The revenue calculator multiplies your selling price by the number of units sold to calculate total sales revenue. Use it to check actual sales or compare price-and-volume scenarios. The result is revenue before costs—not profit.
How to use the revenue calculator
- Enter Price: Use the selling price of one unit in dollars. If you offer discounts, enter the price the customer actually pays after the discount, rather than the original list price.
- Enter Quantity: Use the number of units sold, measured in pieces. For a forecast, enter the number you expect to sell—not your inventory on hand.
- Read Revenue: The dollar result is price multiplied by quantity. It covers the same period as your quantity figure: monthly units produce monthly revenue, for example.
The calculator accepts one price and one quantity at a time. It does not estimate customer demand or deduct expenses.
The total revenue formula
Revenue = Price per unit × Quantity sold
In the calculator, price is p, quantity is q, and the calculation is revenue = p × q. The units cancel as follows: dollars per piece multiplied by pieces equals dollars.
Worked example
Using the calculator’s default values—a price of $19.99 and a quantity of 200,000 pieces:
Revenue = $19.99 × 200,000 = $3,998,000
If those units were sold during a year, the result would represent annual sales revenue from those units. If the quantity is only a sales target, the result is a forecast, not revenue already earned.
What does your revenue result mean?
Revenue measures the value of sales, but it does not tell you how much money the business keeps. Product costs, wages, rent, payment processing fees, and other expenses have not been subtracted. Use the Profit Calculator when you need to compare sales with costs.
Keep these distinctions in mind when interpreting the result:
- Higher revenue does not necessarily mean higher profit. Selling more units may require additional production, fulfillment, or advertising spending.
- Revenue is not the same as cash collected. Credit sales may generate revenue before customers pay, while advance payments may arrive before revenue is earned.
- The calculator does not adjust for returns, allowances, or taxes. For a net sales estimate, use figures that already reflect relevant adjustments. Exclude sales tax collected on behalf of a tax authority from your revenue price.
Compare prices and sales volumes
A useful way to apply the calculator is to test whether a lower price could be offset by higher sales volume. Consider a product normally priced at $25:
| Scenario | Unit price | Units sold | Total revenue |
|---|---|---|---|
| Original price | $25.00 | 400 | $10,000 |
| 10% discount, unchanged volume | $22.50 | 400 | $9,000 |
| 10% discount, higher volume | $22.50 | 450 | $10,125 |
You can use the Discount Calculator to find the reduced selling price before entering it here.
At $22.50 per unit, matching the original $10,000 requires $10,000 ÷ $22.50 = approximately 444.44 units. Because this example involves whole pieces, you would need to sell 445 units to reach or exceed that revenue.
That is a revenue target, not a profit target. The discounted scenario may generate more revenue but less profit because you must supply more units. The calculator also cannot tell you whether customers will actually buy the additional quantity.
How to handle multiple products or changing prices
If you sell products at different prices, calculate each product’s revenue separately and add the results:
Total revenue = (Price A × Quantity A) + (Price B × Quantity B) + …
The same approach works when a product’s price changes during the period. Avoid multiplying total units by a simple average of the prices; that can give the wrong result when sales volumes differ. Use separate calculations or a quantity-weighted average selling price.
For subscriptions, one monthly price multiplied by the number of subscriptions at that price gives a simple recurring-revenue estimate. If you have multiple plans, the Monthly Recurring Revenue Calculator is a more relevant next step.
