What is SIP XIRR?

XIRR (Extended Internal Rate of Return) is the most accurate way to measure your SIP returns. Unlike CAGR or absolute returns, XIRR accounts for:

💡 Simple Explanation

XIRR tells you: "If I had invested all this money at once and earned a fixed annual return, what rate would give me the same final value?" It's like converting your messy SIP history into one clean annual percentage.

Why Your AMC App Shows Different Returns

Mutual fund apps often show absolute returns or CAGR, but neither accounts for when you invested. Here's the difference:

Absolute Return

Total profit as % of invested — ignores time completely

CAGR

Assumes lump sum at start — wrong for SIP

XIRR ✓

Accounts for each SIP date — the true answer

What is Step-Up SIP?

A step-up SIP (or top-up SIP) means you increase your SIP amount every year — typically by 10-15% to match salary increments. Our calculator handles this automatically.

Example: Step-Up SIP

Year Monthly SIP
2023 ₹5,000
2024 ₹5,500 (+10%)
2025 ₹6,050 (+10%)

Compare Your SIP Returns with FD

Our calculator shows you what your money would have grown to if you'd invested in a Fixed Deposit at 7% p.a. instead. This helps you understand if your mutual fund is actually beating inflation and safe alternatives.

✅ Good Benchmark

If your SIP XIRR is above 12%, you're likely beating most FDs and inflation-adjusted returns. Below 7%? Consider reviewing your fund selection.
