Discounted Cash Flow Valuation Calculator


DCF analysis values any cash-generating asset. Master discounted cash flow calculation for investment analysis.


How the Discounted Cash Flow Valuation Calculator works


Build DCF models for businesses, projects, or properties. Project cash flows, select appropriate discount rates, and calculate present values with professional techniques.

DCF is fundamental to finance. This calculator teaches the methodology while providing accurate valuations for investment decisions.

How it works

Tutorial

Discounted cash flow valuation is the most rigorous method to determine what any cash-generating asset is truly worth. Unlike market-based approaches that simply compare to similar assets, DCF forces you to think fundamentally about cash generation, growth, risk, and timing. Warren Buffett uses DCF to value every investment because it reveals intrinsic value independent of market sentiment. Whether valuing a business, rental property, or project, DCF calculation separates serious investors from amateurs.

The core insight of DCF is simple but profound: a dollar today is worth more than a dollar tomorrow because you could invest today’s dollar and earn returns. Therefore, future cash flows must be “discounted” back to present value using a discount rate that reflects risk and opportunity cost. Higher risk requires higher discount rates, which reduce present value. Understanding DCF mechanics prevents overpaying for assets and helps identify genuinely undervalued opportunities that markets misprice.

The Basic Formula

ComponentFormulaPurpose
Present ValuePV = CF / (1 + r)ⁿDiscount future cash to today’s value
NPVNPV = Σ [CFₜ / (1 + r)ᵗ] – Initial InvestmentNet value after subtracting cost
Terminal ValueTV = CFₙ × (1 + g) / (r – g)Perpetual value beyond forecast period
Enterprise ValueEV = Σ PV(CFs) + PV(Terminal Value)Total asset value

Step-by-Step Calculation

Example: Rental property generating $24,000/year net cash flow, 3% annual growth, 8% discount rate (risk-adjusted required return), 10-year holding period, $40,000 initial investment

Step 1: Project Cash Flows

YearCash Flow CalculationAnnual Cash Flow
1$24,000 × 1.03⁰$24,000
2$24,000 × 1.03¹$24,720
3$24,720 × 1.03$25,462
4$25,462 × 1.03$26,225
5$26,225 × 1.03$27,012
6-10Continue 3% growth$27,822 to $31,274

Step 2: Calculate Present Values

YearCash FlowDiscount Factor (8%)Present Value
1$24,0001/(1.08)¹ = 0.9259$22,222
2$24,7201/(1.08)² = 0.8573$21,193
3$25,4621/(1.08)³ = 0.7938$20,213
4$26,2251/(1.08)⁴ = 0.7350$19,278
5$27,0121/(1.08)⁵ = 0.6806$18,386
6-10$27,822-31,2740.6302 to 0.4632$17,535 to $14,486
Total PV (Years 1-10)Sum of all PVs$186,427

Step 3: Add Terminal Value and Calculate NPV

ComponentCalculationValue
Year 11 Cash Flow$31,274 × 1.03$32,212
Terminal Value (Perpetuity)$32,212 / (0.08 – 0.03)$644,240
PV of Terminal Value$644,240 / (1.08)¹⁰$298,422
Total Present Value$186,427 + $298,422$484,849
Less: Initial InvestmentUpfront cost-$40,000
Net Present ValueTotal PV – Investment$444,849

What This Means

This rental property investment has a massive positive NPV of $444,849, meaning it’s worth $484,849 in present value terms while only costing $40,000 to acquire. This would be an exceptional investment—in reality, market prices would likely be higher for such a property. The example illustrates DCF mechanics: even though year 1 cash flow is only $24,000, the combination of growth, time, and terminal value creates enormous wealth.

Notice that 62% of total value ($298K of $485K) comes from the terminal value—the assumed perpetual cash flows beyond year 10. This is typical in DCF models and explains why small changes in terminal growth assumptions or discount rates cause huge valuation swings. If you change the discount rate from 8% to 10%, NPV drops to $311,000—a $134K difference from a 2% rate change. DCF’s power is also its limitation: garbage inputs create garbage valuations. Always stress-test assumptions with sensitivity analysis.
