Formula

Core Formula

\text{Final} = (\text{Base} - \text{Discounts}) \times (1 + \frac{\text{Tax}}{100}) + \text{Shipping} + \text{Fees}

How it works: Apply all discounts and coupons to the base price first. Calculate tax on the discounted amount. Then add shipping and any additional fees. The result is the exact amount charged at checkout.

Review and Methodology

Updated Mar 26, 2026

This calculator runs locally in your browser. Inputs are converted into the units required by the formula, and the result is paired with supporting references so you can verify the method before using it for planning or estimates.

Worked Example

Base: $100, $10 off, 5% off, $3 coupon, 8% tax, $5 shipping, $2 fees

1Step 1: After $10 off = $90

2Step 2: After 5% off = $90 x 0.95 = $85.50

3Step 3: After $3 coupon = $82.50

4Step 4: Tax = $82.50 x 0.08 = $6.60

5Step 5: Subtotal = $82.50 + $6.60 = $89.10

6Step 6: Final = $89.10 + $5 + $2 = $96.10

Result: You pay $96.10 (saved $13.90 off pre-tax price).

What Goes Into the Final Checkout Price?

The price you see on a product listing is rarely what you pay at checkout. Discounts reduce the price, but tax, shipping, and fees add to it. This calculator accounts for every component to show you the exact amount that will be charged.

Discounts are applied in order: dollar off first, then percentage off, then coupon
Tax is calculated on the post-discount price (standard in most jurisdictions)
Shipping is added after tax (shipping is typically not taxed in most US states)
Other fees include processing fees, gift wrapping, insurance, expedited handling
The final price can be significantly different from the advertised price, especially for online purchases

Use this calculator before checkout to avoid surprise charges. Enter all known costs to see exactly what you will pay.

You can also calculate changes using our Tax and Discount Calculator, Compare Price Calculator, Coupon Savings Calculator or Sale Price Calculator.

Frequently Asked Questions

In what order are discounts applied?

This calculator applies:

(1) fixed dollar discount.

(2) percentage discount on the reduced price.

(3) coupon amount. Tax is then calculated on the final discounted price. Shipping and fees are added last.

Is tax calculated on the discounted price?

Yes. Tax is computed on the post-discount price, which is the standard method in most US states and most other countries.

Is shipping taxed?

In most US states, shipping charges are not subject to sales tax. This calculator adds shipping after tax. Check your state rules for exceptions.

What counts as other fees?

Common extra fees include payment processing fees (especially on platforms like PayPal or Venmo), gift wrapping charges, shipping insurance, assembly fees, and expedited handling surcharges.

How do I use this for budgeting?

Enter your estimated purchase details to see the true total cost. This helps you budget accurately instead of just looking at the product price. It is especially useful for large purchases where tax and shipping add significant amounts.
