Most SIP calculators start with a target corpus and work backwards. Invest ₹10,000/month for 20 years at 12% CAGR and you'll have ₹99 lakh. Impressive on paper.
The problem is that nobody tells you where that ₹10,000 comes from on a ₹50,000 salary — after rent, EMIs, groceries, and the occasional medical bill.
This post works forwards, not backwards. Let's start with what actually lands in your account and build a realistic investment plan from there.
What ₹50,000 Gross Looks Like in Your Bank Account
Your gross salary and your take-home are two different numbers. Here's a typical breakdown for a salaried employee earning ₹50,000/month:
| Deduction | Amount |
|---|---|
| Employee PF (12% of basic, assume basic = ₹25,000) | ₹3,000 |
| Professional Tax (varies by state) | ₹200 |
| TDS (under new regime, ₹6L annual is largely tax-free after ₹75,000 standard deduction) | ₹0–₹500 |
| Estimated take-home | ₹46,000–₹46,800 |
So your working number is roughly ₹46,000–₹47,000/month. Your employer's ₹3,000 PF contribution goes into your EPF account separately — that's already a form of forced savings, which matters when we get to allocation.
A Realistic Monthly Expense Map
Your city matters enormously here. The numbers below reflect a Tier-2 city like Jaipur; adjust upward by 30–40% if you're in Mumbai or Bengaluru.
| Expense | Conservative | Moderate |
|---|---|---|
| Rent (1BHK or sharing) | ₹6,000 | ₹12,000 |
| Groceries + cooking | ₹4,000 | ₹5,500 |
| Transport (petrol/metro) | ₹2,000 | ₹3,000 |
| Utilities + phone + OTT | ₹1,500 | ₹2,000 |
| Eating out + leisure | ₹2,000 | ₹4,000 |
| Medical + personal care | ₹1,000 | ₹1,500 |
| Misc / buffer | ₹1,500 | ₹2,000 |
| Total expenses | ₹18,000 | ₹30,000 |
This leaves a monthly surplus of ₹16,000–₹28,000 before any EMIs or family obligations.
If you have an EMI — say ₹8,000–₹12,000 on a two-wheeler or personal loan — your investable surplus shrinks to ₹6,000–₹20,000.
Before You Open a SIP: Two Non-Negotiables
1. An Emergency Fund First
Before putting a single rupee into a mutual fund, build a buffer of 3–4 months of expenses in a liquid instrument — a savings account, liquid fund, or sweep-in FD. At ₹25,000/month in expenses, that's ₹75,000–₹1,00,000.
This is not optional. Without it, a hospital bill or job disruption forces you to redeem your SIP at a loss.
Set aside ₹3,000–₹5,000/month into a liquid fund until this target is met. Then redirect that amount into your SIP.
2. Term Insurance If You Have Dependents
If your parents, spouse, or siblings depend on your income, a term plan is not a future purchase. A ₹50 lakh cover for a 25-year-old costs roughly ₹500–₹700/month. Do this before increasing your SIP.
A Practical SIP Allocation Framework
Once your emergency fund is in place and insurance is sorted, here's how to think about the remaining surplus:
Scenario A — No EMIs, Tier-2 City (Surplus ~₹20,000)
| Purpose | Amount | Where |
|---|---|---|
| Emergency fund top-up / liquid fund | ₹3,000 | Liquid or overnight fund |
| Long-term equity SIP | ₹10,000 | Flexi-cap or large & mid-cap fund |
| Tax-saving (ELSS, if using old regime) | ₹5,000 | ELSS fund (3-year lock-in) |
| Short-term goal (2–3 years) | ₹2,000 | Conservative hybrid or short-duration debt fund |
Scenario B — ₹8,000 EMI, Moderate Expenses (Surplus ~₹10,000)
| Purpose | Amount | Where |
|---|---|---|
| Emergency fund (priority) | ₹3,000 | Liquid fund |
| Long-term equity SIP | ₹5,000 | Index fund or large-cap fund |
| ELSS (optional) | ₹2,000 | ELSS fund |
Scenario C — High Rent City, EMI Present (Surplus ~₹5,000–₹6,000)
At this level, a single ₹5,000 SIP into a diversified equity index fund is a perfectly sensible start. Avoid spreading ₹5,000 across 4–5 funds — it creates complexity without diversification benefit.
The right SIP amount is what you can sustain for 7–10 years without touching it. A ₹3,000 SIP you hold for a decade beats a ₹10,000 SIP you stop in 18 months.
What Your EPF Is Already Doing
Many investors forget this: your ₹3,000/month employee PF contribution (plus your employer's ₹3,000) is already building a low-risk, tax-efficient corpus at 8.25% p.a. (FY 2024–25 rate).
