FAQ
What does TRA mean in this calculator?
It outputs Total Return and Annualized Return (CAGR-style), so you can see both the overall gain/loss and the per-year rate.
What’s the difference between total return and annualized return?
Total return is the overall percentage change from start to end; annualized return converts that change into an equivalent per-year compounded rate.
Can I enter days instead of years?
Yes. Leave Years empty and fill Days; the tool converts days to years using 365.25 days/year.
Why is the start value required to be greater than 0?
Return ratios and CAGR use end/start, which becomes invalid or misleading when start is 0 or negative.
Does this include dividends, deposits, or withdrawals?
No. This is a simple start-to-end return; cash flows would require an IRR/XIRR-style calculator.
How do I paste values into the quick box?
Use labels like start=1000 end=1250 years=2 or just three numbers like 1000, 1250, 2 (interpreted as start, end, years).
Is this tool offline?
Yes. It runs entirely in your browser and doesn’t send inputs anywhere.
