Formula and method
Formula
revenue = price × units sold
IEEE-754 double precision; shown to the decimals indicated.
Gross revenue before costs, returns and discounts.
Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Price per unit = 19.99; Units sold = 250.
| Result | Value |
|---|---|
| Revenue | $4,997.50 |
| Per unit | $19.99 |
Example 2
Inputs: Price per unit = 5; Units sold = 1200.
| Result | Value |
|---|---|
| Revenue | $6,000.00 |
| Per unit | $5.00 |
The first line is the headline result (revenue). Below it the revenue Calculator lists per unit, which describe the same case from other angles. IEEE-754 double precision; shown to the decimals indicated.
Gross versus net
This is gross revenue before returns, discounts and refunds. Net revenue subtracts them. If 5% of sales are refunded, $4,997.50 becomes about $4,747.63.
Revenue is not profit
Revenue is the top line; profit is what remains after costs. Pair it with the break-even and margin calculators to see how much of revenue you keep.
Revenue is not profit in practice
19.99 × 250 units = $4,997.50 of revenue. Profit subtracts the costs of producing and selling, which this page does not include.
Use the net price when discounts apply: a 10% discount makes the unit price 17.991, so 250 units bring in about $4,497.75.
How the result changes with price per unit
Holding every other input at the first worked example, this table changes only price per unit. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Price per unit | Revenue | Per unit |
|---|---|---|
| 9.995 | $2,498.75 | $10.00 |
| 19.99 | $4,997.50 | $19.99 |
| 39.98 | $9,995.00 | $39.98 |
| 79.96 | $19,990.00 | $79.96 |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Price per unit: entering "-1" shows "Price per unit must be at least 0." beside that field and no result.
- Units sold: left empty shows "Enter units sold." beside that field and no result.
Choosing between the Revenue Calculator and similar calculators
Each row shows what a related calculator on this site asks for and what it returns, so you can pick the one that matches your question.
| Calculator | You enter | It returns |
|---|---|---|
| [Marginal Revenue Calculator](/business/marginal-revenue/) | total revenue before, total revenue after and quantity before | Marginal revenue |
| [Net Profit Margin Calculator](/business/net-profit-margin-calculator/) | revenue and net profit | Net Profit Margin |
| [Contribution Margin Calculator](/business/contribution-margin-calculator/) | selling price per unit and variable cost per unit | Contribution per unit |
| [EBITDA Margin Calculator](/business/ebitda-margin-calculator/) | revenue and eBITDA | EBITDA Margin |
| [Operating Margin Calculator](/business/operating-margin-calculator/) | revenue and operating income | Operating Margin |
Background: business metrics
Business ratios depend on exactly which costs and revenues you include, so read each page's definition. Two common checks: break-even units = fixed costs ÷ (price − variable cost per unit), so $50,000 of fixed costs with a $10 price and $5 variable cost breaks even at 10,000 units; and net profit margin = net profit ÷ revenue, so $20,000 profit on $100,000 revenue is 20%.
Return on investment ignores time: 20% over five years is far less impressive than 20% in one, so compare returns over the same period.
Assumptions and limitations
- Net revenue subtracts returns and discounts
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for price per unit and units sold to confirm this.
Frequently asked questions
How do I handle several products?
Calculate each separately and add them.
Does it include tax?
Use prices excluding sales tax.
What is recurring revenue?
Revenue expected to repeat, such as subscriptions.
Is revenue the same as profit?
No. Revenue is the money from sales; profit is what remains after costs.
How do I calculate revenue with a discount?
Apply the discount to the price first, then multiply by units. At 10% off $19.99 for 250 units the result is about $4,497.75.
What does the Revenue Calculator calculate?
Revenue from price and units sold. It returns Revenue and Per unit.
What formula does the Revenue Calculator use?
revenue = price × units sold. Gross revenue before costs, returns and discounts.
What do I need to enter in the revenue Calculator?
You enter Price per unit ($) and Units sold.
How is the result rounded or limited?
IEEE-754 double precision; shown to the decimals indicated. Net revenue subtracts returns and discounts.
What is an example of a revenue result?
With price per unit 19.99 and units sold 250, the revenue is $4,997.50.
Where does the method come from?
The method follows: OpenStax, Principles of Accounting, Volume 2: Managerial Accounting (Rice University): revenue, price × quantity.
