Average Selling Price Calculator
Average selling price (ASP) is the total revenue a product earned divided by the number of units sold. It is a backward-looking figure: it tells you what customers actually paid on average across every batch, discount and channel. It is not the same as working out what price to charge, which starts from your cost and the margin you want. This page covers both, because the two get confused constantly.
The calculator above handles the first one. Enter the units and price for each batch and it returns the weighted average. The weighting matters: the ASP is almost never the simple average of your prices, and the worked example below shows how far apart the two answers land.

Formula Used for the Calculator
Average Selling Price = Total Revenue Earned by a Product ÷ Number of Units Sold
Written out for several batches, that is (units1 × price1 + units2 × price2 + …) ÷ (units1 + units2 + …). Each price is weighted by how many units sold at it, which is what makes this a weighted average rather than a plain one.
What is the Average Selling Price?
The Average Selling Price is the total revenue earned from selling products divided by the total number of units sold. It helps determine the typical price at which products are being sold.
Average selling price, selling price per unit, and cost of sales are three different things
These three get searched for interchangeably and they answer different questions. Check which one you actually need before you use any calculator.
| What you want | The calculation | What you need to know first | Direction |
|---|---|---|---|
| Average selling price | Total revenue ÷ units sold | What you already sold, and at what prices | Backward looking, measures what happened |
| Selling price per unit | Cost × (1 + markup), or cost ÷ (1 − margin) | Your unit cost, and the markup or margin you want | Forward looking, sets a price |
| Cost of sales (COGS) | Beginning inventory + purchases + labour + materials + other costs − ending inventory | Your inventory and production costs for the period | Backward looking, measures cost not price |
The third one is worth naming precisely because it is often assumed to be a simple purchases figure. The IRS sets out its components on Schedule C of Form 1040, lines 35 to 42, in Publication 334, Tax Guide for Small Business: beginning inventory, plus purchases, cost of labour, materials and supplies and other costs, minus ending inventory.
Worked example 1: why the average selling price is not the average of your prices
Say a product sold in three batches: 100 units at $80, 50 units at $120, and 25 units at $60.
- Total revenue = (100 × $80) + (50 × $120) + (25 × $60) = $8,000 + $6,000 + $1,500 = $15,500
- Total units = 100 + 50 + 25 = 175
- Average selling price = $15,500 ÷ 175 = $88.57
- The plain average of the three prices ($80 + $120 + $60) ÷ 3 = $86.67
The two answers differ by $1.90 a unit, or $333 across 175 units, because the largest batch sold at the lowest of the three prices. Averaging the price tags instead of weighting by volume is the single most common error in this calculation, and it gets worse the more uneven your batch sizes are.
Worked example 2: a 40% markup and a 40% margin are not the same price
This is the trap in the forward calculation. Take a unit that costs $60.
| You said | Formula | Price | What you actually get |
|---|---|---|---|
| 40% markup | $60 × 1.40 | $84.00 | A margin of ($84 − $60) ÷ $84 = 28.6% |
| 40% margin | $60 ÷ 0.60 | $100.00 | A markup of ($100 − $60) ÷ $60 = 66.7% |
Same cost, same number, $16 a unit apart. Markup is measured against your cost, margin against your selling price, so a margin percentage is always the larger price of the two. If a supplier, a spreadsheet or a colleague quotes you a percentage, establish which of the two they mean before you price anything.

FAQs
How is the average selling price calculated?
Divide the total revenue a product earned by the number of units sold. Across several batches, multiply each batch’s units by its price, add those together, then divide by the total units. Weighting by volume is what makes it an average selling price rather than an average of the price tags.
Can this calculator be used for service-based businesses?
Yes, provided you can express what you sell as a countable unit and a price. Billable hours, seats, subscriptions, licences and support contracts all work. Software companies track average selling price per contract or per seat routinely. It only breaks down where there is no repeatable unit, such as a one-off fixed-fee project.
What is the difference between average selling price and selling price per unit?
Average selling price looks backward and measures what customers actually paid across everything you sold. Selling price per unit looks forward and sets what you will charge, starting from your unit cost plus a markup or a target margin. One reports a result, the other makes a decision.
How do I calculate a selling price from cost and margin?
For a target margin, divide the cost by (1 minus the margin as a decimal): a $60 cost at a 40% margin gives $60 divided by 0.60, which is $100. For a markup, multiply instead: $60 times 1.40 is $84. Margin is measured against the selling price and markup against the cost, so the same percentage produces two different prices.
Is average selling price the same as cost of sales?
No. Average selling price is what customers paid you per unit. Cost of sales, or cost of goods sold, is what the goods cost you over a period, calculated as beginning inventory plus purchases, labour, materials and other costs, minus ending inventory. One is a price, the other is a cost.
Why is my average selling price lower than my list price?
Because the average includes everything that reduced the realised price: volume discounts, promotions, channel and reseller margins, currency effects and returns. A gap between list price and average selling price is normal, and tracking that gap over time is usually more informative than the average on its own.
