Use a consistent reporting period and cost basis
The calculator code does not send or save entered figures. External fonts and logo assets load separately. Hosting, analytics or scripts added later have separate behaviour.
Read the assumptions below. Undefined results display as “Not available”. Positive or negative amounts need interpretation in the context of the model.
| Component | Amount |

Use reliable inputs
Keep periods, currencies and cost scope consistent. An illustrative example is not an industry benchmark.
Understand the model
Read the formula and exclusions. A balanced calculation does not independently verify the records behind it.
Protect sensitive information
Aggregate figures are enough. Do not enter personal customer, creator or employee records.
How this tool works
Calculate acquisition cost, simple contribution payback and the acquisition budget supported by your target payback period.
Formulas used
Assumptions and exclusions
Use one acquisition period and consistently attributed customers. No customer retention, cohort maturation, seasonality, cash-collection delays or discounting is modelled. Target-supported spend is arithmetic, not a recommended budget. Contribution is not revenue. Do not include sensitive customer records.
Use the tool for scenario planning and record review, not as a substitute for qualified advice or a maintained accounting system.
Frequently asked questions
Does this include lifetime value?
No. It calculates simple payback from constant monthly contribution, not lifetime value or a churn-adjusted forecast.
What assumptions should I check?
Use one acquisition period and consistently attributed customers. No customer retention, cohort maturation, seasonality, cash-collection delays or discounting is modelled. Target-supported spend is arithmetic, not a recommended budget. Contribution is not revenue. Do not include sensitive customer records.
Does currency selection apply local rules?
No. It relabels figures only, without exchange conversion or jurisdiction-specific tax, accounting, employment or licensing rules.
Are my inputs stored or transmitted?
No input transmission or persistence is implemented in the supplied calculator code. CSV export saves a copy to your device. Review unrelated website scripts separately.
Does this guarantee a business outcome?
No. Outputs depend on the entered assumptions. No staffing outcome, reconciliation accuracy, sales, funding or merchant-account approval is guaranteed.
