Term plan insurer not stupid also. As you age you think they offer better deals? If you are the insurer will you do loss making business? Customer older higher chance to claim from you so why will you price your term life cheap? In fact for some insurers term plan end at age 65.
I did a quick and rough calculation
if you get a term life of 100k at 25yo at a premium of $110.10(fixed term from FWD as example)
total cost from 25yo-64yo would be 110.10*39=$4293.9
now compare that to DPS. For this one you have to put in more work because the prices are different for different age
but if you did the math you would pay $4947 for the same length of coverage
Other than its cheaper you also have to consider ….
1. for DPS coverage amount from 25-59yo is 70k for 60-64yo is 55K while the lowest fixed term is 100k
2. for fix term it is… well fixed. But for DPS, they might change premium amount in the future who knows?
3. fix term you can cover up to 70yo(e.g from FWD), DPS stops at 64yo
biggest pro of DPS? Can use CPF to pay
buy what? Your money, you decide
