“How much should I actually invest every month?” might be the single most frequently asked question in personal finance — and it's frustrating precisely because most answers are either too vague (“invest what you can”) or too rigid (a fixed rupee number that ignores your actual salary). Here's a practical framework that scales with your income.
The 20% starting point
As a baseline, aim to invest at least 20% of your take-home salary — this aligns directly with the savings bucket in the 50-30-20 budget rule.
What that looks like at different salary levels
| Take-Home Salary | 10% (Minimum) | 20% (Recommended) | 30% (Aggressive) |
|---|---|---|---|
| ₹25,000 | ₹2,500 | ₹5,000 | ₹7,500 |
| ₹40,000 | ₹4,000 | ₹8,000 | ₹12,000 |
| ₹60,000 | ₹6,000 | ₹12,000 | ₹18,000 |
| ₹80,000 | ₹8,000 | ₹16,000 | ₹24,000 |
| ₹1,00,000 | ₹10,000 | ₹20,000 | ₹30,000 |
Which column should you actually aim for?
Use the 10% minimum if you're just starting out, paying down high-interest debt, or supporting significant family obligations. Use 20% once your budget has some breathing room — this is the sustainable target for most salaried employees. Reach for 30% only if you're deliberately accelerating toward an early goal (like FIRE) and your expenses genuinely allow it without strain.
Sequence matters: emergency fund before SIP
Before committing to any of the above, build 3-6 months of expenses as an emergency fund. Skipping this step is the most common reason SIPs get interrupted — without a cash cushion, an unexpected expense often forces you to redeem investments at exactly the wrong time, such as during a market downturn.
A worked example
Someone earning ₹60,000/month take-home, with no emergency fund yet, should direct most of their available savings toward that fund first — perhaps investing a token ₹1,000-2,000/month SIP just to build the habit — and then step up to the full 20% (₹12,000/month) once the emergency fund reaches its target. Sequencing it this way protects both goals rather than risking the SIP later.
Common mistakes to avoid
- Investing aggressively before building an emergency fund — a single job loss can then force an untimely redemption.
- Basing the percentage on gross salary instead of take-home pay, which overstates what you can actually invest.
- Never revisiting the amount after a raise — treat every increment as a chance to step up your SIP.
- Waiting for the "right" percentage instead of starting with whatever is realistic today.
Key takeaways
- 20% of take-home salary is a solid default target; 10% is an acceptable starting minimum.
- Build your emergency fund before scaling up your SIP significantly.
- Even ₹500/month is a legitimate starting point — see what is a SIP.
- Use the SIP Calculator to project what your chosen percentage grows into.
FAQs
What if I can't hit even the 10% minimum right now?
Start with whatever is realistic, even if it's ₹500/month, and increase it as your situation improves — the goal is building the habit first.
Should this percentage include my EPF/PF contributions?
You can count employer-matched PF as part of your savings rate, but it's worth having some additional flexible investments (like SIPs) that you control directly, since PF withdrawals are restricted.
How does this compare to just investing a fixed amount every month?
A percentage-based approach automatically scales with raises, whereas a flat fixed amount needs manual revisiting — see ₹5,000 vs ₹10,000 SIP over 25 years for how much that scaling can matter.
