The math stores hope you won’t do
Retail pricing is designed to be hard to compute in your head. “40% off, plus an extra 15% for members, tax added at the register” is a sum almost nobody can work out while standing in an aisle. That gap between the advertised discount and the real checkout total is where overspending happens.
The Discount Calculator app closes that gap. Enter the tag price, tap the discount, stack a second one if you have a coupon, add your local tax rate, and the final price, the amount you saved, and the effective discount rate are on screen before the cashier finishes scanning.
The effective rate matters more than it sounds: a “20% + 10%” stacked deal is actually 28% off, not 30%. Seeing the true number helps you compare deals honestly across stores, especially during long sale events when every shop frames its discount differently.

Frequently asked questions
How do I calculate a discounted price?
Multiply the original price by (100 − discount) ÷ 100. For example, 25% off an $80 item is 80 × 0.75 = $60. The app does this instantly and also shows how much you saved.
Do stacked discounts add up?
No. A 20% discount plus an extra 10% coupon is not 30% off. The second discount applies to the already-reduced price, so the combined discount is 28%. The app calculates stacked discounts correctly.
Can it include sales tax?
Yes. Add your local sales tax or VAT rate and the calculator shows the after-tax total, so the number matches what you actually pay at checkout.
Can I save discount rates I use often?
Yes. Mark any discount or tax combination as a favorite and reuse it with one tap the next time you shop.
Is the app free?
Yes, the app is free to download and use on iPhone and Android.
Does it work without an internet connection?
Yes. All calculations run on your device, so it works in stores with no signal.
