When a client asks for a discount, how far can you safely go?
Price negotiation is unavoidable in B2B sales. When a client asks for a discount in exchange for a bulk order or a long-term contract, it's tempting to set the discount rate on the spot to preserve the relationship. But negotiating without a clear margin floor risks closing a deal that looks like a win on paper but actually loses money. Calculating your limit — "I can discount up to this point" — before the negotiation starts is the foundation of a safe pricing strategy.
This calculator takes your cost and minimum margin to keep, calculates the lowest price that still protects that margin, and derives the maximum discount rate from the gap to list price. For example, on a product with a $70 cost and $100 list price, setting a 20% minimum margin gives a lowest sellable price of $87.50 and a maximum discount rate of 12.5%. Knowing this limit in advance lets you respond to a client's discount request with a number backed by logic, instead of improvising on the spot.
That said, it's usually smarter in practice to open the negotiation with a bit of room above your true maximum rather than offering exactly the maximum upfront. Also, for bulk orders where logistics cost per unit drops, you can apply a lower margin floor — but always separately verify that the total profit dollars still meet your target even at that lower rate.
Frequently Asked Questions
Divide cost by (1 - minimum margin rate) to get the lowest price that still protects your margin. Divide the gap between that price and list price by list price to get the maximum discount rate.
It varies by industry and deal size, but businesses commonly set a floor of at least 10-15% margin to cover fixed costs and leave room for reinvestment.
Bulk orders spread out logistics and inventory costs, so a lower margin rate can be acceptable compared to small orders — but you should still separately confirm that total profit dollars meet your target.
