              How to add sales tax

              Multiply the price by (1 + tax rate ÷ 100). $120 with 8.25% tax is 120 × 1.0825 = $129.9.

              The tax itself is the price times the rate: 7% of $49.99 = $3.5.

              Finding the price before tax

              To remove tax from a total, divide by (1 + rate ÷ 100): $129.90 ÷ 1.0825 = $120. Smart mode does not understand this one yet; use the division above.

              Frequently asked questions

              Is taking 8% off the same as removing 8% tax?

              No. Removing tax means dividing by 1.08; subtracting 8% from the total gives a slightly lower, wrong price.

              Which rate should I use?

              Your combined state and local rate. It varies by state, county and city, from 0% in a few states to above 9% in some cities.

              How much is 6% tax on $250?

              250 × 6 ÷ 100 = $15, for a total of $265.
