WooCommerce Discount Calculator

The WooCommerce Discount Calculator converts a percentage discount into a sale price, customer savings, and post-discount profit. It helps merchants check a promotion before applying a coupon or scheduled sale to a product.

A discount that looks modest to shoppers can have a much larger effect on profit because cost does not fall with price. Showing both the sale price and remaining margin makes that tradeoff visible.

Customer Savings = Original Price × Discount Rate

Discounted Price = Original Price − Customer Savings

Profit After Discount = Discounted Price − Unit Cost

Where:

  • Original Price = regular customer price
  • Discount Rate = percentage reduction expressed as a decimal in the formula
  • Unit Cost = direct cost assigned to one sale

The calculator uses the entered values directly and rounds only for display.

What the result means

Use the result as a planning estimate and compare it with consistent historical data.

Actual WooCommerce reports may differ because of tax settings, refunds, fees, timing, and data definitions.

Given:
- Original price: $72
- Discount: 25%
- Unit cost: $30

Calculation:
$72 × 0.25 = $18 savings
$72 − $18 = $54 sale price
$54 − $30 = $24 profit

Result: The customer pays $54 and saves $18. The sale retains $24 in contribution profit.

Can I enter a 100% discount?

Yes. The sale price becomes zero, and profit equals the negative unit cost.

Does the calculation include coupon stacking?

No. Combine sequential discounts into an effective rate or calculate each discount step separately.

Why does a 20% discount reduce profit by more than 20%?

The discount reduces revenue, while unit cost remains unchanged. Profit therefore falls faster than price when margins are limited.

Should shipping be part of unit cost?

Include variable shipping or fulfillment cost when it is paid by the store and tied to the sale.

How is this different from the price estimator?

This tool evaluates a discount from an existing price. The price estimator works backward from cost and a target margin to suggest a list price.
