Revenue Calculator

Revenue is just price times quantity, but the math hides three useful questions. What will you bring in if you sell 500 units at $20? What price do you need to hit a $50,000 target? How many units do you need to move at $15 each to clear $12,000? This calculator answers any of the three when you give it the other two.

What is revenue?

Revenue is the total money a business takes in from selling goods or services in a given period, before you subtract anything. It sits at the top of the income statement, which is why people call it "top-line." Profit is what's left after costs come out, so the two numbers diverge fast. A company can pull in $1 million in revenue and still walk away with $100,000 in profit once materials, payroll, and rent are paid. That's why revenue forecasts are a planning anchor: they tell you how big the pie is before you start cutting it.

How to use this calculator

Type in any two of the three values and the third fills itself in.

• Price $15, quantity 800 gives a revenue of $12,000.

• A $50,000 revenue target across 1,000 units works out to $50 per unit.

• Need $9,000 at $30 each? You're looking at 300 units to move.

It works for any model where money in equals unit price times unit count. For a service business, that's clients multiplied by the average ticket. For subscriptions, subscribers times the monthly fee. For retail, run it per product line and add the lines together; a blended figure hides which SKUs are actually pulling weight.

Applications

Most use cases come down to either projecting forward or sanity-checking after the fact. A sales team stress-tests a quarterly quota by asking what the team needs to sell at the current close rate and average deal size. A marketing team backs out campaign revenue from conversion rates and average order value. Founders building investor decks run the same equation a dozen ways with different prices, different volumes, different mixes, looking for the curve that supports the story they want to tell.

Pricing decisions live here too. A $5 price increase that costs you 10% of volume is a very different conversation from one that costs you 30%, and the easiest way to see the difference is to run the numbers both ways before the meeting.

Tips for accurate revenue calculations

• Match the time periods on both sides. Monthly price multiplied by annual quantity gives a meaningless number.

• Use the net price the customer actually paid, not the list price you publish.

• For subscription products, decide upfront whether you're modeling gross MRR or churn-adjusted MRR; they aren't the same number.

• Split product lines apart before you add them back up. A blended revenue figure hides which products are doing the work.

Frequently asked questions

What's the difference between revenue and profit?

Revenue is what comes in. Profit is what stays after everything you paid to make and sell the thing. Big revenue paired with small profit usually means costs are high, not that sales are bad.

How do I calculate revenue for a service business?

Multiply your average ticket by the number of clients served in the period. Fifty clients at $100 each gives you $5,000. If your prices vary a lot across packages, calculate each tier on its own and sum them rather than averaging.

Can I use this for subscription revenue?

Yes. Plug subscriber count in as quantity and the subscription price in as unit price. Stay consistent on the time window: monthly subscribers times the monthly fee gives you MRR, and annualizing both sides gives you ARR.

When should I separate gross revenue from net revenue?

Whenever refunds, discounts, or sales tax move the number enough to matter. For a low-return digital product, gross is usually fine. For apparel with 25% returns, the gross figure will mislead you every time.
