Pricing Test Calculator
Is a higher price with fewer buyers better than a lower price with more? This calculator compares two price points on revenue and contribution, using the number of buyers you expect at each and one unit cost. It is for founders and product owners deciding what to charge before running a live test or a launch.

What this startup tool gives you
You get one sentence saying which price contributes more, then a table with price, expected buyers, revenue, and contribution for Price A and Price B. It is a quick way to frame a pricing discussion around margin instead of top-line revenue alone.
What you enter
- Currency: USD, EUR, or GBP
- Price A, per unit
- Expected buyers at Price A
- Price B, per unit
- Expected buyers at Price B
- Unit cost: the variable cost of serving one buyer
Worked example
The example uses Price A of USD 49 with 80 expected buyers and Price B of USD 79 with 40, with a unit cost of USD 9. Revenue is $3,920 at A and $3,160 at B. Contribution is (49 − 9) × 80 = $3,200 at A and (79 − 9) × 40 = $2,800 at B, so the tool reports that Price A contributes more.
How do you compare two prices by contribution?
For each price, revenue = price × expected buyers, and contribution = (price − unit cost) × expected buyers. The same unit cost is used for both prices. All five inputs are required and cannot be negative.
The lead sentence names the price with the higher contribution, or says they match. The buyer counts are your own estimates, not a demand curve; the tool does not predict how many people will buy at each price.
Tips before you use the result
- Base the buyer estimates on something observed, such as conversion at a past price or a small live test, not a guess.
- Include every per-buyer cost in unit cost: payment fees, delivery, support time. A low unit cost flatters the higher-volume price.
- Fixed costs are not in this comparison. A price that wins on contribution can still lose if serving twice the buyers needs more staff.
- Run the same test with a few different buyer counts at Price B to find the point where it overtakes Price A.
Frequently asked questions
How do I test two price points for my product?
Estimate how many buyers you expect at each price, enter one unit cost, and compare contribution, not just revenue. This calculator shows both for each price. Then check those buyer estimates with a real test, such as offering each price to a different group of new customers.
What is contribution in pricing?
Here, contribution is what is left after the unit cost is paid, multiplied by the number of buyers: (price − unit cost) × expected buyers. It is what is available to cover fixed costs and profit, which makes it a better yardstick than revenue when prices differ.
Can a lower price make more money?
Yes, if enough extra buyers come in. In the example, USD 49 with 80 buyers contributes $3,200, more than USD 79 with 40 buyers at $2,800, even though the higher price earns more per sale. Whether that happens for you depends on your real buyer counts, which only a live test can confirm.
Do I need to register to use the pricing calculator?
There is no registration step. Your prices and estimates are kept in this browser between visits and are not sent to an account or a server. That makes it safe to try confidential price points. Use Copy output to paste the comparison table into a pricing memo or a team chat.

Synergy, Decoded: What It Actually Means
Synergy is the extra value created when two businesses or teams combine, so that the whole is worth more than the parts added up. In mergers and acquisitions it usually means specific savings or extra sales the combined company expects to get, and it is often the main reason given for paying a premium for a deal.
Valuation, Decoded: What It Actually Means
Valuation is the estimated value of a company, usually expressed as a single price for the whole business. For public companies it falls out of the share price. For private companies and startups it is agreed between buyers and sellers, often during a funding round, using methods like revenue multiples, comparable deals and discounted cash flow.
