Discount Calculator
Calculate discount amount and final price so you can understand the real impact of promotions on revenue and margin.
These tools are provided for educational and operational guidance only. Results are estimates and may not reflect all factors in your business. Always review calculations and use your own professional judgement before making decisions.
What is this tool?
This calculator shows you how a percentage discount changes the selling price and how much revenue you give up per unit. It helps both commercial and finance teams check promotions and negotiated discounts quickly.
Formula
Given original price and discount%, the tool uses:
Discount amount = price × discount%
Final price = price − discount amount
You can compare the final price to your target minimum price or margin to decide whether the discount is acceptable.
Example
If the original price is 100 and the discount is 15%:
Discount amount = 100 × 15% = 15
Final price = 100 − 15 = 85.
You can then compare 85 to your cost and target margin to see if this promotion still makes sense.
When should you use this tool?
- When planning promotional campaigns or clearance sales.
- When sales reps negotiate additional discounts with customers.
- When comparing alternative discount levels (e.g., 10% vs. 15% vs. 20%).
- When checking whether bundle or volume deals still protect profitability.

Frequently Asked Questions
Is a 10% discount the same as 10% margin loss?
No. A 10% price discount usually reduces your margin by more than 10%. Combine this tool with the Margin & Markup Calculator to see the true effect on profitability.
Can I chain multiple discounts?
For multiple discounts (for example, 10% then 5%), apply them sequentially using the final price from each step as the new starting price.
How do I calculate the discount percentage from two prices?
Subtract the discounted price from the original price, divide by the original price, and multiply by 100. You can do that manually and then plug the percentage into this tool.
Should I use net or gross prices?
Be consistent with how your business measures margins. If you manage profit on net-of-tax prices, use net prices here as well.
