Sale Price Calculator

Sale price formula

The calculator takes a percentage off a price, then adds tax and shipping to get a total. Sellers use it to set a markdown or clearance price; buyers use it to check what "25% off" comes to at the till.

sale price = original price × (1 − discount ÷ 100)

The saving is the original price times the discount. Tax is added to the sale price, not to the original price, and shipping comes last.

How to use the sale price calculator

1. Enter the original (pre-discount) price.
2. Enter the discount percentage.
3. Enter your local sales tax rate. It is charged on the discounted subtotal, not on the original price.
4. Set the quantity if you are pricing several units.
5. Add the shipping cost if it is charged separately from the item price.
6. Click Calculate Total. Clear resets every field.

How to calculate a sale price with tax and shipping

An item normally priced at $100, marked down 25%, sold as two units with 8% sales tax and $10 flat shipping:

1. Discount: $100 × 25% = $25 off each unit.
2. Sale price per unit: $100 − $25 = $75.
3. Subtotal for 2 units: $150.
4. Tax: 8% of $150 = $12.
5. Final total: $150 + $12 + $10 shipping = $172.
6. Total saving from the discount: $25 × 2 = $50.

Is sales tax charged before or after a discount?

The calculator charges tax on the discounted subtotal. That is how a store's own discount works in California, for example: under CDTFA Regulation 1671.1 a retailer coupon reduces the amount the tax is charged on.

A manufacturer's coupon can be different. When the maker reimburses the store, California counts that reimbursement as part of the sale, so the tax is charged as if on the full price. Other states set their own rules.

What a markdown leaves you after eBay fees

A discount cuts the price, and marketplace fees then come out of what is left. On eBay a $60.00 listing pays out $51.44 at full price and $38.48 at 25% off.

The buyer saves $15.00, but your payout drops by $12.96, because the fees shrink with the price.

Run your own discounted price through the matching fee calculator: the eBay fee calculator, the Etsy fee calculator or the Depop fee calculator. The profit margin calculator then shows how much of the new price is profit.

What the sale price calculator leaves out

Tax is one flat percentage on the discounted subtotal. The calculator does not model places that tax shipping, charge tax before a discount, or split tax across state and local rates.

Shipping is added once per order after tax, whatever the quantity.
