Is 30% off then an extra 20% the same as half price? It is not, and the gap is bigger than most people guess. The Discount Calculator settles that in a second, along with the sale price, the amount saved and what a stacked voucher really takes off.
Short answer: The Discount Calculator is a free tool on EizTools that works out sale prices and savings. Enter the original price and the discount, including stacked offers, and it returns the final price with the working.
What is Discount Calculator?
It handles the arithmetic behind any price reduction. Type the question in plain words and the Discount Calculator gives you the sale price, the money saved and the effective percentage when more than one offer applies.
Sale Price, Savings And Stacked Offers
Single discounts are easy. It is the layered ones that catch people out. Thirty percent off, then twenty percent off the reduced price, comes to 44% off in total, not 50%. Shops know this. Working it out at the shelf, on your phone, takes about ten seconds here.
Stacked offers
Ask for two or three discounts in sequence and the answer shows the effective total, not the sum of the labels.
Savings in money
Percentages are abstract. The output gives the amount saved in currency, which is what actually decides a purchase.
Rounding control
Round Result cleans up the awkward figures that come out of double discounts.
Getting The Format You Want
| Setting | What it does | Best for a discount |
|---|---|---|
| Format | Plain, Table, Step-by-Step or Formula + Result | Plain for a quick answer, Table when comparing offers |
| Precision | Auto, 2 Decimals, 4 Decimals, Whole Number, Exact | 2 Decimals, since prices carry pence or cents |
| Round Result | Toggle that tidies the final figure | On, unless you need the exact number |
Output Style is worth changing when the question involves more than one offer. Answer Only gives the price. Steps + Answer shows how the second discount applied to the reduced price, which is the part people want to see proved.
How Does Discount Calculator Work?
A shopper is looking at a coat with a sale sign and a code from an email.
- Type the question: "coat is 180, marked 30% off, plus a code for an extra 15% at checkout, what do I pay?"
- Select an AI model above the prompt box.
- Choose Percentage, set the Format to Step-by-Step, and keep precision at 2 Decimals.
- Turn on Show Steps and Round Result.
- Generate and read both figures: the price and the total saved.
- Ask a follow up in a new run to compare against a rival shop's flat 40% off.
Quick test Ask for the effective single discount when two offers stack. That one number tells you whether "30 plus 15" beats a straight 40% somewhere else, without doing the sum twice.
Who Uses It
- Shoppers checking whether a sale is as good as the sign claims
- Sellers setting a discount that still leaves a margin
- Anyone pricing a bundle, where each item carries a different reduction
- Market stalls and small shops working out end of day prices
EizTools gives each job a free tool of its own, with no registration, no limit on the page and a model selector sitting above your result. Once the discount is decided, the wording around it matters just as much, and the Landing Page Copy Generator handles the sale page that has to explain the offer clearly. Everything else sits in the tool library.
Frequently Asked Questions
Can the Discount Calculator handle two discounts at once?
Yes. Describe both in the prompt and say which applies first. The answer shows the price after each stage and the effective total, which is always less than adding the two percentages.
Does it work out the original price from a sale price?
Yes. Ask it in reverse, such as "45 after 25% off, what was the original", and it works backwards. Set Output Style to Steps + Answer to see the method.
Can it include tax in the calculation?
Mention the tax rate in your prompt and say whether it applies before or after the discount. That order changes the final figure, so being specific matters.
Is it accurate for pricing decisions?
The arithmetic is simple and the tool shows its steps, so check the result before you use it on a shop wide sale. For a single purchase, the answer is easy to verify at a glance.
Discount maths is easy to do wrong quickly, which is exactly why sale signs are written the way they are. Ask for the effective percentage, look at the money saved rather than the label, and the decision gets a lot simpler.
