1. The Large Sum Most Workers Don't Know They Have
Every month you work under Social Security Section 33, 3% of your salary is automatically deducted, and your employer matches with another 3%. These 6% are your guaranteed old-age savings. Although the government is obligated to contribute 2.75%, it currently has outstanding arrears running into tens of billions of baht. Any allocation to individual accounts depends on Cabinet resolutions issued periodically — not automatic. This government portion is only credited to those who receive the lump-sum gratuity (บำเหน็จ), determined automatically by months contributed (under 180 months). Those who receive the monthly pension (180+ months) do not receive this portion.
When you turn 55 and leave employment, the fund pays it all back as your Old-Age Gratuity (Bamnet Charabhap). The problem: most workers don't know how much they'll receive, or whether to take it as a lump sum or as a monthly pension for life.
"Old-age money is our money, not the government's. I am committed to changing the law so you have the genuine right to choose, withdraw, and borrow it."

Most online calculators use a single average interest rate across all 28 years — which can produce errors of tens of thousands of baht. The reality: the Social Security Fund announces a different rate every year based on investment performance.
Rates have ranged from 0.10% during the 2008 subprime crisis to 6.50% in 2003, with a true average of 3.59%. Each rate applies to a different fund balance, so a flat average is fundamentally misleading.

4. Calculation Example — Numbers That Show the Picture
An employee contributing 10,000 THB per year (combined 3 sources) consistently for 28 years:
Total Gratuity with Compound Interest: ฿474,562
Interest Earned: ฿194,562 (+69.5% above principal)
Compound interest over 28 years increases your fund by nearly 70% — a figure that significantly affects whether lump sum or pension is the better choice for you.
5. Lump Sum vs Monthly Pension — Breakeven Age
Employees who have contributed for at least 180 months (15 years) can choose between two options:
Gratuity ฿474,562 ÷ Pension ฿5,475/month = 87 months
→ Breakeven Age = 62.2 years
Live past 62.2 → pension wins | Don't → lump sum wins

Example: Salary 15,000 THB, contributed 10 months → receive only 4,500 THB
Important: The government's 2.75% portion (per Cabinet resolution) is only received by lump-sum (บำเหน็จ) recipients — automatically determined by months contributed (under 180 months). Those who receive the monthly pension (บำนาญ, 180+ months) do not receive this government portion.
