Formula Used

The online pay calculator uses the following formula to calculate the final amount:

Final Amount = (Base Amount × (1 + Tip Percentage)) × (1 - Discount Percentage) × (1 + Sales Tax Rate)

Where:

  • Base Amount is the original amount before any adjustments.
  • Tip Percentage is the percentage of the base amount added as a tip.
  • Discount Percentage is the percentage of the base amount subtracted as a discount.
  • Sales Tax Rate is the applicable sales tax rate in the USA.

This formula ensures that all adjustments are applied in the correct order to get an accurate final amount.

Worked Example

Let's walk through an example to see how the calculator works:

  1. Enter a base amount of $100.00.
  2. Select USD as the currency.
  3. Enter a tip percentage of 15%.
  4. Enter a discount percentage of 10%.
  5. Select a sales tax rate of 8%.
  6. Click "Calculate".

The calculator will perform the following calculations:

Step 1: Apply the tip - $100 × 1.15 = $115.00

Step 2: Apply the discount - $115 × 0.90 = $103.50

Step 3: Apply the sales tax - $103.50 × 1.08 = $111.94

The final amount to pay is $111.94.

  • The "Final Amount" is the total you need to pay after all adjustments.
  • If you entered a tip, the calculator shows how much extra you're paying.
