Calculates the tax-exclusive amount and consumption tax amount from the tax-included amount.

Calculates the tax-excluded amount and consumption tax from the entered tax-included amount and tax rate. You can enter the tax rate as any percentage.

When calculating Amount excluding tax, you can select Round down or Round off to process Fraction.

To calculate the amount excluding tax, consumption tax is calculated from the amount including tax, and if Fraction is present, the selected rounding process is applied. The consumption tax is subtracted from the tax-inclusive amount to calculate the tax-exclusive amount.

When calculating consumption tax, multiply the tax-excluded amount by the tax rate percentage.

If the consumption tax is 8%, it can be calculated by multiplying the amount excluding tax by 0.08.

At this time, the respective ratios are: if the amount excluding tax is 1, the amount excluding tax is 0.08, and the amount including tax is 1.08.

Therefore, if you want to calculate consumption tax from the tax-inclusive amount, you can find it by multiplying the tax-inclusive amount by (0.08/1.08).

If there is a product that includes tax $324, and the consumption tax is 8%, it will be 324 × (0.08/1.08) = $24.

To calculate the tax-exclusive amount, divide the tax-inclusive amount by the original amount plus the tax rate.

If the consumption tax is 8%, it can be calculated by dividing the tax-included amount by 1.08.

If there is a product $324, and the consumption tax is 8%, it will be 324 ÷ 1.08 = $300.

You can calculate the tax-inclusive amount by multiplying the tax-exclusive amount by the consumption tax percentage divided by 100 and the original amount by 1, so you can calculate the tax-inclusive amount by dividing the tax-inclusive amount by that number. can be calculated.
