Most Useful Tools

The five calculators people use most. Start with these.

Are these calculators accurate?

Yes — they use the same standard financial formulas used by banks and advisors. That said, every calculator is only as good as its inputs. Real-world returns vary, tax situations are personal, and projections assume consistent rates. Use these tools for planning and comparison, not as guarantees. When in doubt, consult a financial advisor for personalized guidance.

What return rate should I use in the calculators?

For a diversified stock portfolio, 7–10% nominal (before inflation) or 5–7% real (after inflation) is the historical long-term average for the S&P 500. For bonds, 3–5% is reasonable. For a blended 60/40 portfolio, 6–7% is a common planning assumption. Being conservative with assumptions is always smarter than being optimistic.

How much do I need to retire?

A common rule of thumb is 25x your annual expenses (based on the 4% withdrawal rule). If you spend $60,000 per year, you’d need roughly $1.5 million. But the right number depends on your lifestyle, location, healthcare costs, and how conservative you want to be. Our retirement calculator lets you model your specific situation with custom inputs.

What’s the difference between the DCF calculator and a full DCF model?

The calculator is a quick estimate — you plug in cash flows, a discount rate, and a growth assumption to get an approximate fair value. A full DCF model starts from revenue projections, builds out expenses, working capital, and capex, then calculates free cash flow from scratch. The calculator is useful for quick checks; the model is what analysts build for real decisions.

Do I need to create an account to use the tools?

No. Every calculator on EquityRef is free to use with no account required. Your inputs stay in your browser and are never stored or shared.
