How it works
Solve an explicit cost-plus SaaS pricing scenario without confusing a margin on revenue with a markup on cost.
This is the United States planning view, with monetary inputs and outputs in USD. A currency label does not establish that a tax rate, construction price, coverage rule or legal limit has been verified locally. The inputs and limitations below describe the actual scope.
Input query strings and outputs
Use an input name in this page’s URL as ?name=value, and join additional inputs with &. Portable shared links may instead use the compact ?ac= state parameter.

Formula
required price = (fixed monthly cost/accounts + variable cost/account) ÷ (1 − payment fee fraction − target margin).
Calculations retain numeric precision internally. Displayed values are rounded for readability. Quantities that must be purchased as whole units are rounded up only where the formula explicitly requires it.
Read the inputs before calculating
- Monthly fixed service/operating cost in this scope: Enter the quantity described by the label.
- Paying accounts sharing these costs: Enter the quantity described by the label.
- Variable monthly cost per account excluding payment fees: Enter the quantity described by the label.
- Payment fee as a percentage of revenue: Enter the quantity described by the label.
- Target margin after the entered fixed/variable costs: Enter the quantity described by the label.
Reproducible worked example
The following is a fictional arithmetic example, not a local quote, a verified claimant or a market forecast. Its values are included so the formula can be checked. The form does not automatically confirm any verification checkbox.
| Input | Example value |
|---|---|
| Monthly fixed service/operating cost in this scope | 20,000 |
| Paying accounts sharing these costs | 1,000 |
| Variable monthly cost per account excluding payment fees | 5 |
| Payment fee as a percentage of revenue | 3 |
| Target margin after the entered fixed/variable costs | 30 |
| Output | Calculated result |
|---|---|
| Cost per account before percentage payment fees | USD 25 |
| Required monthly price per account | USD 37.3134 |
| Monthly revenue at entered account count | USD 37,313.4328 |
| Monthly surplus after all modeled costs | USD 11,194.0299 |
Interpreting a changed assumption
Start with one complete scenario and change only one input when diagnosing a difference. Recheck units, the period of every rate, whether an amount is recurring or one-off, and whether a cost is already included elsewhere. A larger calculated benefit is not evidence that an assumption is more likely to occur.
Limitations
- Inputs are explicit management assumptions. This is not a valuation opinion, tax filing, employment-law assessment or investment recommendation.
- Willingness to pay, competitive positioning, discounts, taxes, churn, tiers and usage distributions are not inferred. Include support and infrastructure in a scope that avoids counting the same cost twice.
Frequently asked questions
What does this SaaS Contribution Pricing result represent?
Solve an explicit cost-plus SaaS pricing scenario without confusing a margin on revenue with a markup on cost. It applies the displayed formula to your inputs; it does not infer omitted facts.
Are the starting amounts verified United States prices or legal rules?
No. Numeric defaults are illustrative unless an input or dated reference explicitly identifies a researched component. Currency is USD; local quotes, eligibility and unsupported rules must be entered and verified separately.
What must I check before relying on the result?
Inputs are explicit management assumptions. This is not a valuation opinion, tax filing, employment-law assessment or investment recommendation.
Can I compare or share different assumptions?
Change one assumption at a time and use the browser-local project or share controls. A shared URL contains the encoded input values; do not include information you do not wish to disclose.
