DCF Calculator

What this calculator does

This DCF calculator estimates the present value of future cash flows and a terminal value using a discount rate and long-run growth assumption.

DCF is one of the most useful valuation frameworks because it forces assumptions about cash generation, timing, and required return into a single structured model.

It is also highly sensitive to inputs, so the real value of the calculator is often in scenario testing rather than in one precise-looking output.

This page is built for users who need a defensible planning answer, not just quick arithmetic. It translates "Year 1 cash flow", "Annual cash flow growth", and "Discount rate" into "DCF value", "Terminal value", and "Discounted terminal value" so the trade-off is visible in one place instead of being hidden behind a single number.

How to use the dcf calculator

1. Enter the expected first-year cash flow, forecast growth rate, discount rate, terminal growth rate, and projection horizon.
2. Check the discounted terminal value carefully because terminal assumptions can dominate the final valuation.
3. Compare multiple scenarios instead of relying on a single base case.
4. Start with "Year 1 cash flow", "Annual cash flow growth", and "Discount rate", then check whether the first output cards already answer your question. After that, add advanced assumptions such as "Terminal growth rate" only when they are real enough to change the decision.

Formula and methodology

Cash flows are projected forward each year using the growth assumption, then discounted back to present value using the discount rate.

Terminal value is estimated using a Gordon-growth style perpetuity formula after the explicit forecast period.

The calculator requires the discount rate to exceed the terminal growth rate so the valuation remains mathematically stable.

The model maps "Year 1 cash flow", "Annual cash flow growth", and "Discount rate" into "DCF value", "Terminal value", and "Discounted terminal value" using the formulas shown on the page. Keeping those relationships visible makes it easier to separate the core economics from the optional adjustments and to understand which assumption is actually moving the answer.

Worked example and practical context

A business with strong near-term cash flow growth can still produce a modest DCF value if the discount rate is high or the terminal assumption is conservative.

That is why valuation work should focus as much on assumptions and ranges as on the headline result.

How to interpret the results

DCF value is the present value implied by your assumptions, not an objective market truth.

If discounted terminal value is most of the enterprise value, the model may be highly sensitive and worth stress testing further.

Read "DCF value" first, then use the other summary cards, the chart, and the detailed table to judge cash flow today and value creation over time. In most finance decisions, the best option is the one that stays strong across the full picture, not just the one with the most attractive first number.

Common mistakes to avoid

• Using a terminal growth rate that is too high relative to the discount rate.
• Treating a DCF output as precise despite highly uncertain assumptions.
• Ignoring how sensitive the model is to small changes in discount rate or terminal growth.

Key terms
