What this tool does
A sticker that says '30% off' is easy; a sale that stacks a further 'extra 10% at checkout' quietly is not, because the second discount applies to the reduced price, not the original. This calculator handles both plain and stacked offers, showing the true final price, the amount you save, and the combined effective percentage so you can compare a 30+10 deal honestly against a straight 40% off.
Choose the currency you actually pay in — rupees, dirhams, riyals, dollars, pounds, euro or Indian rupees — and every figure is formatted with the right symbol and decimal rules using the browser's built-in locale, so a PKR amount drops the decimals and a USD amount keeps two. There is no guesswork about whether 2,500 means two thousand five hundred or two million.
Because shoppers rarely buy just one item, the page also prints a small table applying the same discount to several higher prices, so you can see at a glance what the deal does to a bigger basket. When the maths matters, download that table as a CSV and keep it. All of it happens in your browser: no price you type is recorded anywhere.

Tips
- A 30% then 10% stack is a 37% total cut, not 40% — the table makes that visible.
- Round-check fast offers: enter the price and a 10% discount to sanity-estimate a tenth.
- For a bundle, put the total basket price in the top field rather than per-item.
- Use the CSV when comparing two retailers' stackable deals side by side.
- Tax and shipping are not included — this works on the discounted merchandise price.
Frequently asked questions
How does a stacked discount work?
The second percentage is applied to the already-reduced price: final = price × (1 − first%) × (1 − second%). Two 10% stacks give 19% off in total, not 20%, because the second 10% is smaller in rupee terms.
Which currencies are supported?
PKR, AED, SAR, USD, GBP, EUR and INR. Each is formatted through the browser's Intl.NumberFormat so symbols and decimal places match local convention.
Does it include sales tax?
No — it calculates the discounted merchandise price only. Add your local VAT or GST separately if you need the checkout total.
Is the discount calculator free to use?
Yes — Discount Calculator has no usage cap, no sign-up and no watermark, and it is not a trial: the page is a static file on https://wafasmart.tech with no billing backend behind it.
Can I compare two discounts?
Enter the first offer, read the effective percentage, then change the fields for the second — the effective % line tells you which deal cuts more.
Can I use it on my phone?
Yes. Discount Calculator is mobile-first: one column, big tap targets, and the system keyboard opens with sensible number/text input. On iPhone, Files and the share sheet feed the picker the same way Downloads does on Android.
