A Developer's Pension Strategy: Will the National Pension Be Enough

The day I checked my projected pension

One day I looked up my projected payout on the National Pension Service website. Age 30, five years of experience as a developer, assuming I pay in until 60 based on my current salary -- the projected monthly payout was about 870,000 KRW (roughly $645).

870,000 KRW. Can you live in Seoul on that? Rent, food, phone, insurance alone exceeds 1.5 million KRW. I stared at the screen blankly for a while after seeing that number.

But will the national pension even exist by then

This is actually the more realistic worry. There's no guarantee Korea's National Pension will pay out normally in 2055 when I turn 60. I've seen news projecting the fund runs dry around 2055. (The exact year varies by article. Whether it's 2055 or 2060, the anxiety is the same.)

Sure, pension reform might happen, payout structures might change. But designing my retirement on "it'll probably be fine" requires more guts than I have.

Started looking into personal pensions

I opened an IRP (Individual Retirement Pension -- Korea's equivalent of a 401(k) or personal pension plan) last year. You can contribute up to 7 million KRW annually and get a tax deduction. The deduction alone returns about 1.15 million KRW. Clear profit, so there was no reason not to do it.

But figuring out what to buy inside the IRP was another headache. Went with a TDF (Target Date Fund) aimed at 2055 retirement. Higher equity allocation when you're young, gradually shifting to bonds as retirement approaches.

First year return was 11.3%. But that's because the market was good -- no guarantee it'll repeat.

Is there anything different because I'm a developer

Honestly, being a developer doesn't make pension strategy fundamentally different. But there's a developer-specific worry: "what if I can't work when I'm older?"

It's not like you forget how to code in your late 40s, but if your energy drops and you learn new tech more slowly, your competitiveness might decline. Switching to management is another path, but not every developer wants to be a manager.

That's why pensions feel even more important. If you assume income drops in your 50s, you need to contribute as much as possible in your 30s.

My current pension structure

National Pension: auto-deducted monthly. No choice in the matter anyway.

IRP: 7 million KRW annually. About 580,000 KRW per month.

Personal additional investment: 500,000 KRW monthly DCA. (Not technically a pension, but retirement-oriented.)

Combined, about 1.08 million KRW goes toward the future every month. Roughly 28% of my paycheck. Honestly, it's tight. But if I don't do it, I'll regret it at 60. So I push through.

My one regret is starting late

I wish I'd started the IRP at 28. Two years earlier would have meant several million KRW more at retirement thanks to compound interest. (Calculated precisely: about 3.8 million KRW difference at current return rates.)

When I was fresh out of school, I thought "pensions are a later thing." That "later" somehow became 30. If any 20-somethings are reading this, open an IRP right now. The tax deduction alone makes it worth it.

Anyway, 870,000 KRW a month won't cut it. That much is clear. The rest, I have to build myself.
