Step-Up SIP

Investments

A Step-Up SIP (also called Top-Up SIP) automatically increases the monthly SIP amount at regular intervals -- typically annually -- by a fixed amount or percentage. It aligns investment growth with income growth and dramatically improves long-term corpus.

In detail

Step-up SIP vs regular SIP (12% CAGR, 20 years):nFlat SIP Rs 10,000/month: corpus approximately Rs 99.9LnStep-up SIP Rs 10,000/month, 10% annual increase: corpus approximately Rs 1.88 CrnDifference: Rs 88L extra by simply increasing Rs 1,000/month each yearnnPractical rule: if salary grows 10-15% annually, step up SIP by 5-10% annually. The SIP amount remains a decreasing percentage of income, making it psychologically sustainable while mathematically powerful.nnAll major fund platforms support step-up SIP: Groww, Zerodha Coin, Kuvera, Paytm Money.

Formula

Frequently asked questions

Should I always choose step-up SIP over flat SIP?
Yes if your income grows annually -- which it almost always does. Even 5% annual step-up dramatically improves outcomes. The only reason to choose flat SIP: if income is highly variable (business income, freelancing) and you cannot commit to increasing amounts.
