SIP

Full form: Systematic Investment Plan

Investments

SIP is a method of investing a fixed amount in a mutual fund at regular intervals -- typically monthly. Each instalment buys fund units at that day's NAV. SIP enforces investment discipline, benefits from rupee cost averaging, and harnesses long-term compounding without requiring market timing.

In detail

SIP is not a product -- it is a method of investing in any mutual fund. The same fund can be invested in via lumpsum or SIP. SIP advantages: no need to time the market (you buy at different NAVs across market cycles), automatic investment discipline (auto-debit on salary credit date), and flexibility (pause, stop, increase anytime).

Rupee cost averaging: when markets fall, your fixed SIP amount buys more units at lower NAV. When markets rise, you accumulate fewer units at higher NAV. Over time, average cost per unit is lower than average NAV -- this mathematical benefit is rupee cost averaging.

SIP amounts in India crossed Rs 20,000 crore monthly in 2024, with over 7 crore active SIP accounts.

Formula

Future Value = P x [(1+r)^n - 1] / r x (1+r) P = Monthly investment, r = Monthly rate, n = Months Wealth gained = FV - (P x n) Example: Rs 10,000/month at 12% for 15 years: FV = Rs 49.9L, Invested = Rs 18L, Gains = Rs 31.9L

Real-life example

🇮🇳 India example

Meera started a Rs 5,000/month SIP in a Nifty 50 index fund in January 2010. By January 2025 (15 years, 180 instalments), she invested Rs 9 lakh. At approximately 13% CAGR over this period, her portfolio is worth approximately Rs 28 lakh. She never worried about market timing -- the SIP bought more units during the 2011, 2015, 2018, and 2020 corrections automatically.

Frequently asked questions

What is the minimum SIP amount?
Most AMCs and platforms allow SIP from Rs 100-500/month. There is no practical maximum. For tax-saving ELSS: Rs 500/month minimum typically. The right amount is whatever you can commit to consistently -- starting with Rs 500 today beats waiting to start with Rs 5,000 someday.
Can I stop a SIP anytime?
Yes. SIP can be paused (typically for 1-6 months) or permanently stopped with 30 days' notice on most platforms. Stopping does not force redemption -- your existing units continue to earn returns. The earlier you stop, the more compounding benefit you lose.
