Scenario readout

Stress case can fall below contributions

This calculator is based on Korean Private School Teachers’ Pension Act rules (2026), which apply the Public Servant Pension Act: total contributions of 18% (individual 9% plus employer 9% — for teachers, school 5.294% and government 3.706%; for staff, school 9%), an accrual rate stepping down to 1.7% by 2035, a 10-year service requirement, a 36-year service cap, and a pension start age rising from 62 to 65. It is a planning estimate — confirm exact amounts with the Korea Teachers Pension (tp.or.kr).

What is the Private School Teachers’ Pension Calculator?

This tool estimates the monthly Private School Teachers’ Pension (사학연금) that a private-school employee — a teacher/professor or an administrative staff member — will receive. It also breaks down the pension’s distinctive three-party contribution structure (individual, school corporation, and government) and diagnoses the income gap (crevasse) between the retirement age and the age when the pension actually begins.

The scheme is run by the Korea Teachers Pension (사립학교교직원연금공단). Benefits are calculated by applying the Public Servant Pension Act, but who pays the contributions differs from the civil-servant pension — that is the key point this calculator makes visible.

Korea-based rules (2026). This calculator applies the Republic of Korea Private School Teachers’ Pension Act and the Public Servant Pension Act it references. Figures are planning estimates; confirm exact amounts with the Korea Teachers Pension (tp.or.kr).

The three-party contribution structure

Total contributions equal 18% of standard monthly income. The individual pays 9%(deducted from monthly pay), and the employer side covers the other 9% — but the split of that employer 9% is what separates teachers from staff.

Teacher vs. administrative staff

  • • Teacher (교원): individual 9% + school corporation 5.294% + government 3.706% = 18%. The government shares part (3.706%) of teachers’ pension financing.
  • • Administrative staff (사무직원): individual 9% + school corporation 9% + government 0% = 18%. The school corporation bears the entire employer share, with no government subsidy.

For a teacher earning KRW 5,000,000 in standard monthly income, KRW 450,000 comes from the individual, KRW 264,700 from the school, and KRW 185,300 from the government each month — so the individual pays 9% while the school and government add the rest, building KRW 900,000 (18%) toward retirement every month.

How the pension is calculated

Monthly pension = average standard monthly income × effective accrual rate
Effective accrual rate = sum of each service year’s rate (service capped at 36 years)

The average standard monthly income is the average of taxable standard monthly income across the whole service period. The accrual rate was 1.9% per year through 2015, but the 2016 reform steps it down each year — roughly 1.736% in 2026, converging to 1.7% by 2035.

Three requirements to know

  • • 10 or more years of service is required for a pension; below 10 years you receive only a lump-sum payment.
  • • The service cap is 36 years (extended from 33 by the 2016 reform); service beyond that does not raise the pension.
  • • The pension start age rises in steps by retirement year (age 62 for those retiring in 2024–2026, up to 65 from 2033). Anyone newly appointed from 2016 onward starts at 65.

The income gap (crevasse) and how to bridge it

A private-school teacher’s retirement age is 62, but the pension start age is climbing toward 65. That can leave a gap of up to 3 years with no pension income after retirement.

Two ways to fill the gap

  • • Own funds: cover the gap with an honorary retirement allowance, private pensions (IRP / pension savings), or savings.
  • • Early claim: you may start the pension up to 5 years early, but it is reduced by 5% per year (up to 25%), lowering your lifetime total.

The calculator estimates the gap length and the bridge funding needed, and compares the reduced monthly amount and lifetime loss if you claim early — so you can weigh liquidity during the gap against your lifetime total.

How to use it

Step 1: Basic information

Choose employee type (teacher or staff), gender, and current age. The contribution structure changes automatically with the employee type.

Step 2: Service information

Set the appointment (enrollment) year and the expected retirement age. The appointment year determines whether the 65-age rule for new appointees applies.

Step 3: Income

Enter the current standard monthly income and an annual growth rate for a more accurate average.

Step 4: Read the results

Review the estimated monthly pension, the three-party contribution structure, the income-gap diagnosis, and the retirement-benefit options.

Frequently asked questions

A. 9% of standard monthly income, deducted monthly. With the employer share (teacher: school 5.294% + government 3.706%; staff: school 9%), the total is 18%.

Q. Why does the accrual rate change each year?

A. The 2016 reform steps the rate down from 1.9% to 1.7% by 2035. About 1.736% applies in 2026, and each service year’s rate is summed for the pension.

Q. Are the results exact?

A. They are statutory estimates. Average income and severance depend on individual pay records, so confirm exact amounts with the Korea Teachers Pension (tp.or.kr).
