Key takeaways
- DCF valuation is most useful when future cash flow can be estimated with reasonable discipline.
- Growth, margin, WACC, terminal value, capex, and working capital assumptions can move value sharply.
- Sensitivity analysis is essential because small assumption changes can create large valuation differences.
What a DCF model is trying to answer
A DCF model asks what future cash flows are worth today. For SMEs, the answer depends heavily on revenue growth, margin stability, reinvestment needs, discount rate, and terminal assumptions.
The assumptions that matter most
The most sensitive inputs are often revenue growth, EBITDA margin, working capital, capital expenditure, WACC, and terminal growth. Small changes in these assumptions can materially shift value.
Why sensitivity analysis is important
Sensitivity analysis shows how value changes when key assumptions move. It is especially important for SMEs because historical results may not fully represent future risk.
Decision workflow
How to use this in a real review
Build a base forecast from revenue, margin, reinvestment, and working capital assumptions.
Select a discount rate and terminal value method that reflect the risk of the business.
Review sensitivity cases before relying on the valuation output in a negotiation or investment memo.
How to apply it
Practical review checklist
- Start from realistic revenue and margin assumptions rather than optimistic targets.
- Separate operating performance from financing structure so enterprise value is not distorted.
- Run low, base, and high cases before presenting the result to a buyer, investor, or lender.
Review risks
Common mistakes to avoid
- Forecasting aggressive growth without explaining how the business will fund it.
- Treating terminal value as a plug number rather than a major driver of enterprise value.
- Using one discount rate without considering the risk profile of the specific company and country.
