27 LPA is where SIP finally feels serious — and lifestyle inflation kills it fastest. On fixed-heavy metro packages, in-hand often lands ₹1.6–1.8L/month. After rent at 30–35%, you still have headroom for ₹50–68k SIP if you automate on payday.
SIP math on 27 LPA in-hand
Do not SIP on CTC ÷ 12. Run fixed pay through a take-home calculator, subtract rent and essentials, then target 15–20% of in-hand for equity SIP. At ₹1.7L in-hand, that is ₹28–34k/month — enough to build ₹1 crore over 12–15 years at 12% CAGR if you step up on raises.
- Fixed-heavy 27 LPA metro in-hand: often ₹1.6–1.8L/month after PF and tax.
- Conservative SIP: ₹40–50k/month if rent is controlled.
- Aggressive SIP: ₹58–68k/month if you cap rent at 30% and skip lifestyle upgrades.
The takeaway
Automate SIP on payday before rent and UPI spends. Step up 10% every raise — that beats trying to time the market.
