DeFi Yield Calculator
Project DeFi earnings from principal, APY, and time horizon, including the effect of compounding.
What this calculator does
The DeFi Yield Calculator estimates your result instantly from the values you enter, using standard crypto & digital assets formulas. Project DeFi earnings from principal, APY, and time horizon, including the effect of compounding. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate for planning rather than financial advice.

About DeFi Yield Calculator
The DeFi Yield Calculator projects a dollar Principal using an APY percentage and a duration in Years. It converts the entered percentage to a decimal, raises one plus that rate to the entered number of years, and multiplies by Principal. The result area displays Final Value and Yield Earned, with Yield Earned calculated by subtracting the original Principal from the projected ending amount.
The form has no compounding-frequency selector. Its shipped equation treats the entered APY as an effective annual growth factor and holds it fixed over the entire duration, including fractional Years accepted by the numeric control. The calculator does not retrieve protocol rates, token prices, or market data, and it does not model rate changes, deposits, withdrawals, fees, liquidation, or impermanent loss. Those omissions keep the result limited to the three displayed assumptions.
Formula & Mathematical Calculation
Final Value = Principal × (1 + r)Years
Yield Earned = Final Value − Principal
Principal is the starting dollar amount. The variable r is the APY percentage entered in the form divided by 100, and Years is the duration used as the exponent. The callback applies one plus r directly, without dividing the rate by a compounding frequency, because no frequency control exists. Final Value includes the starting Principal and projected growth. Yield Earned isolates that growth by subtracting Principal. The shipped callback applies no positive-value rejection to these three fields.
Calculation Example
Example: Enter Principal of $5,000, APY of 12%, and Years of 2. The callback converts 12% to r = 0.12 and forms the annual factor 1 + 0.12 = 1.12. Raising that factor to 2 gives 1.2544. Multiplying $5,000 × 1.2544 produces $6,272, and subtracting the original $5,000 produces $1,272. The shipped result labels display Final Value: $6272 and Yield Earned: $1272. No compounding-frequency input is involved. The example assumes the entered APY remains fixed for both years and does not include protocol lookups, changing rates, token prices, additional deposits, withdrawals, fees, liquidation, or impermanent loss.
Key Benefits
- Applies an entered effective APY directly as an annual growth factor.
- Shows projected ending principal plus yield and yield alone.
- Supports fractional year inputs in the exponent.
- Keeps the fixed user-entered rate separate from protocol and market data.

Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Rates and contributions are assumed to stay constant for the whole period unless the form asks for them separately.
- Results use standard financial formulas and ignore fees, penalties and promotional terms that are not entered above.
- Inflation, tax changes and market volatility are not modelled unless a field for them is provided.
- Amounts are unit-agnostic: results are returned in the same currency you enter.
What it does not cover
- DeFi Yield Calculator produces estimates for education and planning, not a quote, offer or professional advice.
- Real-world outcomes differ when fees, taxes, rounding rules or provider-specific terms apply.
- Local regulations and tax rules vary by country and change over time; verify current rules for your jurisdiction.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For decisions with lasting financial impact, confirm the numbers with a qualified professional.
