If you like to increase the amount you leave to your beneficiaries, you could consider this approach used by one of our older clients.
The annuity is guaranteed for 25 years and life which means that payments will continue to 2036 at least.
While our client does not expect to live until 115 years of age, the payout of approximately 6.5% per year will continue to a benficairy. Obviously shorter term guarantees and different annuity capital amounts will give different results.
This client has used her age to generate a better guaranteed and longer return for her neice. It also achieves perhaps helping to pay a mortgage.
