How much money will your shop bring in next year? Revenue is the top line, the total sales before any costs come out. The Revenue Calculator projects it from units sold, average price, and a returns rate.
You get gross sales, discounts, net monthly revenue, an annual figure, and daily sales. It suits store owners, freelancers who sell products, and anyone building a simple sales plan.

What the Calculator Does
Results change as you type. Three inputs produce five numbers.
- Monthly Net Sales Revenue: gross sales minus returns and discounts.
- Annualized Net Revenue: monthly net revenue times 12.
- Gross Monthly Sales: units sold times average price.
- Discounts & Allowances: the dollar amount lost to returns and discounts, shown as a negative.
- Average Daily Net Sales: monthly net revenue spread over an average month.
- Copy Revenue Projection and Reset buttons.
How to Use It, Step by Step
- Enter your expected monthly volume in Units Sold Per Month. Use whole units only.
- Enter what a typical customer pays per item in Average Price Per Unit ($).
- Enter the share of sales lost to refunds and coupons in Returns & Discounts Rate (%). The limit is 0 to 50.
- Read the large monthly figure first, then the four cards. A red message means an input needs fixing.
- Press Copy Revenue Projection to copy a text summary, or Reset to restore the sample values.
Use an average price if you sell several products. Past order data gives a better rate than a guess.
The Revenue Formulas
Revenue starts with volume times price. The discount rate then trims it down to net sales.
Units×Price-Returns & Discounts=Net Revenue
- Gross monthly sales = units × price.
- Discounts = gross monthly sales × rate ÷ 100.
- Net monthly revenue = gross monthly sales - discounts.
- Annual net revenue = net monthly revenue × 12.
- Daily net sales = net monthly revenue ÷ 30.416.
The divisor 30.416 is the average number of days in a month. A note under the daily card states it.
Worked Example
Dana sells insulated water bottles online. She expects to ship 1,800 bottles a month at an average price of $24.50. About 4% of sales are lost to returns and promo codes.
| Result | Calculation | Output |
|---|
| Gross Monthly Sales | 1,800 × $24.50 | $44,100.00 / Mo |
| Discounts & Allowances | $44,100 × 4% | -$1,764.00 / Mo |
| Net Monthly Revenue | $44,100 - $1,764 | $42,336.00 / Mo |
| Annualized Net Revenue | $42,336 × 12 | $508,032.00 / Yr |
| Average Daily Net Sales | $42,336 ÷ 30.416 | $1,391.90 / Day |
Dana can plan around $42,000 a month. That is revenue, not profit, so costs still come out of it.
How to Read the Results
Monthly Net Sales Revenue is the headline number. It is what you keep from sales after refunds and discounts.
Annualized Net Revenue is a run rate. It assumes every month matches this one. Seasonal shops should treat it as a rough guide.
Gross Monthly Sales shows what you would earn with no returns or discounts. The gap between gross and net shows how much promotions cost you.
Average Daily Net Sales helps with daily targets. It uses an average month, so it does not change with a short or long month.
From Revenue to Planning
Revenue is only the start. After costs, the gross profit calculator shows what remains once product costs are removed. The net profit calculator carries that through to the bottom line.
To see how sales are changing over time, use the revenue growth calculator. For a longer view, the sales forecast calculator projects future periods. If you have a goal in mind, work backward with the sales target calculator.
The break-even point calculator shows the sales level where losses stop. Browse more tools in the finance and business calculator hub.
Limitations and Assumptions
- The tool assumes the same units and price every month. It has no growth, seasonality, or ramp-up.
- Units must be a whole number of 0 or more. A value such as 1,800.9 or 0.5 shows a message and N/A.
- Blank fields are not changed to 0. Price must be $0 or more, and the rate must be 0% to 50%.
- Any blank, negative, or out-of-range entry shows a red message and N/A in every card.
- The copy button refuses to copy until the inputs are valid.
- The tool does not include sales tax. Leave tax out of your price so revenue is not overstated.
FAQs About the Revenue Calculator
What is the difference between gross and net revenue?
Gross revenue is total sales before any deductions. Net revenue subtracts returns, discounts, and allowances. This tool shows both.
Is revenue the same as profit?
No. Revenue is the money from sales. Profit is what remains after you pay for products, shipping, rent, and other costs.
What should I enter as the returns and discounts rate?
Divide your refunds and coupon value by gross sales over a past period. For example, $1,764 on $44,100 is 4%. Add markdowns if you run frequent sales.
How is annual revenue calculated here?
The tool multiplies net monthly revenue by 12. It does not add growth or seasonal swings. Real years usually vary from month to month.
Why is the daily figure based on 30.416 days?
A year has 365 days, so an average month has about 30.416. Using this average keeps the daily number steady in every month.
Can I use this for services instead of products?
Yes. Enter billable jobs or hours as units and your average rate as the price. The math is the same.
