How to calculate a SaaS subscription price
Estimate a monthly SaaS price from fixed costs, per-customer costs, target customers, profit margin, and payment fees.

Open the matching ToolBento utility →Price from costs before guessing
A SaaS price feels easier to invent than to calculate, but a guess can hide whether the plan actually covers hosting, support, software, payroll, and payment fees. A simple pricing calculation gives you a baseline monthly price per customer before you layer on positioning, competitors, discounts, or annual plans.
Separate fixed and variable costs
Start by splitting costs into two buckets. Monthly fixed costs are the expenses that stay roughly the same even if one more customer signs up, such as salaries, rent, core hosting, software subscriptions, and support overhead. Variable cost per customer is the extra monthly cost to serve one account, such as usage-based infrastructure, AI credits, storage, email volume, or account-level support time.
What to enter in ToolBento
Open ToolBento's SaaS Pricing Calculator and fill in the plain-language fields. Monthly fixed costs is your total recurring cost base for the scenario. Variable cost per customer is the monthly cost for one paying customer. Target customers is the number of customers you expect at this pricing stage. Target profit margin is the margin percentage you want after costs and payment fees. Payment fee percent is the processor percentage to include, and Currency is only the code shown in the result, such as USD, EUR, GBP, or KRW.
Use Calculate price for the baseline
After the numbers look reasonable, press Calculate price. The tool returns a suggested monthly price per customer, then shows the revenue summary: target customers, monthly revenue, payment fees, fixed costs, variable costs, estimated profit, estimated margin, and the assumptions used for fixed cost per customer, variable cost per customer, and target profit margin.
Change the customer count to see scale effects
Customer count has a big effect because fixed costs are spread across the customers in the scenario. If you enter 100 customers, the fixed cost per customer may be high. If you enter 1,000, the same fixed costs are spread much thinner. Run Calculate price a few times with conservative, expected, and optimistic customer counts so you can see when a price only works at scale.
Do not treat margin as the whole strategy
The calculator gives a cost-based price, not a complete pricing strategy. You still need to consider customer willingness to pay, competitor pricing, sales motion, onboarding cost, churn risk, free trials, support load, and whether your product saves enough time or money to justify the number. Use the calculated price as a floor or sanity check, then compare it with the market.
Common SaaS pricing mistakes
Do not leave out payment processing fees if your margins are tight, and do not pretend every user is a low-usage customer if a few heavy accounts drive infrastructure cost. Also avoid setting a low launch price without a path to profitable renewals. If the baseline price feels too high, revisit the cost structure, target segment, package limits, or customer volume instead of simply deleting costs from the calculation.
