How to Start a SIP: A Beginner's Walkthrough

SIP Calculator Hub · Updated October 2026

Step 1: Get your KYC done

Before you can invest in any mutual fund in India, you must complete KYC (Know Your Customer) — a one-time identity verification mandated by regulators. You'll typically need your PAN card, an Aadhaar or other address proof, and a photograph. Many platforms now offer fully online (eKYC) verification in minutes.

KYC is portable: once done, it works across fund houses, so you only complete it once. You can check your status on any KYC Registration Agency's website with your PAN. "Validated" or "Registered" means you can invest; "On hold" must be fixed first, usually by updating your mobile number, email or address. We cover this in detail in the KYC guide.

Step 2: Decide how much and for how long

Before picking anything, it helps to know your goal and horizon — what you're investing for and how many years away it is. This drives how much to invest monthly. A goal calculator can back-solve the monthly amount from a target, and the SIP calculator can show what a given monthly amount may grow to.

There's no minimum that's 'right' — many funds allow SIPs from as little as ₹100–500 a month, and SEBI's Chhoti SIP lets first-time investors start at ₹250 in selected schemes. Starting small and increasing later is a perfectly reasonable path. Keep an emergency fund of a few months' expenses in a bank or liquid fund first, so you never have to stop the SIP in a crisis.

Step 3: Choose a platform and a fund category

You can invest through a fund house directly, through an online platform, or via a distributor. Direct plans carry lower costs than regular plans — a difference worth understanding before you choose, covered in the direct-vs-regular guide.

Choosing a fund is about matching the fund's mandate to your horizon and risk comfort, not chasing last year's top performer. For a first SIP with a horizon of seven years or more, many people start with a Nifty 50 index fund or a flexi cap fund. Choose the growth option rather than IDCW. The 'how to compare funds' guide walks through the factors people weigh.

Step 4: Set up the auto-debit mandate

A SIP runs on an automatic bank mandate (often called an e-NACH or OTM — One-Time Mandate) that authorises the fixed monthly debit. You register it once, linking your bank account, and the platform handles the rest each month. UPI AutoPay is another option on many apps.

Set the mandate limit higher than your current SIP so that future step-ups fit without a new mandate. Pick a debit date a day or two after your salary credit so the funds are reliably available, which avoids bounce charges. Add a nominee while you are setting up the folio.

Step 5: Start, then mostly leave it alone

Once the first instalment goes through, the most valuable thing you can do is let it run. SIPs reward consistency through both rising and falling markets. Checking the value obsessively tends to invite the very market-timing the SIP is designed to remove.

What happens after your first instalment

• Units are allotted at the NAV of the day your money reaches the fund house, if it arrives before the cut-off (3 pm for most schemes). A debit on one day can be allotted at the next day's NAV.
• You receive a confirmation by email and SMS with your folio number, the NAV and the units bought.
• A monthly consolidated account statement (CAS) from CAMS or KFintech lists every purchase across all fund houses under your PAN.
• Stamp duty of 0.005% is deducted from each instalment: ₹0.50 on ₹10,000.

Mistakes to avoid in the first year

• Judging the fund after a few months. Early SIP returns swing with the market; a negative figure in year one is normal for equity.
• Stopping in the first fall. Falls are when instalments buy the most units.
• Starting five funds at once. One or two well-chosen funds are enough to begin; more mostly adds overlap.
• Forgetting to step up. Raise the SIP with every pay rise; a 10% yearly step-up adds far more than its cost.
• Picking the regular plan by accident. Check that the scheme name says "Direct" if you are choosing funds yourself.
