Step-Up SIP: Why a 10% Annual Increase Changes Everything
By Nitish Bharadwaj · Published May 26, 2026 · 4 min
A step-up SIP increases the monthly investment amount by a fixed percentage — typically 10% — each year, aligned with income growth. Over 15 years, a ₹10,000 SIP with a 10% annual step-up grows to roughly 1.6 times the corpus of a flat ₹10,000 SIP at the same return rate. This article explains the compounding mechanics, shows the corpus difference across 10, 15, and 20-year horizons, and explains how to set up a step-up SIP on major mutual fund platforms.
A step-up SIP means increasing your monthly SIP amount every year — usually by 10–15%. It matches your growing income and dramatically accelerates wealth creation — putting a ₹1 crore corpus within reach years earlier than a fixed SIP — without requiring a large upfront commitment.
| Strategy | Final Corpus | Total Invested | Wealth Ratio |
|---|---|---|---|
| Regular SIP (fixed ₹5,000) | ₹49.9L | ₹12L | 4.2× |
| 10% Step-Up | ₹98.5L | ₹34.4L | 2.9× |
| 15% Step-Up | ₹1.50Cr | ₹61.5L | 2.4× |
How to Enable Step-Up SIP
Most AMCs and apps (Zerodha Coin, Groww, Kuvera) offer a step-up SIP option. You set the base amount (say ₹5,000), the annual increment (say 10% or ₹500 absolute), and the increment date (usually April to align with salary hikes). It's automated — you don't need to manually increase each year.
Behavioural Advantage
The step-up SIP aligns with Parkinson's Law of lifestyle inflation — people tend to spend what they earn. Automating a step-up means the increment goes to investments before it can be absorbed by lifestyle. Start with whatever you can afford — ₹1,000/month in a Nifty 50 index fund is better than waiting until you can invest ₹10,000.
