About Discount Calculator
Retailer pricing is deliberately confusing — buy-two-get-one offers, percentage-off versus cash-off vouchers, unit-price comparisons across different pack sizes. Discount Calculator cuts through the marketing to give you the actual best deal in a few seconds. It runs in your browser so you can use it standing in a shop aisle without an app.
How to use Discount Calculator
- Enter the original price and any discount type (percentage, fixed amount, or multi-buy).
- Add competing prices or pack sizes if you want a side-by-side comparison.
- Press Compare or Calculate to see the final price per unit and total saving.
- Use the copy button to keep a record for a purchase decision or price-match request.
Frequently asked questions
- Does the tool pull live prices from any retailer?
- No. Discount Calculator works with the prices you enter. It performs the maths; you supply the numbers from the shelf, website, or flyer.
- How does it handle stacked discounts (e.g., 20% off, then an extra 10% off)?
- Stacked discounts are not the same as 30% off. The tool applies each discount sequentially — 20% off a £100 item gives £80, then 10% off £80 gives £72, not £70.
- Can I compare prices in different currencies?
- The tool is currency-agnostic. As long as you enter all prices in the same currency, the comparison is valid. It does not perform live foreign-exchange conversion.
- Does the tool calculate cashback or loyalty point value?
- Some tools in this category include a cashback or points-to-cash converter. If yours does, enter the programme's points-to-value rate; otherwise calculate that separately.
- Is the tool useful for bulk or wholesale buying decisions?
- Yes. Unit-price comparison is the core function — it is equally useful for consumer retail, catering supplies, or office procurement.
