Accounting Revenue Multiple (Monthly) Formula
Learn how monthly accounting revenue, a selected multiple, debt, and surplus cash produce indicative enterprise and equity values.
This calculation estimates the indicative value of an accounting firm by applying a chosen multiple to sustainable monthly revenue. It separates enterprise value from the amount potentially available to owners after debt and surplus cash are considered.

Step-by-Step Calculation
Identify sustainable monthly revenue
Start with a representative month of recurring revenue, excluding unusual or non-repeatable billings where possible.
monthlyRevenue
Calculate annualized revenue
Multiply monthly revenue by 12 to show the annual revenue run rate for context.
monthlyRevenue * 12
Estimate enterprise value
Apply the selected monthly revenue multiple to recurring monthly revenue.
monthlyRevenue * monthlyRevenueMultiple
Adjust for debt and cash
Subtract debt and add surplus cash to convert the enterprise value estimate into an indicative equity value.
enterpriseValue - businessDebt + cashBalance
Convert to an annual revenue multiple
Divide the monthly multiple by 12 to express it as a multiple of annualized revenue.
monthlyRevenueMultiple / 12
Example: Firm with $25,000 in monthly revenue
Annualize revenue
$25,000 × 12
$300,000
Calculate enterprise value
$25,000 × 12
$300,000
Subtract business debt
$300,000 − $40,000
$260,000
Add surplus cash
$260,000 + $10,000
$270,000
Convert the multiple
12 ÷ 12
1.00x annualized revenue
Final Result
Indicative enterprise value: $300,000. Indicative equity value: $270,000.
Assumptions
- ✓Monthly revenue represents a normal, sustainable level of recurring revenue.
- ✓The selected multiple reasonably reflects the firm's retention, profitability, growth, service mix, and market conditions.
- ✓Business debt is assumed to reduce owner value in full.
- ✓Cash is treated as surplus and assumed to transfer with the business.
- ✓The stated debt and cash figures are measured consistently at the same point in time.
Limitations
- !A revenue multiple does not directly measure profitability, cash flow, or future earnings.
- !Actual transaction values may differ because of client concentration, contracts, staff retention, due diligence, and buyer demand.
- !The calculation excludes taxes, legal costs, broker fees, and other transaction costs.
- !Working-capital targets, deferred consideration, and deal-specific adjustments are not included.
- !Cash that is needed for normal operations may not be surplus cash.
Common Mistakes to Avoid
Using total revenue that includes one-off projects or unusual billings rather than sustainable recurring revenue.
Entering an annual revenue figure in the monthly revenue field.
Treating a 12x monthly revenue multiple as 12x annual revenue; it is equivalent to 1.00x annualized revenue.
Subtracting debt from revenue before applying the multiple instead of adjusting enterprise value afterward.
Adding operating cash that the business needs to continue trading as surplus cash.
Comparing estimates that use different definitions of revenue, debt, or cash.

Frequently Asked Questions
What is the formula for an accounting firm's monthly revenue multiple?
Indicative enterprise value equals monthly recurring revenue multiplied by the selected monthly revenue multiple.
How is equity value calculated from a monthly revenue multiple?
Subtract business debt from enterprise value and add any included surplus cash: equity value = enterprise value − debt + cash.
How do I convert a monthly revenue multiple to an annual revenue multiple?
Divide the monthly multiple by 12. For example, 12x monthly revenue equals 1.00x annualized revenue.
Should recurring or total monthly revenue be used?
Sustainable recurring revenue is generally the more useful input because unusual, one-off, or non-repeatable revenue can distort the estimate.
Why is debt not included in the revenue multiple formula?
The revenue multiple estimates enterprise value before the capital structure adjustment. Debt is then considered when estimating value available to owners.
Does surplus cash always increase the equity value estimate?
Only cash that is genuinely surplus and expected to transfer with the business is included in this simplified calculation.
