Two prices. One exponent.
CAGR is (end/start)^(1/n) − 1. Mutual-fund “CAGR since inception” on a SIP is often a marketing cousin of XIRR. If you put money in more than once, this page is the wrong one.
Worked example: ₹1 lakh → ₹2.1 lakh in 6 years
(2.1)^(1/6) − 1 ≈ 13.2%. That is not “13% every calendar year.”
Questions
Are my numbers uploaded?
No. Arithmetic stays in this tab. Remember writes this browser only.
Can I share the inputs?
The URL hash (#) stores fields. Copy the address bar. Nothing is sent as a query string to a server of ours.
Is this a filing?
No. Print the worksheet. Argue with payroll or a CA. Do not paste this into an ITR as authority.
SIP CAGR?
If you added money, use XIRR. CAGR assumes one start value and one end value.
