How Bangladesh government pension is usually worked
For superannuation, qualifying service of 25 years or more is treated as the full rate: 90% of last basic. From 10 to 24 years the rate is proportionate at 3.6% per year (so 10 years = 36%, 15 = 54%, 20 = 72%). Six extra months are commonly counted as another year. Below 10 years there is normally no ordinary pension except death, invalidation or abolition of post.
Monthly pension in the familiar clerk’s formula is (last basic × rate) ÷ 2, then add medical allowance (৳1,500, or ৳2,500 for many 65+ pensioners). The other half of gross pension is “sold” to the government. That surrendered half × 230 is the lump grant / আনুতোষিক now quoted in most offices (the factor has changed over the years — type a different factor if your order says so).
PRL lump grant is a separate line: last basic × remaining earned leave in months (often capped at 18). Family pension is shown here as half of the monthly figure as a rough guide only.
