Plug in your real numbers. Get back real math. This calculator shows you exactly what you're leaving on the table without a fractional CFO — unbilled work, missed tax savings, and hours wasted on books instead of building.
Quick Answer: What ROI does a fractional CFO deliver for contractors?
Most construction companies earning $500K–$10M see 3–8x return on their fractional CFO investment within 12 months. The average contractor recovers $28,000/year in unbilled work alone. Combined with tax optimization ($5K–$30K/year), eliminated bookkeeping errors, and better cash flow management, the typical total annual savings range from $40,000 to $120,000 against a $18,000–$60,000 annual cost.

A fractional CFO for construction companies typically costs $1,500–$5,000/month depending on company size and complexity. That's $18,000–$60,000/year — compared to a full-time CFO salary of $150,000–$250,000+ per year. You get the same strategic financial leadership at 70–85% less cost.
Most construction companies see 3–8x ROI from a fractional CFO within the first year. The average contractor recovers $28,000/year in unbilled work and missed change orders alone, plus additional savings from tax optimization, reduced accounting errors, and better job costing. Use the calculator above to see your specific projected ROI.
A fractional CFO saves construction companies money through five primary channels: recovering unbilled work and missed change orders (typically 2–5% of revenue), optimizing tax strategy ($5,000–$30,000/year in additional deductions), eliminating bookkeeping errors that cause overpayments, improving job costing accuracy so you stop underpricing jobs, and providing cash flow forecasting that prevents costly emergency borrowing.
For contractors earning $500K–$10M annually, a fractional CFO almost always pays for itself within 3–6 months. The smaller the company, the more likely critical financial blind spots exist that are costing real money. A $1M contractor losing just 3% to unbilled work is losing $30,000/year — more than enough to cover fractional CFO services and still come out ahead.
A bookkeeper records transactions — categorizing expenses, reconciling accounts, generating reports. A fractional CFO uses that data to make strategic decisions: identifying profit leaks, optimizing tax strategy, forecasting cash flow, improving job costing, and building financial systems that scale. Salisbury Bookkeeping provides both, so your books are clean AND your financial strategy is sound.
