When we started on $1,200/month as missionaries in Taiwan, our investing bucket was just $30. It felt almost laughable. Six years later — consistent, automated, never skipped — it became $23,000+. The framework works at any income. The key is starting.

The order behind the numbers

50%

Needs first

Rent, utilities, groceries, transport. The non-negotiables. Fund these before anything else. If this bucket runs over, it tells you exactly where to look.

20%

Giving and saving second

Giving comes before wants — it’s a value, not a line item. Emergency fund sits here too. Both are non-negotiable. Both funded before you see a dollar of lifestyle spending.

20%

Other / lifestyle third

A coffee out, a day trip, personal spending. Not waste — the small things that make life enjoyable. Twenty percent sounds tight. On a missionary budget in Taiwan it actually felt generous some months.

10%

Investing last — never skipped

Yes, even on $1,200 a month. Some months it was $30. The amount mattered less than the consistency. A small amount done every month for six years looks very different from a large amount done occasionally.

About the blog

I’m Owen Liu. I started investing $30 a month on a missionary salary of $1,200 in Taiwan — the same month my wife and I got married with $200 in our account. Six years later the portfolio crossed $23,000. This blog exists to show that small, consistent financial decisions build something real — regardless of income.
