Key Takeaways
- • Simple return = (Final - Initial) / Initial × 100
- • Annualized return = ((Final/Initial)^(1/years) - 1) × 100 — enables comparison across time horizons
- • Real return = ((1+nominal)/(1+inflation) - 1) × 100 — accounts for purchasing power
- • Rule of 72: years to double ≈ 72 / annual return %
Did You Know?
How Does Rate of Return Work?
Simple Return
Measures total gain or loss: (Final - Initial) / Initial × 100. A $10,000 investment growing to $15,000 = 50% simple return.
Annualized Return
Converts total return to yearly equivalent: ((Final/Initial)^(1/years) - 1) × 100. Enables fair comparison of investments over different time periods.
Real vs Nominal
Nominal return ignores inflation. Real return = ((1+nominal)/(1+inflation) - 1) × 100. A 10% nominal return with 3% inflation ≈ 6.8% real.

Frequently Asked Questions
What is rate of return?
Rate of return measures the gain or loss on an investment relative to its cost. Simple return = (Final - Initial) / Initial × 100. A $10,000 investment growing to $15,000 = 50% return.
What is annualized return?
Annualized return converts total return to a yearly equivalent using compound growth. A 50% total return over 5 years = 8.45% annualized. This allows comparing investments of different durations.
What is real vs nominal return?
Nominal return is before inflation adjustment. Real return accounts for inflation's erosion: Real ≈ Nominal - Inflation. A 10% nominal return with 3% inflation ≈ 6.8% real return.
What is a good rate of return?
S&P 500 historical average: ~10% nominal, ~7% real. Bonds: 5-6% nominal. Savings: 2-4%. Real estate: 8-12%. Expectations should match risk tolerance and time horizon.
How do contributions affect return calculation?
Regular contributions complicate return calculation. Dollar-weighted (IRR) measures actual investor experience. Time-weighted return removes contribution timing effects.
What is the Rule of 72?
Divide 72 by your annual return to estimate doubling time. At 7% return: 72/7 ≈ 10.3 years to double. At 10%: 72/10 = 7.2 years. Quick mental math tool.
