How to use it

A quick estimate, without the spreadsheet.

Inputs and units

Enter original price and one discount percentage between 0 and 100.

Formula

Savings = price × discount / 100; sale price = price − savings.

Worked example

$120 with 25% off costs $90 and saves $30.

Assumptions and limitations

Taxes, shipping and stacked discounts are excluded. Successive discounts multiply rather than add.

Understanding your result

Savings is the amount removed from the original price. Sale price is what remains before any tax, delivery charge or additional promotion. Use the final checkout total to compare offers from different sellers.

A practical comparison

A $120 item discounted by 25% saves $30 and costs $90. If an additional 10% discount then applies, calculate 10% off $90 to get $81. The combined saving is $39, or 32.5% of the original price; adding the two discount percentages would overstate it.

Common mistakes

Enter the original price before this discount.
Calculate sequential discounts one after another rather than adding their percentages.
Check promotion exclusions and any minimum spend before using the estimate as a budget.

Frequently asked questions

Does the sale price include tax?

No. Tax and shipping are excluded. Their treatment depends on the seller and jurisdiction.

How do I compare two offers?

Calculate each offer using the same original price and add any delivery or other unavoidable charges. Compare the amount you would actually pay.
