hi guys,
first of sorry for the confusion. ING is indeed cheaper than Allianz if you look at a premium per 1k cover be it lifetime or just at a specific age (30). i have looked at the cummulative premium due for cover 1-70 and then calculated the average cost per 1k cover. why can i do this without knowing future medical inflation? first of i have todays premiums for various plans. so in todays terms i can give an absolute number to compare. this is good but but not perfect. but there is also another important thing to consider: i can assume that medical inflation will apply to all plans. so UNLESS the risk structure varies significantly between insurers (which it should if you look at such a large age band) then it can be assumed with a decent probability that the medical inflation will be by and large the same across insurers and as such premiums will rise in tandem. so the cheapest plan will likely remain the cheapest plan. mind you this will only apply to a 1k cover comparison and will be more true for high-end plans than low-end plans because the buffer (annual limit/lifetime limit) is larger and it attracts a better range of insured parties than a low-end plan. the uncertainty for low-end plans will be significantly higher. you can also see this if you look at the cost for low end plans. long term cover hovers around 15-20 RM per 1k cover whereas for the high end plans its about 5 RM. its simply more likely to have a higher percentage of claims in comparison to the limit (i.e. a 5k claim on 50k limit is 10% with 500k limit its just 1%).
anyway - it's a good rule of thumb to do a comparison. you could if you want to feed the entire historical premiums into an econometric forecast and start predicting the inflation rate for each plan and then derive a projected forcast. i dont know for sure but i think it would not be that much different for a look at a 70yrs cover.
i very much agree with the argument made regarding the switch. switches are only possible until you get really sick. then you will be stuck with whatever plan you hold at that point in time or face heavy loadings. but this also means that while you are in good health you should do a regular survey to ensure you have the best possible cover given your requirements and market offers.
and i am very much convinced that there is a personal best plan for everyone around given personal priorities / requirements and the plans in the market. it might not be the dream plan but it can be the best the market has to offer you. slight difference in perspective from what Vitorbarbosa is aiming at - yes i did understand what you mean

what i was pointing out with the top up idea is this:
you can get a wide cover for the major issues and add a plan with a high deductable that covers a specific subfield that you really want to have. this of course leads to a multitude of permutation options and as such would require a programm to find the cheapest cover.
for example you can combine axa 100k plan (7,65 per k for a male 1-70 avg) with a top up plan that comes with a deductable of 10 or 20k. the first part would be covered by axa in case of dialysis - 20k limit - the extra cost could be as little as 2,45 per k extra.
so your costs end up at 10,10 per k cover.
if you want a higher annual/lifetime limit i.e. you take the 500k plan from axa and top it up with 2,45 (tokio marine) you end up at a cost of 6,69 per k - albeit you get a very high cover - 500k + 150k booster (750k lifetime limit). and the premium you have to pay is of course higher than for a 100k plan. i hope i did make a bit of sense here

to do a number comparison: axa 100k + tokia marine medic partner 150k plan gives an average premium of 1134 RM for males (1-70). ING is 941,66. so its 200 bucks extra that give you: no lifetime limit, 750 lifetime 150k limit booster from TM and 50k p.a. dialysis, 150k cancer. to me this does make sense esp. since i am not stuck with the 300k limit from ING - which also applies to dialysis and cancer btw.
sorry for the long post. i hope it was not too confusing/complicated. not that easy to formulate the underlying considerations in a straight-forward manner all the time.
