: Fractional CFO: Cost or Investment?
If a fractional CFO doesn’t pay for itself in about 90 days, you shouldn’t keep it. That’s a high bar, but the math is simple and fair. Here’s a practical 3-line ROI check you can run before you hire.
Three lines, one decision
- Price effect (monthly): Sales × lift% × margin ÷ 12. Even a 1% realized price improvement at typical margins can matter quickly.
- AR/interest savings (monthly): (AR-days reduction ÷ 365 × Sales) × interest rate ÷ 12. Shrinking AR > 60 not only cuts risk, it reduces financing cost.
- Debt repricing (monthly): Debt × bps relief ÷ 10,000 ÷ 12. A modest repricing can cover a meaningful share of the fee.
Decision rule
If (1)+(2)+(3) > fee, proceed. If close, right-size scope to the strongest lever. If not close, do not proceed. This keeps you disciplined and ensures the engagement is an investment, not overhead.
Inputs you send (fast)
Sales, gross margin, AR-days improvement target, current interest rate, debt balance, and the proposed monthly CFO fee. I’ll return the quick math and a recommended scope band (lite/core/intensive) that fits a payback window.
What changes over time
In early months, the wins come from pricing hygiene and AR cadence. In later months, contract durability and debt policy become material. The pattern you want is compounding predictability: better cash, lower risk, and ultimately a stronger multiple when you refinance, raise capital, or sell.
No pressure, math first
I’m happy to run the check. If it pencils, we proceed with a scoped plan. If it doesn’t, we stop—no hard feelings. Useful before billable.
