Calculator
See whether an investment actually made money and how strong the return was over time.
Who this is for
People checking how an investment performed in dollars and percentages.
What to type in
Your starting value, ending value, holding period, and any dividends received.
Start with the assumptions, then use the interpretation below to compare tradeoffs without bouncing between sections.
Market value at the end of the holding period.
Cumulative cash dividends over the holding period.
Investment check
Across 5 years, that works out to about 8.4% per year.
Initial vs. ending value
Initial investment
$10.0K
Ending value
$15.0K
50.0% total · 8.45% annualized
Total return
50.0%
Annualized return
8.4%
This compares $10,000.00 going in with $15,000.00 plus $0.00 in cash received.
Annualized return makes different holding periods easier to compare fairly.
Total return includes both price change and dividends, which is what matters for real performance.
If the annualized return is below your benchmark, compare the result against the risk you took.
Run the same math on a simple index fund before assuming the investment was worth it.
Calculators are great for scenarios. Clarity connects your real accounts so the inputs stop being assumptions and start being your actual money.
Connect a bank, brokerage, or exchange in under a minute. Read-only, encrypted, never moves money.
Use this if you want to understand how the calculator works, not just plug in numbers.

Step 2
Optionally include dividends received for total return analysis.
Step 3
Review dollar gain, total return percentage, and annualized CAGR.
These cover the assumptions, tradeoffs, and edge cases behind the calculator.
