It is possible that you are later in the savings schedule as compared to those who started their plan early. The effects of compounding, a benefit of investing early in an RESP, may help explain your question. Let's look at this example. If you invest $1,000 today at 2% per month, you will have $1020 ($1000 x 1.02) at the end of one month. If you keep this money invested, and you continue to earn 2% per month, your investment will grow to $1040.40 ($1020 x 1.02) by the end of the second month. The income you earned in the first month works with your original investment to earn income. So, you can see that the earlier you start contributing and the longer you keep your money invested, the more of an impact that compounding will have. This means that if your beneficiary is in the later stages of their plan and you increase your contribution, the effects of compounding and the returns on investment will not be as large as for someone who has just started their plan for a newborn.
