Planning EMI + SIP so both fit one salary
One take-home, two automatic debits
A home or car EMI is non-negotiable once sanctioned. An SIP feels optional until you care about the goal. If you size them in separate mental buckets, rent day is when something bounces. Build one monthly stack: take-home, then rent/society, EMIs, insurance, SIP, then lifestyle.
Stress the month before you raise either
Put the proposed EMI in the EMI calculator and the proposed SIP in the SIP calculator. Add them to fixed costs and ask whether a smaller bonus month still works. A common pattern is to keep total EMIs near a comfort band of take-home and fund SIPs only from what remains after a small buffer transfer.
If something must give, choose on purpose
Cutting the SIP beats missing an EMI. Stretching the loan tenure to “make room” for a large SIP can raise lifetime interest more than the SIP earns in a dull decade. Revisit the pair after every rate reset or salary change instead of locking both at the approval-day maximum.
