Introduction

This Revenue Calculator shows how much money your sales really bring in. Type in your price, how many units you sold, your discount, and your tax rate. The tool does the math right away.

You get six clear numbers: gross revenue, discounted revenue, money lost to the discount, discount impact as a percent, post-tax revenue, and effective revenue per unit. A bar and a pie chart show where each dollar goes, and a step-by-step section shows every formula used.

You can also add up to five more products or services. The calculator then adds them all together and gives you combined totals in one table. Pick from six currencies, including US dollars, euros, and pounds, and name your own unit, like "seat," "license," or "item."

Use it to check a price change, test a sale, or plan a budget. It is free, works on phones and computers, and updates as you type.

How to use our Revenue Calculator

Enter your price, how many units you sold, your discount, and your tax rate. The calculator shows your gross revenue, discounted revenue, revenue lost to the discount, post-tax revenue, and revenue per unit, plus charts and a step-by-step solution.

Currency: Pick the money type you sell in, like USD, EUR, GBP, CAD, AUD, or JPY. All results are shown in that currency.

Unit Label: Type what you sell, such as License, Seat, Item, or Hour. This name shows up in your results.

Price per Unit: Type the full price of one unit before any discount. Cents are fine.

Quantity Sold: Type how many units you sold. Use a whole number.

Discount (%): Type the percent off you gave buyers. Leave it at 0 if you sold at full price.

Tax Rate (%): Type the tax percent taken from your sales. Leave it at 0 if you pay no tax.

Add Product: Click this to add up to 5 more revenue streams. For each one, enter its own price, quantity, discount percent, and unit label to get a combined revenue total.

What Is Revenue?

Revenue is the money a business makes from selling things before any costs are taken out. The basic formula is simple: Price × Quantity = Gross Revenue. If you sell 500 licenses at $29 each, your gross revenue is $14,500.

Gross Revenue vs. Net Revenue

Gross revenue is the full amount you would make at full price. But most businesses do not keep all of it. Discounts, refunds, and sales tax cut into that number. What is left after those cuts is closer to your net revenue, the money you actually keep. Once you subtract the cost of what you sold, the Gross Profit Calculator takes the story one step further.

How Discounts Cut Into Sales

A discount lowers the price a customer pays, so it lowers your revenue too. A 10% discount means you give away 10% of your gross revenue. That gap is called revenue lost to discount. Small discounts add up fast when you sell a lot of units. Tracking this helps you see if a sale or promo is worth running.

Why Tax Matters

Sales tax is money you collect from buyers but pass on to the government. It is not profit. Taking tax out of your revenue gives you a truer picture of what your business really earns from each sale.

Revenue Per Unit

Effective revenue per unit is your discounted revenue divided by how many units you sold. It shows what each sale is really worth after discounts. If your list price is $29 but your effective revenue per unit is $26.10, discounts are costing you $2.90 on every single sale.

Multiple Revenue Streams

Most businesses sell more than one thing. A revenue stream is any source of income: a product, a service, a subscription, or an add-on. Adding them up gives you total revenue. Comparing streams side by side shows which products bring in the most money and which ones lose the most to discounts.

Why Track Revenue

  • Set prices that cover your costs and leave a profit. The Break Even Calculator shows how many units you need to sell
  • See if your discount strategy is helping or hurting
  • Plan budgets and forecast future sales
  • Find your strongest and weakest products
  • Show real numbers to lenders, partners, or investors

Remember: revenue is not profit. Profit is what is left after you also subtract costs like materials, salaries, rent, and marketing. Revenue is the top line; profit is the bottom line.


Formulas used

Gross Revenue
\text{Gross} = \text{Price} \times \text{Quantity}
Discounted Revenue
\text{Discounted} = \text{Gross} \times \left(1 - \frac{\text{Discount\%}}{100}\right)
Revenue Lost to Discount
\text{Lost} = \text{Gross} - \text{Discounted}
Discount Impact
\text{Impact\%} = \frac{\text{Lost}}{\text{Gross}} \times 100
Post-Tax Revenue and Tax Amount
\text{PostTax} = \text{Discounted} \times \left(1 - \frac{\text{Tax\%}}{100}\right), \quad \text{Tax} = \text{Discounted} - \text{PostTax}
Effective Revenue per Unit
\text{PerUnit} = \frac{\text{Discounted}}{\text{Quantity}}
Combined Totals Across Streams
\text{Total}_{X} = \sum_{i=1}^{n} X_i, \quad X \in \{\text{Gross},\ \text{Discounted},\ \text{Lost},\ \text{Tax},\ \text{PostTax},\ \text{Qty}\}
Retained vs Lost Share of Gross
\text{Keep\%} = \frac{\text{Discounted}}{\text{Gross}} \times 100, \quad \text{Lost\%} = 100 - \text{Keep\%}

Frequently asked questions

Is the tax added on top of my price or taken out of it?

It is taken out. The calculator treats your price as tax-included, then removes the tax percent from your discounted revenue. So post-tax revenue is what you keep after passing tax on to the government.

In what order are the discount and the tax applied?

The discount comes first, then tax. Here is the order:

  • Price × Quantity = Gross Revenue
  • Gross − Discount = Discounted Revenue
  • Discounted Revenue − Tax = Post-Tax Revenue

Tax is never charged on the money you gave away as a discount.

What does Discount Impact mean?

It is the share of your gross revenue you gave away. The math is Lost ÷ Gross × 100. If your discount is a flat percent, the impact matches it. When you add more products with different discounts, the combined impact is a blended number.

Why is my effective revenue per unit lower than my price?

Because of the discount. If your price is $29 and you give 10% off, each unit really brings in $26.10. The $2.90 gap is what the sale costs you on every single unit.

Why did my quantity get rounded?

Quantity must be a whole number. You cannot sell half a license or 2.4 seats. If you type a decimal, the tool rounds it to the nearest whole number and shows a note.

Does each extra product use its own tax rate?

No. One tax rate applies to every stream. Each stream can have its own price, quantity, discount, and unit label, but the tax rate is shared across all of them.

How many products can I add?

You can add up to 5 extra streams, plus your main product. That makes 6 total. The table at the bottom shows each one side by side with a combined total row.

What is the difference between gross revenue and discounted revenue?

Gross revenue is what you would earn if everyone paid full price. Discounted revenue is what you actually charged after taking the percent off. The gap between them is revenue lost to discount.

Does changing the currency convert my numbers?

No. It only changes how the numbers are shown, like the symbol and comma style. A price of 29 stays 29 whether you pick USD or EUR. Japanese yen shows no cents because yen has no decimal places.

Why is my revenue showing as zero?

Your price or quantity is blank, zero, or negative. Both must be above zero to get a result. Check for a red message under those fields.

Does this account for refunds or returns?

No. To include them, lower your quantity to only the units you kept the money on. For example, if you sold 500 and 20 came back, enter 480.

What should I put in the Unit Label box?

Whatever you sell. Common ones are Seat, License, Item, Hour, Box, or Subscription. It only changes the wording in your results, not the math.

How do I compare a sale against full price?

Run it twice. First set the discount to 0 and note the revenue. Then enter your sale discount and see the new number. The difference tells you how many extra units you need to sell to break even on the promo.
