The annuity rate is the equation used to convert an accumulated pension fund into a regular income in retirement.
The factor used in this equation will depend on the type of annuity that is being bought, for example whether it is single or joint life, level or increasing each year, as well as your age and health. Annuity rates vary between providers, so it is best to shop around for the best rate before buying an annuity. Annuity rates can also be affected by interest rates, inflation and the return on Government bonds.
