DCF (Discounted Cash Flow) answers: "If this company keeps growing, what's the most I should pay today?"
Project future earnings
We take Duolingo's current Operating Cash Flow ($363.9M) and compound it at 15%/yr for 5 years. Growth decays by 2% each year (high growth rarely lasts forever). This growth rate is based on historical averages, and you can adjust it in the calculator.
Estimate future stock price
The projected Operating Cash Flow ($713.4M) divided by future shares (59.8M) gives us Operating Cash Flow per share. Multiply by a 25x valuation multiple = $298 stock price in 2031.
Discount to today's value
$298 in 5 years isn't worth $298 today. We discount it back at 10%/yr (your required return). We also add the present value of expected dividends over the period. Result: $185 fair entry price. This is the most you should pay today for your target return.
The Full Calculation (for the investing nerds)
Step 1: Project Operating Cash Flow
- The most recent Operating Cash Flow is $363.9M
- We project this out 5 years with 15% initial growth and 2% decay rate
- Growth decay means the growth rate shrinks each year: Year 1 grows at 15%, then the rate is multiplied by (1 - 2/100) each subsequent year
- After 5 years of decaying growth, Operating Cash Flow reaches $713.4M
Step 2: Project Diluted Shares Outstanding
- Current shares outstanding: 49.1M
- Shares change at 4%/yr (dilution increases share count)
- After 5 years: 59.8M shares
Step 3: Calculate Future Stock Price
- Formula: (Future Operating Cash Flow ÷ Future Shares) × Price Ratio
- Calculation: ($713.4M ÷ 59.8M) × 25 = $298
Step 4: Discount to Present Value
- Future stock price: $298
- Discount rate (your required return): 10%/yr
- Discounting back 5 years: $185 fair value today
DUOL trades at $153.70. Buying at that price would yield 14.2% annual return, which is above your 10% target.
