25 LPA is the number that makes relatives assume you bought a flat and your SIP tracker says otherwise. CTC bundles employer costs you never see monthly — PF, tax on fixed pay, and variable pay you treated as salary shrink in-hand fast.
Run fixed components through a take-home calculator. At 25 LPA in a metro, old vs new regime can swing ₹50–80k a year. Pick once, automate SIP on payday, and cap rent at 30–35% of in-hand — not CTC ÷ 12.
- Fixed-heavy 25 LPA in metro: often ₹1.45–1.65L/month in-hand after PF and tax.
- Marginal tax on the last rupee often hits 30% plus cess — gross vs net gap widens here.
- ₹30–45k/month SIP is realistic if rent stays disciplined and lifestyle does not inflate on day one.
The takeaway
Never sign a lease or car EMI on variable pay. Fixed pay pays rent; bonus is upside.
