How to Calculate Annual Return on Investment

The simplest version: take the year's percentage gain (including reinvested dividends) and that's your annual return. Examples, pitfalls, and how annual differs from annualized.

The Formula

Annual Return = (End of Year Value − Start of Year Value + Distributions) / Start of Year Value × 100

Annual return measures the percentage gain during a single calendar year. It's the most common number you see quoted (e.g., 'the S&P 500 returned 26% in 2023'). Simple to calculate, but volatile year-to-year.

When to Use Annual Return

  • Comparing year-over-year performance
  • Tax-loss harvesting decisions (compare to current year)
  • Reading fund fact sheets and benchmarks
  • Quick performance check on a single year

Worked Examples

Example: S&P 500 in 2023

Given
  • S&P 500 close Dec 30, 2022: 3,839
  • S&P 500 close Dec 29, 2023: 4,769
  • Dividends paid during 2023: ~1.5% of starting value
Calculation
  1. Price return: (4,769 − 3,839) / 3,839 = 24.2%
  2. Dividend return: 1.5%
  3. Total annual return: 24.2% + 1.5% = 25.7%
Result
Annual return 2023 = ~25.7%
💡 Reported '26% return' in news headlines refers to this. Note: this is one year. S&P averages ~10% annually over long periods — 2023 was a strong year.

Common Pitfalls to Avoid

Pitfall 1: Using only price return

S&P 500 returned 25.7% in 2023 but the price-only return was 24.2%. Stocks like REITs returned 11% price but 15%+ total. Always include distributions.

Fix: Look at 'total return' numbers, not just price. Most financial sites report both. Use total return for accurate comparisons.

Pitfall 2: Cherry-picking years

S&P returned +26% in 2023. S&P returned −18% in 2022. Picking the good year and ignoring the bad year is misleading.

Fix: Always look at multi-year returns (3, 5, 10 years) for context. Single-year returns are noisy.

Frequently Asked Questions

What's a good annual return?

For a diversified US stock portfolio, 7-10% per year is historically average. Anything above 12% is excellent; below 4% is poor. For bonds, 3-5% is normal. Cash equivalents (savings, CDs, T-bills): 1-5% in current rates.

Is annual return the same as CAGR?

No. Annual return is for ONE year. CAGR is the average annualized return over MULTIPLE years. You can have annual returns of +30%, −15%, +20% — averaging to 11.67% per year, but CAGR of 10.16% per year. CAGR is the more useful multi-year metric.

What was the S&P 500's average annual return?

Since 1928, the S&P 500 has averaged about 10% per year (with dividends reinvested). Adjusted for inflation, that's about 7% real return. Recent decades: 1990s ~15%/yr, 2000s ~0%/yr (including two crashes), 2010s ~14%/yr.
