example
Expenditure 30,000 baht/month Retirement 60 Year Age 85 Year (300 Month) Return 4% Inflation 3% Real monthly return ≈ 0.0806% Target money ≈ 5.7 million baht (in today's value)
Frequently asked questions
How much do you need to retire?
Depending on the monthly post-retirement expenses and the required period, for example, if you spend 30,000 baht/month, retire at 60 years, 85 years (25 years after retirement) and earn 4% per year, you will need to spend about 5.7-6 millionbaht. This calculator automatically calculates both inflation and earnings.
How does inflation affect retirement planning?
Inflation increases real expenditure every year. If inflation is 3% per year, the expenditure 30,000 baht today will be 60,000 baht in another 24 year. Good planning takes inflation into account by using real return, which is the return minus inflation.
What is the life expectancy in Thailand?
The average life expectancy of Thai people is currently around 77-79 years, but for safety in retirement planning, it is recommended to use life expectancy of 85-90 years to prevent the risk of overliving.
How much should the post-retirement benefit be set?
