About this tool
This page opens the discount calculator with 30% prefilled — enter the original price to get the sale price immediately. 30% off means paying 70% of the price: multiply by 0.7, so 150 becomes 105 and 89.99 becomes 62.99.
Thirty percent is the classic "sale season has really started" depth — common on Black Friday for clothing, home goods and accessories. The quick mental check: take three times 10% (move the decimal point, then triple it) and subtract.
Stores love pairing 30% with an "extra 20% at checkout": stack them in the calculator's two fields and you will see the real total is 44% off, not 50%. The tool shows the intermediate price, the money saved and the effective combined percent, with every value recalculated live in your browser.
Example. A price of 80 with a 25 percent discount and no second discount returns a sale price of 60 and a saving of 20.
Limit. Only two successive percentages can be applied; a third discount has no field.
