Accounting Business Valuation (Monthly) Calculator Examples
Worked examples showing how monthly revenue, costs, add-backs, and earnings multiples can produce an indicative accounting business valuation.
These examples use an annualized adjusted earnings approach. They illustrate how different revenue mixes, cost levels, and selected multiples can change an estimated value; they are estimates rather than transaction prices.

How to Read Your Results
Estimated business value is an indicative earnings-based estimate, not a confirmed sale price.
Annual adjusted earnings are the main earnings figure used in the valuation calculation.
A higher adjusted earnings margin generally means more revenue remains after normal costs, but quality of earnings also matters.
Value to monthly recurring revenue is a comparison metric, not the primary valuation formula.
Test more than one earnings multiple to understand how the selected assumption changes the estimate.
Assumptions & Important Notes
- All monthly inputs represent typical operations over a normal trading period.
- Other monthly revenue is entered as an average rather than an exceptional one-time month.
- Add-backs are valid, documented, and potentially transferable to a new owner.
- The selected multiple is appropriate for the business being modeled.

Frequently Asked Questions
Can I use an average of several months in these examples?
Yes. Using an average from a representative period can reduce the effect of an unusually strong or weak month.
Why does the project-heavy example use a lower multiple?
It is an illustrative scenario only. Less predictable revenue can be one factor that affects a multiple, but the appropriate multiple depends on many business-specific factors.
How much does a $1,000 monthly earnings increase change value?
Annualized, $1,000 per month equals $12,000 per year. At a 3.0x multiple, the simplified value change would be $36,000.
Should all examples include owner add-backs?
No. Enter add-backs only where there are genuine costs that are supportable and may not continue under a buyer.
