How the planner calculates
- Each contribution scenario applies the same frequency and start date. There is no annual RESP contribution limit for 2007 and later years, but contributions are capped when the beneficiary’s entered lifetime contribution history plus planned deposits reaches $50,000. The model tracks future personal deposits, basic CESG, additional CESG, and CLB separately.
- Basic CESG is modeled at 20% of eligible contributions, up to $500 of grant in a year, or up to $1,000 when unused grant room is available for catch-up. The projection uses user-confirmed unused basic grant room, adds $500 of room in later eligible years, and observes the $7,200 lifetime CESG maximum. The 16–17 condition is checked separately.
- Additional CESG is modeled only with the income checkbox confirmed. It applies to at most the first $500 of contributions in each calendar year using the 2026 income band, and is included within the $7,200 lifetime CESG limit. Income and grant thresholds are held constant in future years.
- CLB is independent of personal contributions. Potential future CLB is added in July benefit periods when the entered income and eligibility assumptions pass. A new initial $500 CLB includes the separate one-time $25 account-opening payment. Prior payments are not added again because the current RESP balance already includes them. The model does not estimate CLB for prior eligible years or processing timing.
- Month-level convention: projection starts with the first whole calendar month after the balance date. Each modeled month begins with any scheduled contribution and estimated incentive, then compounds the resulting balance by the monthly equivalent of the effective annual return:
(1 + annual return)^(1/12) - 1. The balance-date month and education-start month are excluded. Government incentives are assumed credited in the contribution month, earlier than actual processing may occur.
RESP withdrawals: This tool stops at the projected account value. It does not assume the full balance is paid tax-free to the student: contribution refunds are generally tax-free, while educational assistance payments (grant, bond and earnings) are included in the student’s income when paid, subject to the rules. Other RESP payments can have different tax treatment. It does not model education withdrawals or account closure. See CRA: RESP payments and their tax treatment.
