To calculate the gross profit margin, subtract the cost from the revenue, divide that number by the revenue, and multiply by 100. The formula looks like this: [(Revenue − Cost) ÷ Revenue] × 100

How do you calculate a 20% profit margin?

To achieve a 20% margin, divide your cost by (1 - 0.20). This ensures that your set price will leave you with a 20% profit after covering your costs.

For example, if your cost is $80:
$80 ÷ (1 - 0.20) = $100
