📖 Why Does This Calculator Exist?
Many workers who have been contributing to Thailand's Social Security Fund for years ask the same questions: "How much will I get if I leave the system now?" or "Is it worth continuing until I hit 180 months to qualify for a monthly pension?" The data needed to answer these questions is scattered across dozens of government gazette publications — nearly impossible for ordinary workers to access and compute themselves.
Your retirement gratuity isn't just what you personally contributed. It includes employer contributions and government contributions, plus investment returns that the SSO Fund announces each year via the Royal Gazette. Dr. Boon compiled all 26 years of this data into a single, easy-to-use calculator.
⚠️ How Is Your Retirement Money Calculated?
Contributions
Employee 3% + Employer 3% = 6% of salary base (max ฿15,000/month). The government makes an additional contribution only in certain years of economic crisis — such as the Global Financial Crisis and COVID-19 — not every year as a fixed amount.
Monthly contribution = Salary base × 6% (Employee 3% + Employer 3%)
+ Government top-up in select crisis years only (not every year)
+ Annual interest per Royal Gazette (1999–2026)
= Total retirement lump sum
💡 Example: Based on ฿10,000/month salary, 28 years of contributions (1999–2026) — the calculator produces a total of ฿474,562.49, split as ฿280,000 principal + ฿194,562.49 accumulated interest over 26 years.

🇲🇲 Why Is It Available in Burmese?
Thailand is home to a large population of Myanmar migrant workers who are enrolled in Thailand's Social Security system under Section 33. They contribute every month just like Thai workers, but many have no idea what rights they hold — or that there is money waiting for them in the fund.
Crucially, there is now a special law in the process of being enacted that will allow foreign migrant workers who have returned to their home country and will not be coming back to Thailand to claim their retirement gratuity (บำเหน็จชราภาพ) and take it home with them directly — without needing to meet the same conditions as before. This is a significant entitlement that the vast majority of Myanmar workers are completely unaware of.
This calculator was deliberately built to support the Burmese language so that Myanmar workers can check their own entitlements and estimate how much they are owed — without needing an interpreter. That money belongs to them, and they deserve to know it exists.
🏛️ How Migrant Workers Abroad Can Claim Their Money
Thai Embassy route: File through the Labor Department at the Thai Embassy in your country of residence — no need to travel back to Thailand.
Power of attorney: Authorize a family member or representative in Thailand to submit form SSO 2-01 on your behalf.
Time limit: Claims must be filed within 2 years of the date your insured status ended.
🌏
Everyone who contributes deserves to know what they'll receive
Whether you're a Thai worker, a Myanmar migrant, or from any other country — if you work in Thailand's formal employment system and pay into the Social Security Fund, you have a right to know where your money is and how much you'll get back. That's why this tool was built in three languages. Social security rights should be accessible to everyone.
"Your Social Security money is the result of years of hard work. Knowing exactly what you're owed isn't a privilege — it's your most basic right as a contributor."
— Boon Arayapon, Thailand Social Security Advocate
🔢 How to Use the Calculator — 3 Easy Steps
All the data you need is in the SSO Plus app (note: the correct app name is "SSO Plus," not "SSO Connect"). Open the app and navigate to Retirement → Annual Details to find your per-year contribution figures.
🎯 3-Step Guide to Your Retirement Estimate
Step 1 — Open SSO Plus: Download the free app from the App Store or Play Store. Log in with your Thai national ID (or passport/work permit for migrants). Go to Retirement → Annual Contribution Details.
Step 2 — Enter Your Data: Open the calculator at boonarayapon.com/calc-sso/ and enter your annual savings figures in the provided table. Or use the "Fill Average" button for a quick estimate.
Step 3 — Read Your Results: The system calculates your total payout with 26 years of compounded interest, compares lump sum vs monthly pension options, and automatically displays your "3-Kor Policy" entitlements.
⚖️ Lump Sum vs Monthly Pension — Which Is Better?
There's no single right answer — it depends on how many months you've contributed, your health, and your financial needs. The calculator shows both options side-by-side so you can make an informed decision.
Contributors with fewer than 180 months of contributions receive a one-time lump sum at age 55 or upon leaving the system. This includes employee and employer contributions plus accumulated interest. The government makes an additional contribution only in crisis years (e.g. Global Financial Crisis, COVID-19) — not as a fixed annual amount. Important caveat: Those with fewer than 12 months of contributions receive only their own share — no employer or government portion, and no interest calculation applies.
Those who contribute for 180+ months (15 years) qualify for a monthly pension for life. The rate is calculated from the average of the highest 60 months of salary (Best 60 Months / B60M Model). Base rate is 20%, increasing by 1.5% for each year beyond the first 15. Example: 28 years of contributions = 38.0% = approx. ฿3,800/month on a ฿10,000 salary base.
⚖️ Who Benefits Most from Each Option?
Lump Sum
Best for
Those with fewer than 180 months contributed, those who need capital for investment or debt repayment, and those with shorter life expectancy due to health conditions.
Monthly Pension
Best for
Those at or near 180 months, those who want steady retirement income, and those expecting a long life — pension becomes more valuable than lump sum after approximately 14 years (the "break-even point").
🏛️ Data Source — 26 Royal Gazette Announcements
The interest rates used in this calculator come from the official SSO retirement benefit return announcements published in Thailand's Royal Gazette — 26 separate documents covering 1999 through 2025. These are typically published around March 17th each year.
The highest recorded rate was 6.50% (1999), while the lowest was 0.10% (2020, during COVID-19). The 2025–2026 rates use the most recent projected figure of 2.81%. The calculator will be updated automatically when official rates are published.
❓ Key Questions Answered
Can Section 39 (self-employed) contributors use this calculator?
Yes. The calculator works for both Section 33 (employed) and Section 39 (voluntarily insured / formerly employed) contributors. Months under both sections can be combined — but if the total is still under 180 months, the payout remains a one-time lump sum rather than a monthly pension.
I'm a Myanmar migrant worker who has left Thailand. Can I still claim my money?
Yes — and there's a key channel many workers don't know about. You can file your claim through the Labor Department at the Thai Embassy in your home country, without needing to travel back to Thailand. Alternatively, you can submit form SSO 2-01 within 2 years of leaving the system, or authorize a representative in Thailand to file on your behalf. If you have returned home permanently, the Thai Embassy route is often the most practical option.
How accurate is the calculator?
The figures are estimates based on the data you enter. Your actual payout may differ slightly from the official SSO records. For the precise figure, submit form SSO 2-01 or contact your local SSO office directly. Use this tool for planning purposes — not as an official document.
What is the "3-Kor Policy" shown in the calculator results?
The "3-Kor" (3 ขอ) policy is a proposal championed by Dr. Boon and the "Not Begging, Reclaiming" movement: (1) Right to Choose — a fair pension formula, (2) Right to Reclaim — withdraw contributions if you leave the system early, and (3) Right to Borrow — use your retirement savings as loan collateral.

What is the SSO Plus app and where do I get it?
SSO Plus (ไม่ใช่ SSO Connect) is the official mobile app from Thailand's Social Security Office. Available free on iOS (App Store) and Android (Google Play). Log in with your 13-digit national ID or passport number. Navigate to Retirement → Annual Details to find the contribution data needed for this calculator.
🧮 Know Before You Decide
Your Social Security retirement fund represents years of contributions — yours, your employer's, and the government's. You have every right to know exactly how much has accumulated and which option suits your situation best. The calculator is free and available in three languages.
