Formula

Total return = (end − total contributions) ÷ total contributions × 100. With no contributions, annualized = (end ÷ start)^(1/years) − 1. With contributions, annualized is approximated using average invested capital — it's a simplified estimate, not money-weighted IRR.

Example

$10,000 → $20,000 over 10 years, no contributions → total return 100%, annualized ≈ 7.18%.

How to use

  1. Leave contributions at $0 for a clean CAGR.
  2. Enter steady yearly contributions for an approximate annualized return.
  3. Compare against a benchmark (e.g. S&P 500 average) for context.

When it's useful

  • Reviewing a single investment's performance.
  • Comparing returns across years or accounts.
  • Checking whether a strategy is beating inflation.

Common examples

$10k → $20k in 10 yrs
Total return 100% · annualized ≈ 7.18%.
Add $3k/yr
Annualized uses average invested as approximation.
Loss case
Negative gain shows annualized below zero.

Frequently asked

Is annualized return the same as CAGR?

Yes — with no contributions, this is CAGR. With contributions, it's a simplified estimate using average invested capital.

Does this give an IRR?

Not exactly. True IRR is money-weighted and requires per-contribution dates. This is intentionally simple and transparent.

What if I lost money?

End value below total contributions returns a negative gain and a negative annualized rate.

Should I use real or nominal returns?

Either, as long as you're consistent. Subtract inflation for real returns — see the Inflation calculator.
