How this is calculated
Formula used
Each period, your balance grows by the equivalent periodic rate derived from your expected annual return, and your monthly contribution is added. With monthly compounding, growth and contributions are applied every month; with annual compounding, contributions accumulate through the year and growth is applied once at year-end.
Example
Starting with MX$50,000 and adding MX$3,000 every month at an expected 8% annual return, monthly compounding, over 15 years projects to roughly MX$1.16 million, of which about MX$590,000 came from contributions and the rest from estimated growth.
