You need to set aside Rp 9.686.013 per month. Start now; a five-year delay raises the number far more than it looks.

Assumptions used

  • Today's monthly expenses are inflated to retirement age, then multiplied by the needs multiplier to get the target fund.
  • A 20× multiplier assumes a 5% annual withdrawal rate; 25× assumes 4%. The longer your retirement, the larger the safe multiplier.
  • Investment returns are assumed stable throughout the period — real investments fluctuate. This figure is for planning, not a guarantee.
  • Does not include employer pensions, BPJS Ketenagakerjaan, or inheritance. Subtract those from the target if you have estimates.

How the calculation works

  1. 1Annual needs at retirement = monthly expenses × 12 × (1 + inflation)^(retirement age − current age).
  2. 2Target fund = annual needs multiplied by the multiplier.
  3. 3Existing funds are assumed to grow at the investment return until retirement age.
  4. 4The funding gap is broken down into monthly contributions using the annuity formula.

Frequently asked questions

Why does the target feel so large?+

Because living costs continue after your salary stops, while inflation has been working for 25–30 years. That's why starting earlier is much lighter: every 5-year delay typically nearly doubles the monthly contribution.

Is 20× enough?+

For a retirement of about 20 years with positive real returns, 20× is usually enough. If you have a family history of illness or want to leave an inheritance, use 25–30×.

What instruments are suitable for retirement funds?+

The most important thing is not the product name, but discipline and costs. Low-cost instruments with an age-appropriate equity allocation, plus a separate emergency fund, are usually better than expensive products that are often aggressively marketed.
