About the Tiered & Volume Pricing Calculator
This tiered pricing calculator prices an order against a quantity price-break schedule in the two ways suppliers and SaaS companies actually use. Under graduated (tiered) pricing, each unit is charged at the rate of the band it falls in — the first 100 at one price, the next 400 at another, and so on. Under all-units volume pricing, the whole order is charged at the rate of the band the total quantity reaches.
Enter your break points and unit prices one per line, type the order quantity and pick the model you sell or buy under. You get the order total, the average price per unit, the total under the other model for comparison, and a chart of how the average unit price falls as quantity grows. The table shows exactly how many units land in each band.
It is useful for building a quantity-discount price list, checking a supplier quote, setting API or seat-based SaaS pricing, or spotting the "volume cliff" where buying a few more units costs less in total under all-units pricing. Quantities above your last break point are charged at the last listed price.
With the default inputs, the order total (selected model) is $5,825.00. Change any value above to recalculate instantly.
How to use the tiered & volume pricing calculator
- 1Type each price break on its own line as "up-to quantity: unit price".
- 2Finish with an open-ended top tier such as "1000+: 5".
- 3Enter the order quantity and any flat setup fee.
- 4Choose graduated or all-units volume pricing to set the headline total.
- 5Compare both totals and check the chart for volume cliffs before quoting.
Formula and method
With graduated (tiered) pricing, the order quantity Q is split across the bands: units 1 to B₁ are charged P₁, units B₁+1 to B₂ are charged P₂, and so on, and the subtotals are added. The price of the next unit is simply the price of the band the next unit falls into.
With all-units volume pricing, the calculator finds the band whose upper limit is at or above Q and charges every unit at that band’s price. Because the whole order reprices when you cross a break point, volume pricing can make a slightly larger order cheaper in total — the so-called volume cliff. Any fixed fee F is added under both models, and quantities above the last break are charged at the last listed price.

Worked examples
750 units on a four-tier schedule
Graduated pricing charges 100 units × $10 = $1,000, 400 × $8 = $3,200 and 250 × $6.50 = $1,625, a total of $5,825 or about $7.77 per unit. Under all-units pricing the whole order lands in the 501–1,000 band, so 750 × $6.50 = $4,875 — $950 cheaper.
All-units pricing just below a break point
At 500 units every unit is priced at $8, so the order costs $4,000. Graduated pricing would be $1,000 + 400 × $8 = $4,200. Buying 501 units would drop the whole order to $6.50 per unit ($3,256.50), a classic volume cliff.
SaaS seats with a setup fee
Graduated: 10 seats × $30 = $300, 40 × $25 = $1,000 and 10 × $20 = $200, plus the $500 setup fee = $2,000, or $33.33 per seat including the fee. All-units pricing would bill all 60 seats at $20 ($1,200) plus $500 = $1,700.
Frequently asked questions
What is the difference between tiered and volume pricing?+
Tiered (graduated) pricing charges each band of units at its own price, so only units above a break point get the lower rate. Volume (all-units) pricing charges every unit at the rate of the highest band the order reaches, so crossing a break point reprices the entire order.
Which pricing model is better for the seller?+
Graduated pricing protects revenue because early units always pay the higher rate and totals never fall as quantity rises. All-units volume pricing is simpler to communicate and gives buyers a stronger incentive to order more, but it creates cliffs where a bigger order costs less.
What is a volume pricing cliff?+
Under all-units pricing, an order just below a break point can cost more than one just above it, because crossing the break lowers the price on every unit. Sellers often fix this with a minimum charge per band or by switching to graduated pricing.
How do I write the tier list?+
Put one tier per line as the upper quantity of the band followed by the unit price, for example "100: 10" then "500: 8". Use a plus sign, such as "1000+: 5", for the open-ended top band. Ranges like "101-500: 8" also work; the upper number is used.
How is the average unit price calculated?+
It is the order total, including any fixed setup fee, divided by the number of units. It is the fairest single number for comparing quotes from suppliers that use different tier structures.
