Everyday money
This section handles everyday money questions: discounts, final prices and whether an offer is as good as it looks.
The calculations are for reference and stay away from banking products — no loans, rates or investment projections here.
What these calculators cover
- Sale price and the amount saved.
- Percentage off from the original and final price.
- Stacked discounts, which never simply add up.
Reading an offer
Shops often list discounts one after another: “20% off plus another 10%”. The second cut applies to the reduced price, so the total is smaller than the sum — quicker to verify with a calculator than in your head at the shelf.
Frequently asked questions
Is sales tax included?
No, the calculation works from the item price.
Can I find the price before a discount?
Yes, the reverse mode derives the original price from the final price and the percentage.
Do two discounts add up?
No: 20% and 10% come to 28%, not 30%.
