To earn the same total contribution as before this discount, you may need roughly 33% more volume (illustrative).
What is a free discount, and what goes on one?
The discount calculator helps you model different discount scenarios (percentage off, flat amount, early payment discount) and see the impact on your revenue.
Key components
- Original price — the full price before discount.
- Discount type — percentage, flat amount, or tiered.
- Discounted price — the final price after applying the discount.
- Revenue impact — how much revenue you're giving up.
How to use this tool
- Enter your standard project fee or hourly rate.
- Input the discount percentage or fixed amount requested.
- Review the new total and the exact dollar amount you are giving up.
- Determine if the discount requires a reduction in scope.
Why this matters
Discounting without math leads to resentment. This tool helps you visualize exactly how much profit you are sacrificing, encouraging you to trade value (like reducing scope) instead of just dropping your price.

Frequently asked questions
Sequential percent discounts multiply rather than add. Ten percent then ten percent is not twenty percent off — this tool shows the combined effect.
Check whether you started from net or gross amounts and whether tax is included. Mixing bases is the most common discount mistake.
Strategic discounts can win strategic work, but habitual discounting trains clients to wait for cuts. Pair discounts with tighter scope or longer terms.
It shows the cash discount and the implied annualized cost of skipping it — helpful when clients ask for “2/10 NET 30” style terms.
The margin impact section relates your sale price drop to profit as a percent of revenue so you see whether the concession still clears your cost floor.
Up to four sequential percent-off steps, because real quotes sometimes chain “friend rate”, seasonal promo, and invoice-level adjustments.
An illustrative multiple of units you might need to sell at the discounted price to earn the same profit dollars as before — a gut check, not a demand forecast.
Yes — use the tab that solves for the implied discount from an original price to the price the client asked for.
