How we worked it out
Updated as you change the numbers.
- Each year: add the contribution (start or end of the year), grow the balance by the return, then raise the next contribution by the increase rate.
Method and assumptions
This models the accumulation phase of an annuity or any regular saving plan. With no increase, it matches the future value of an annuity. A rising contribution is a growing annuity, useful when contributions keep pace with pay rises. Fees inside commercial annuity products are not included.
