Your child is a newborn. You want a university fund ready in 18 years. So you ask the obvious question: how much do I save each month?
The honest answer is "it depends on one number". That number is how fast the tuition bill grows. Pick a low one and the monthly amount looks easy. Pick a high one and it can double.
This post gives you the sums, step by step. You will see the monthly amount for three growth rates and four savings returns, so you can find your own row.
We need a starting price. Here is one with a name behind it.
Universitas Indonesia (UI) sets its tuition through Rector's Decision 297/SK/R/UI/2026. Bisnis.com reports that the highest tier of UKT (Uang Kuliah Tunggal, the single tuition fee that public universities charge each semester) for the Medical Doctor program is Rp20,000,000 per semester. We saw this figure in a search summary of the Bisnis.com report, not on UI's own page, and sources differ slightly (one shows about Rp19.8 million). Check the current UKT table of your target campus before you plan.
Why use the top of the range? Because it is the most expensive public path, which makes it a good stress test. Most majors and most fee tiers cost less.
Here is the starting point we will use:
This is NetWort arithmetic on a reported fee. It is not a quote for any one student.
Your child starts university in 18 years. Prices will not stay where they are. We test three growth rates:
| Growth per year | Where it comes from |
|---|---|
| 3.28% | Indonesia's headline inflation for September 2026, reported by BPS (via Kontan and Investortrust) |
| 5.00% | The ceiling on yearly UKT increases at public universities, set in February 2026 (see our education inflation post) |
| 8.00% | A stress case. This is a NetWort assumption, not a published statistic |
Why not use the official education inflation number? BPS's education group was up only 1.22% over 12 months to June 2026, but it averages kindergarten, tutoring and tuition together. Our earlier post explains why it is a poor guide for an 18-year tuition plan.
You may also see "education costs rise 10 to 15% a year" in the media. We could not trace that to a BPS survey, so we do not use it as a fact. The 8% case is our way to test a high outcome without claiming it is official.
The formula is simple. It is the same compounding idea as in the Rule of 72 explainer, applied to a cost.
| Growth per year | Four-year tuition in 18 years |
|---|---|
| 3.28% | about Rp286 million |
| 5.00% | about Rp385 million |
| 8.00% | about Rp639 million |
Same degree. Same campus. The bill differs by more than Rp350 million depending on one assumption.
Now the part you came for. We assume you save at the end of every month for 216 months (18 years), and the money earns a steady yearly return. The return is also an assumption. Real returns move around, and a bank deposit and a stock fund will not behave the same.
Monthly saving needed, in millions of rupiah:
| Target in 18 years | 0% return (cash) | 4% a year | 6% a year | 8% a year |
|---|---|---|---|---|
| Rp286 million (3.28% growth) | Rp1.32 | Rp0.91 | Rp0.75 | Rp0.61 |
| Rp385 million (5% growth) | Rp1.78 | Rp1.23 | Rp1.01 | Rp0.83 |
| Rp639 million (8% growth) | Rp2.96 | Rp2.04 | Rp1.68 | Rp1.37 |
Read it like this. Take the middle case: tuition grows 5% and your savings earn 6%. You need about Rp1.01 million a month. If you keep it as cash, it is about Rp1.78 million. The return you earn is worth about Rp770,000 a month in this example.
That gap is why where you keep the money matters. But a higher return also means more ups and downs, so do not assume 8% is safe.
Rp160 million is the high end. Many families will plan for less. You can scale the table directly. Half the starting cost means half the monthly saving. A Rp80 million degree at 5% growth and a 6% return needs about Rp0.51 million a month.
A few ways to make the plan easier:
The tables above use fixed returns. Real returns are bumpy. Your plan is more useful if you know how bumpy yours is.
Open your NetWort dashboard. Add the savings or fund you plan to use for this goal, then check its volatility and worst past drop. A fund that fell 30% at the wrong time can leave a gap when the first semester bill arrives. Knowing that now lets you shift to steadier money as the start date gets closer.
