A free SaaS gross margin calculator that turns revenue and cost of goods sold into a gross margin percentage. Enter both and see your margin plus how it stacks up against the 70 to 80 percent that healthy SaaS runs.
This calculator runs entirely in your browser. Nothing you enter is sent anywhere or stored. It is a quick estimate, not financial advice.
Gross margin is what separates software economics from everything else. It is the money left to fund growth after the cost of delivering the product. A 78 percent margin means 78 cents of every revenue dollar can go to sales, R&D and profit. Drop to 50 percent and you are running a services business wearing a SaaS badge and investors will price you like one.
The honest figure depends entirely on what you load into COGS. Hosting, support and payment fees belong there. Sales salaries and office rent do not. The common mistake is dumping too much into COGS and panicking or too little and flattering the number. Put true cost of delivery in COGS and the margin you get is the one valuation runs on.
Use revenue for the period you are measuring. Recognised revenue, not bookings or cash collected, so the margin reflects the business as it actually runs.
Add up cost of delivery only: hosting, infrastructure, customer support, payment processing and third-party software baked into the product. Leave sales and overhead out.
Subtract COGS from revenue, divide by revenue and multiply by 100. Compare it to the 70 to 80 percent band where healthy SaaS sits.
A SaaS gross margin calculator works out the percentage of revenue left after the cost of delivering your product. It subtracts COGS from revenue and divides by revenue. The result tells you how much of every dollar is available to fund growth and profit, which is the single biggest reason software gets valued higher than services.
Subtract cost of goods sold from revenue, divide by revenue and multiply by 100. The formula is trivial. The judgement is in COGS: include hosting, support, payment fees and product-embedded third-party costs. Keep sales, marketing and general overhead out. Those belong below the gross margin line, not inside it.
Healthy SaaS runs a 70 to 80 percent gross margin and the best products clear 80. Under 70 usually points to heavy support, expensive infrastructure or pass-through costs. Under 50 means the model is not really software economics yet. Margin is the lever that decides how much growth you can fund from each dollar so it is worth defending.
COGS is the cost of delivering the product to paying customers. That means cloud hosting and infrastructure, customer support and success tied to delivery, payment processing fees and any third-party software embedded in what you sell. It does not include sales salaries, marketing spend, R&D or office costs. Those sit below gross margin as operating expenses.
Gross margin sets how much of each revenue dollar can become growth or profit, so it drives the multiple investors will pay. A high-margin business converts revenue into reinvestment far more efficiently than a low-margin one. Two companies with identical revenue and growth can be valued very differently once margin is in the picture, because one simply has more fuel.
If your gross margin is dragging the model and the valuation with it, the fix usually starts upstream in how you acquire and serve. Book a 30-minute audit and we will tell you which lever moves first. No sales sequence.
