Revenue is the total money your business brings in before any expenses

Revenue is the sum of all money a business receives from selling goods or services during a specific time period. It is not profit — profit is what remains after you subtract expenses. Revenue is the starting number on your income statement, the foundation for every other financial calculation.

The simplest formula is: Revenue = Price per Unit × Number of Units Sold. If you sell 50 widgets at $20 each, your revenue is $1,000. If you run a service business and bill $75 per hour for 40 hours of work in a week, your revenue that week is $3,000. The math does not change, but the way you count units and prices does depend on what you sell.

Key Takeaways

  • Revenue equals the price of what you sold multiplied by how many units or hours you sold, before subtracting any costs.
  • Different business types count revenue differently: product businesses count items sold, service businesses count hours or projects, subscription businesses count active subscribers.
  • You must record revenue when the sale happens, not when you receive payment, under standard accounting rules.
  • Revenue from different sources — product sales, service fees, subscriptions, one-time projects — should be tracked separately so you know which parts of your business earn the most.

The basic revenue formula for product sales

For any business that sells physical goods or digital products, the calculation is straightforward. Count the number of units sold in your time period, multiply by the price per unit, and you have revenue.

Example: A bakery sells 200 loaves of bread at $5 per loaf, 80 croissants at $3.50 each, and 150 cookies at $1.25 each in one month. The revenue is (200 × $5) + (80 × $3.50) + (150 × $1.25) = $1,000 + $280 + $187.50 = $1,467.50. If the bakery also sells wholesale bread to a restaurant for $2 per loaf and sells 100 loaves that way, add another $200 to the total. Revenue for the month is $1,667.50.

The key is to count every unit sold at its actual selling price. If you offer a discount, use the discounted price. If a customer returns an item, subtract that unit from your count. If you give away free samples, do not count them as revenue — no money changed hands.

How to calculate revenue for service businesses

Service businesses — consulting, plumbing, tutoring, graphic design — calculate revenue by multiplying the hourly rate (or project rate) by the number of hours (or projects) completed in the period.

Example: A freelance editor charges $50 per hour. In one month, she completes 60 billable hours of editing work. Her revenue is 60 × $50 = $3,000. If she also takes on a flat-fee project to edit a 300-page manuscript for $800, her total revenue for the month is $3,000 + $800 = $3,800.

The critical rule: count only hours or work you have actually completed and billed. If you spent 10 hours on a project but have not yet sent an invoice, that work counts toward revenue the moment you invoice it, not when you receive payment. Time spent on admin, marketing, or training does not count as billable revenue unless a client is paying for it.

Revenue for subscription and membership businesses

Subscription businesses — software as a service (SaaS), streaming platforms, membership sites, gyms — calculate revenue by multiplying the monthly (or annual) subscription price by the number of active subscribers.

Example: A fitness app charges $9.99 per month. At the end of one month, it has 5,000 active subscribers. Revenue for that month is 5,000 × $9.99 = $49,950. If 200 subscribers pay annually at $99 per year instead of monthly, you count their annual payment as revenue in the month they pay it, not spread across 12 months (though some accounting methods do spread it — this depends on your accounting approach).

Track the number of subscribers at the start of the period, add new subscribers, subtract cancellations, and multiply by the price. If you offer a free trial, do not count trial users as revenue until they convert to paid subscribers.

When to record revenue: the timing rule

Under standard accounting rules (accrual accounting), you record revenue when the sale is complete, not when you receive payment. This is crucial because it affects when revenue appears on your financial statements.

Example: On March 15, you invoice a client $5,000 for completed work. You record $5,000 in revenue in March, even if the client does not pay until April 20. If a customer buys a product on your website on June 10 and you ship it on June 12, you record the revenue on June 10 or 12 depending on your policy — the moment the customer has received or is may have access to to the product.

The exception is cash accounting, used by some small businesses and sole proprietors. Under cash accounting, you record revenue only when you actually receive the money. If you use cash accounting, the $5,000 invoice counts as revenue in April, not March. Check with your accountant or tax advisor about which method applies to your business.

Tracking revenue by source and category

Once you know how to calculate total revenue, break it down by source. This tells you which parts of your business are actually earning money and which are not.

Create separate line items for each revenue stream: product sales, service fees, consulting, licensing, affiliate commissions, or whatever applies to you. A software company might track revenue from new customer licenses separately from revenue from existing customer renewals. A consulting firm might separate revenue from hourly work, fixed-price projects, and retainer clients.

Track revenue by month or quarter so you can spot trends. If your service revenue is steady but product revenue dropped 30% in the last quarter, you know where to focus. If one product line brings in 60% of your revenue, you know where your business depends most heavily.

Common mistakes when computing revenue

Counting refunds as revenue. If a customer buys something for $100 and returns it for a refund, your revenue is $0 for that transaction. Subtract refunds from your total. Some businesses track this as "net revenue" — total sales minus refunds and returns.

Including sales tax or shipping fees you collected. If a customer pays $50 for a product plus $4 sales tax, your revenue is $50, not $54. Sales tax belongs to the government, not to you. Shipping fees can be trickier — if you charge the customer for shipping and keep that money, it counts as revenue. If you charge for shipping but pass it directly to the carrier, it does not.

Mixing up revenue and cash received. You can have high revenue and low cash if customers owe you money. You can have low revenue and high cash if you received a large payment for future services. These are different numbers and both matter, but they are not the same.

Forgetting to include all sales channels. If you sell through your website, a retail store, a marketplace like Amazon, and direct to wholesale customers, add all of them. Missing one channel means your revenue is understated.

Frequently Asked Questions

Is revenue the same as profit?

No. Revenue is the total money you bring in. Profit is revenue minus all your expenses — cost of goods, salaries, rent, utilities, and everything else. You can have high revenue and low profit if your expenses are high. You can have low revenue and still break even or make a small profit if your expenses are low.

Do I count revenue before or after discounts?

You count the actual price the customer paid. If you sell something for $100 but give a $20 discount, your revenue is $80. If you offer a bulk discount and sell 100 units at $8 instead of $10, your revenue is $800, not $1,000.

What if a customer pays me in advance for work I have not done yet?

Under accrual accounting, you do not record revenue until you complete the work. If a client pays $5,000 upfront for a three-month project, you record roughly $1,667 in revenue each month as you complete the work. Under cash accounting, you record the full $5,000 when you receive it. Ask your accountant which method your business should use.

How do I handle revenue from multiple currencies?

Convert all sales to your home currency using the exchange rate on the day of the sale. If you sell €500 worth of goods on a day when the euro is worth $1.10, your revenue is $550. Track the conversion rate you used so you can explain it later if needed.

Should I include revenue from returned items in my total?

No. If a customer returns an item and receives a refund, subtract that transaction from your revenue. Some businesses show this as "gross revenue" (before returns) and "net revenue" (after returns). For your actual financial picture, use net revenue.
