Discount Calculator

Price and percent off in — sale price and savings out, live as you type.

sale price
you save
Saving = price × %% ÷ 100. Runs on your device — nothing is sent.

How to use it

  1. Enter the original price.
  2. Enter the discount percentage.
  3. Read the sale price and the amount saved — updated live.

What you pay vs what you save

A discount question is really two numbers: the saving (price × percent ÷ 100) and the final price (what’s left). Shops advertise the percent because it sounds bigger than the saving usually is — the calculator shows both so you can judge the deal on the actual money. Mental-math shortcuts and the stacked-discount trap are covered in the discount guide.

Questions people ask

Is my file uploaded to a server?

No. Every other online converter uploads your file to a server. Lokafile never uploads anything — the work happens in your browser, so your file physically never leaves your device.

Do I need to sign up or pay?

No account, no payment, no watermark, no CAPTCHA before download. Free.

Does it work offline?

Yes — once loaded, you can disconnect and it still works. You can even install Lokafile as an app.

Is there a file size limit?

No artificial cap. The only limit is your device’s memory.

How do I calculate a discount?

Multiply the price by the percentage and divide by 100 — that’s the saving. Subtract it from the price for what you pay. 30% off £60: save £18, pay £42.

How do stacked discounts work?

They multiply, not add: 20% off then 10% off is 28% off total, not 30%, because the second discount applies to the already-reduced price.
