## Overview

30% off $150 leaves a sale price of $105.00, a saving of $45.00. Find 30% by taking 10% ($15.00) and tripling it, or multiply the price by 0.70 for what you pay. Stack a second coupon below to see how an extra markdown compounds.

## Method

The sale price is the original price multiplied by each discount factor in turn: sale price = original × (1 − d1 ÷ 100) × (1 − d2 ÷ 100). The amount saved equals original minus sale price. The effective discount percentage is (1 − combined multiplier) × 100, which is always less than d1 + d2 when both are positive. Sales tax is then added to the discounted price: final = sale price × (1 + tax ÷ 100). If only one discount is entered the second factor is 1 and drops out of the calculation.
