Welcome to the CPA at Large Business Valuation Hub
Understanding what a business may be worth can help with planning, pricing, negotiations, succession, and decision-making. This page brings together tools and explainers that can help you estimate value more intelligently before deciding whether a formal valuation is necessary.
DIY valuation tools are most useful for:
rough planning, buy-sell discussions, internal strategy, exit preparation, and educational comparison.
A formal valuation may still be needed for:
litigation, estate and gift matters, shareholder disputes, tax reporting, financing, or high-stakes transactions.

How to Use This Page
- Choose your approach – try the One-Page Calculator for a quick check, then dive into the Workbook for a full DCF + multiples analysis.
- Test an app – start a free trial or questionnaire with one of the tools above; compare its output to your spreadsheet for reasonableness.
- Vet the assumptions – validate revenue forecasts, discretionary add-backs, and chosen risk premiums.
- Plan the next move – use the Exit-Readiness Checklist to shore up documents, or revisit the valuation quarterly to track growth.
A calculator can help frame the conversation. It does not replace professional judgment where the stakes are high.
Pro Tip: Run valuations under two scenarios—“baseline” and “stretch”—so you can see the upside of operational tweaks (price increases, cost cuts, recurring-revenue adds).
