How to interpret your result
A 100% discount cannot be reversed to a unique original price.
Compare quantities on a common unit basis. Apply successive discounts to the reduced price each time. A low unit cost only creates value if the quantity is useful and additional purchase costs are considered.
Frequently asked questions
Can I simply add two discount percentages?
No. A second discount applies to an already reduced price, so the remaining-price factors must be multiplied.
How do I use the reverse discount calculator?
Enter discounted price, discount (%). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Original price = discounted price ÷ (1 − discount/100).
What should I check before using the result?
A 100% discount cannot be reversed to a unique original price.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
