How-to SIP amount goal-based

How to set your SIP amount from goals (mutual fund)

From WebNotes, a public knowledge base. Last updated . Reading time ~5 min.

Setting the right SIP amount is the bridge between abstract financial goals and concrete monthly action. Most retail investors either pick an arbitrary number (Rs 5,000 because it sounds reasonable) or under-shoot because they don’t inflation-adjust the target.

Step-by-step procedure

See the procedure infobox above.

Worked example: retirement at 60

  • Current age: 30.
  • Years to retirement: 30.
  • Target corpus (in today’s value): Rs 5 crore.
  • Inflation: 6%.
  • Inflation-adjusted target: Rs 5 crore × (1.06)^30 ≈ Rs 28.7 crore.
  • Expected return (equity-heavy SIP): 12%.
  • Required SIP: ~Rs 80,000/month.

If Rs 80,000 is unaffordable: extend horizon (35 instead of 30 years), accept lower corpus, or use step-up SIP starting lower and increasing 10% annually.

Worked example: child UG education

  • Current child age: 2.
  • Education starts: 16 years from now.
  • Target corpus today: Rs 50 lakh.
  • Inflation (education-specific, ~8%): Rs 50L × (1.08)^16 ≈ Rs 1.71 crore.
  • Expected return (equity-heavy for 16 years): 11%.
  • Required SIP: ~Rs 25,000/month.

Step-up SIP

Most platforms allow step-up (annual percentage increase). If your salary grows 8-10% annually, an 8% step-up SIP keeps the SIP-to-income ratio constant.

Example: starting SIP Rs 15,000/month with 10% step-up reaches:

  • Year 5: ~Rs 22,000/month.
  • Year 10: ~Rs 35,000/month.
  • Year 20: ~Rs 90,000/month.

This dramatically eases the initial commitment.

Multiple goals, multiple SIPs

You don’t need to lump all goals into one SIP. Use:

  • One SIP for retirement → equity-heavy fund.
  • One SIP for child education → equity-heavy fund (separate scheme for tracking).
  • One SIP for house in 5 years → hybrid or conservative balanced advantage.
  • One SIP for emergency corpus → liquid fund .

Folio-level segregation helps tracking; tax treatment is per scheme regardless.

Plan with the “realistic” column. Track against actual periodically.
