Volume Discount Pricing Calculator

Enter the base unit price, quantity, and volume discount to find the discounted unit price and order total.

How it is calculated

You enter the base unit price, the quantity and the discount percent that applies to this order. The tool computes discounted unit price = unit price × (1 − discount ÷ 100), order total = discounted unit price × quantity and savings = (unit price − discounted unit price) × quantity. Quantity must be at least 1 and the discount must be between 0 and 100. One flat percentage is applied to every unit. The tool does not choose a tier for you: if the seller's price list has quantity breaks, look up which percent your quantity earns and enter it. It adds no tax, shipping or currency conversion, and results are rounded to cents.

Worked example

A buyer orders 400 units listed at 25 each. The seller's price list gives 10% off at this quantity. Discounted unit price: 25 × (1 − 0.10) = $22.50. Order total: 22.50 × 400 = $9,000.00. Without the discount the order would cost 25 × 400 = 10,000, so the savings are $1,000.00. If ordering 500 units moved the buyer into a 12% tier, the new total could be compared the same way.

Common mistakes

  • Applying the discount percent of a higher tier than the order actually reaches. Check the exact quantity threshold in the price list.
  • Entering the discount as a decimal (0.10) instead of a percent (10); the discount would be 0.1% and the savings almost nothing.
  • Assuming the discount applies only to units above the threshold. This tool applies it to every unit; some sellers discount only the extra units, which gives a different total.
  • Comparing totals without adding shipping, tax or setup fees. A larger order can change the freight cost and wipe out part of the saving.
  • Entering the already discounted price as the base unit price. The discount would then be taken off twice.

About this calculator

Volume discount pricing rewards larger orders with a lower per-unit price, calculated as Discounted price = Base unit price × (1 − discount%), with the order total simply that discounted price times quantity. Discounts are usually tiered — for example, 5% off at 100+ units, 10% off at 500+ — so the rate that applies depends on which bracket the order quantity falls into. This calculator applies a single flat discount percentage that you enter, so look up your tier's rate first, or run it once per tier to compare.

B2B sales teams, wholesalers, and procurement departments use this pricing structure constantly: sellers use it to incentivize bulk purchases and reduce per-order handling costs, while buyers use the same math to figure out exactly how much they save by consolidating an order or crossing into the next discount tier.

    The savings figure assumes you need every unit. A bigger order for a bigger discount only pays if the extra units will be used or resold: at 8.50 the default 500 units cost 4,250, while 400 units at the full 10.00 cost 4,000, so the discount is worth little if you only need 400. Which quantity breaks does your supplier offer?
