Are Developer Salaries Beating Inflation?

The illusion of rising salaries

"Average developer salary hits another high" -- headlines like this appear every year.

According to Wanted's 2025 developer salary report, the average salary for a backend developer with 5 years of experience reached 65 million KRW ($48K), up 12% from 58 million KRW ($43K) in 2022.

A 12% raise sounds good, right? In my view, it's only half the story.

Over the same period, the Consumer Price Index (CPI) rose a cumulative 11%. In real purchasing power terms, salaries only went up by 1 percentage point. Just 1% over three years.

Perceived inflation runs higher than CPI

CPI is the average across an entire consumption basket. It includes items like TVs, refrigerators, and telecom fees whose prices have been flat or falling.

But isolate the major spending categories for developers and the picture looks different.

Studio apartment rents near Seoul's IT hubs rose about 25% since 2022. The Gangnam, Pangyo, and Seongsu areas were hit hardest. A Pangyo studio near the subway was 700,000 KRW ($520) per month in 2022; now it's past 900,000 KRW ($670).

Lunch has settled at a 10,000 KRW ($7.40) baseline. What cost 7,000-8,000 KRW in 2022 now routinely runs 12,000 KRW ($8.90). A cup of coffee at most cafes exceeds 5,000 KRW (~$3.70).

Lived experience tells me that a 5 million KRW salary increase feels smaller than a 200,000 KRW rent increase plus 2,000 KRW more for lunch plus 500 KRW more for coffee.

Annualized: 2.4 million KRW in higher rent, about 500,000 KRW in higher lunch costs, roughly 120,000 KRW in higher coffee costs. That alone totals 3 million KRW. Living cost increases nearly wipe out the salary bump.

Different stories at different levels

Overall averages are meaningless. Break it down by seniority and completely different pictures emerge.

Juniors (1-3 years) saw average salaries rise from 42 million KRW to 45 million KRW -- a 7% increase. Well below inflation. Junior developers' real purchasing power actually declined.

Seniors (7+ years) fared better. Salaries rose from 75 million to 85 million KRW -- about 13%. Barely clearing the inflation hurdle.

The biggest gains went to AI/ML engineers, who command a 20-30% salary premium at equivalent experience levels. With AI talent demand far outstripping supply, two developers with the same 5 years of experience can see salaries diverge by 20 million KRW or more depending on whether they have AI experience.

But in practice

People say "IT is still a high-paying field," but in reality, the gap with other industries is narrowing.

In 2020, average developer salaries were about 1.6 times the overall occupational average. By 2025, that ratio had shrunk to 1.4x. Other fields' wages have been rising too, closing the gap.

Finance and consulting, in particular, saw faster salary growth than IT.

Developers still earn above average, certainly. But the formula "developer equals guaranteed high salary" is weakening.

Especially at the junior level, the gap with white-collar office jobs is nearly gone. A fresh hire at a large Korean conglomerate's office position can match or even out-earn a junior developer at a small-to-mid IT company. "Learn to code and you'll make good money" now needs an asterisk.

Protecting real purchasing power

Negotiating salary well matters, but there are limits.

After seven years in the IT industry, what I've realized is that "income beyond salary" determines real purchasing power more than salary itself.

Side project revenue, consulting and lectures through tech blogging, stock options, investment returns. It's becoming harder to beat inflation with base salary alone.

Ultimately, developers need to move past the equation "salary = income." It's an era that demands strategies for monetizing your skills through multiple channels.

One more thing: managing expenses matters just as much as growing income. Monthly SaaS subscriptions, a gym membership you barely use, habitual coffee purchases.

Small expenditures add up and easily consume your salary increase.

In the end, there are three things developers need to do in an inflationary era: negotiate salary consistently, build side income channels, and cut unnecessary spending.

The gap in real purchasing power between developers who do all three and those who only watch their salary becomes stark within three years.
