Annualized Return
Formula
Total return is the full gain; CAGR is the geometric yearly rate that produces it.
Variables
| Symbol | Name | Unit | Description |
|---|---|---|---|
| PV | Present value | $ | Amount invested today |
| FV | Future value | $ | Projected value at the horizon |
| r | Annual return | % | Nominal annual return before fees/taxes |
| t | Time | years | Years invested |
| PMT | Contribution | $/period | Amount added each period |
Explanation
Total shows the whole gain; CAGR shows the yearly pace that compounds to it.
Step-by-Step Calculation
Follow each step to understand how the result is calculated from your inputs.
Total return compares end to start.
Annualize with the geometric mean over the holding period.
Worked Examples

Scenario
The portfolio return calculator run on the values above, showing the full calculation path.
Inputs
Calculation
1. Total return compares end to start. → 50.00% 2. Annualize with the geometric mean over the holding period. → 8.45%
Result
Total Return: 50.00%
Interpretation
Total 50.00% over 5 years = 8.45% annualized on $100,000 → $150,000.
Understanding Your Result
Your Result: Total Return: 50.00%
Typical range: US equities average ~10% nominal (~7% real); bonds ~4–5%; cash ~2%. Use CAGR, not simple averages, for multi-year claims.
What This Means
Total shows the whole gain; CAGR shows the yearly pace that compounds to it.
Why It Matters
Total 50.00% over 5 years = 8.45% annualized on $100,000 → $150,000.
Professional Interpretation
Total 50.00% over 5 years = 8.45% annualized on $100,000 → $150,000.
How this is calculated
Total return is the full gain; CAGR is the geometric yearly rate that produces it.
What drives the result
Each period the balance grows by the return on what is already invested, then new contributions are added. Because growth applies to an ever-larger base, results accelerate over time: the last five years of a 30-year plan typically create more wealth than the first fifteen. Fees, taxes and inflation each act as a negative compounding rate against the same base.
Recommendations
- •Quote CAGR for any multi-year result.
- •Compare against a benchmark over the same dates.
Educational Content
Introduction
Investment growth is compounding: returns earned on principal and on prior returns. One equation — future value from a lump sum plus an annuity of contributions — prices every projection on this page, which is why rate, time and contributions move all results together.
Concept Explanation
Each period the balance grows by the return on what is already invested, then new contributions are added. Because growth applies to an ever-larger base, results accelerate over time: the last five years of a 30-year plan typically create more wealth than the first fifteen. Fees, taxes and inflation each act as a negative compounding rate against the same base.
Applications
Benefits
- •Turns small regular contributions into large sums over decades
- •Rewards starting early more than any other lever
- •Gives a single math framework for goals, gaps and trade-offs
- •Makes fee and tax drag visible in dollars, not basis points
Limitations
- •Assumes a smooth constant return; real markets are volatile and sequenced
- •Ignores taxes and fees unless the mode models them explicitly
- •Single-point projections hide the distribution of outcomes
Best Practices
- •Plan at 5–7% nominal for diversified portfolios; treat higher as upside
- •Automate contributions and reinvest every distribution
- •Re-run yearly and rebalance to the target allocation
- •Evaluate spending goals in inflation-adjusted (real) terms
Common Misconceptions
Practical Tips
- •Use conservative inputs for planning and treat higher outcomes as upside.
- •Re-run yearly; plans must survive reality.
