Is buying 50 units cheaper than buying 48? With tiered pricing, sometimes it is. The Bulk Discount Calculator shows what a quantity order costs after the right tier discount applies to the whole order.
Enter a base price, an order quantity, and four tier discounts. The tool picks the tier and shows your total and savings. It also tells you how close you are to the next tier. It suits buyers, shop owners, and anyone comparing supplier quotes.

What the Calculator Does
The tool updates as you type. Six inputs feed four result cards and a tier tip.
- Final Total Order Price: your quantity times the discounted unit price.
- Discounted Unit Price: the base price after the tier discount.
- Total Dollar Savings: the original total minus the final total.
- Applied Discount %: the tier percent that your quantity earned, or "No discount" at 0%.
- Original Undiscounted Total: base price times quantity.
- Tier Tip: how many units to add to reach the next tier with a bigger discount, plus its price.
- Copy Summary and Reset buttons.
How to Use It, Step by Step
- Enter the list price in Base Price Per Unit.
- Enter how many units you plan to buy in Order Quantity, as a whole number of 1 or more.
- Type the supplier discounts into the four tier boxes, using 0 for none. Tier 1 covers 10 to 24 units and Tier 2 covers 25 to 49. Tier 3 covers 50 to 99, and Tier 4 covers 100 or more.
- Read the final total, then the four cards below it.
- Check the tier tip. Press Copy Summary to copy the results with quantity and base price. Press Reset to restore the sample figures.
The tier ranges are fixed in the tool. Only the discount percents can be changed.
The Bulk Discount Formulas
The tool finds the tier for your quantity. That one percent then applies to every unit in the order, not just the units above the cutoff.
Base Price×1 - Tier Discount %×Quantity=Final Total
- Discounted unit price = base price × (1 - tier discount ÷ 100).
- Original total = base price × quantity.
- Final total = discounted unit price × quantity.
- Total savings = original total - final total.
- Quantities under 10 get 0% off, and the card then reads "No discount".
Worked Examples
Jamal buys 45 desk lamps at a $25.00 base price. He uses the sample tiers of 5%, 10%, 15%, and 25%. At 45 units he lands in Tier 2.
| Result | Calculation | Output |
|---|
| Discounted Unit Price | $25.00 × (1 - 0.10) | $22.50 |
| Final Total | $22.50 × 45 | $1,012.50 |
| Original Total | $25.00 × 45 | $1,125.00 |
| Total Savings | $1,125.00 - $1,012.50 | $112.50 |
The tip says to add 5 units to reach 50 and unlock 15% off. That is $21.25 each, or $1,062.50 total. Jamal would get 5 extra lamps for only $50.00 more.
A second case shows the odd effect of whole-order tiers. A buyer pays $18.40 per unit. At 48 units the discount is 10%, so the total is $794.88. At 50 units the discount is 15%, so the total is $782.00. The larger order costs $12.88 less.
How to Read the Results
Final Total Order Price is what you would pay before tax and shipping. The tool does not add either one.
Discounted Unit Price helps you compare suppliers. Divide any quote by its quantity and set it beside this number.
Applied Discount % displays as, for example, "10% Off". It shows "No discount" when the tier percent is 0 or the quantity is under 10.
Getting the Most From Tiers
Look at the cost of the gap to the next tier. If extra units cost less than you would save, the jump can pay off. That holds only if you can sell or use them. Extra stock also carries storage cost, which the inventory carrying cost calculator estimates.
Compare the discounted price to your own costs too. The cost per unit calculator shows your full cost per item. The profit margin calculator shows what you keep after selling. To check a single percent-off deal, use the discount calculator.
Ordering in bulk also changes how often you reorder. The economic order quantity calculator finds a balanced order size. Browse more tools in the finance and business calculator hub.
Limitations and Assumptions
- The whole order gets one tier percent. Tiers are not marginal, so there is no stepped pricing.
- Tier cutoffs at 10, 25, 50, and 100 units are fixed and cannot be edited.
- Tax, shipping, and handling are not included.
- Quantity must be a whole number of 1 or more. A blank, 0, negative, or decimal quantity shows a message and the results show "--".
- Each tier discount must be filled in and between 0 and 100. A blank or out-of-range entry shows a message.
- Tier percents may fall as quantity rises. The tool then shows an amber warning, and the results stay visible.
- The tip names the first higher tier with a larger discount. It does not compare total costs across tiers.
FAQs About the Bulk Discount Calculator
What is a bulk discount?
A bulk discount is a lower unit price for buying more units at once. Suppliers offer it to move larger volumes and cut their handling costs.
How do tiered discounts work here?
Your quantity falls into one tier. That tier percent then comes off the price of every unit in the order, not only the extra units.
Why can a bigger order cost less than a smaller one?
A higher tier lowers the price of all units. Near a cutoff, the savings can outweigh the cost of the added units, as the 48 versus 50 example shows.
Does the calculator include tax or shipping?
No. The total covers only price times quantity. Add sales tax and delivery charges yourself before comparing quotes.
Can I change the tier quantity cutoffs?
No. The cutoffs of 10, 25, 50, and 100 units are built in. You can change only the four discount percents.
Is the biggest discount always the best buy?
Not always. Buying more than you can sell or use ties up cash and storage space. Weigh the savings against those holding costs.
