If you are looking for capital guaranteed annuity which is also entitle for the tax relief of RM3000, Great Eastern do have it, I'll be honest enough to tell you the interest rate is roughly 3.5% based on my own calculation.

Because great eastern didn't promise sky high return, amere 3.5% for 20 years can get from a bbasic bond or even FD. unless someone told you about 5% then you should be surprise. This annuity plan do not have any cash bonus or survival benefit or anything non-guarenteed, means at the end of the day, you will be expecting nett nett 3.5% with no potential of extra and no potential of less. Like FD. But it is eligible for the tax relief.

Yes, u may use financial calculator or excel file to calculate the IRR.
