RESP Calculator Canada
Calculate how your Registered Education Savings Plan grows with monthly contributions, compound investment returns, and the Canada Education Savings Grant (CESG). See the total you can save for your child's post-secondary education by age 18, including government grants worth up to $7,200.
How the RESP Calculator Works
The RESP (Registered Education Savings Plan) is Canada's tax-sheltered education savings vehicle with a unique advantage: the federal government matches your contributions through the Canada Education Savings Grant (CESG). This calculator projects your RESP balance at age 18 by compounding your monthly contributions plus CESG grants at your expected return rate. All calculations run entirely in your browser with no data sent to any server.
Enter your monthly contribution amount, your child's current age, your expected annual return rate, and your family income bracket. The calculator determines your basic CESG rate (20% on the first $2,500 per year), checks whether you qualify for the Additional CESG (an extra 10-20% on the first $500 for lower-income families), and compounds everything year by year until the child turns 18. It also tracks the lifetime CESG cap of $7,200 and the $50,000 lifetime contribution limit per beneficiary.
RESP Growth Formula
Annual Contribution = Monthly Contribution × 12
Basic CESG = min(Annual Contribution, $2,500) × 20%
Additional CESG = min(Annual Contribution, $500) × Additional Rate
Year-End Balance = (Previous Balance + Annual Contribution + CESG) × (1 + Return Rate)
Where:
- Basic CESG = 20% match on first $2,500 contributed per year (max $500/year)
- Additional CESG = Extra 10-20% on first $500 for families earning under $106,717
- Lifetime CESG cap = $7,200 per child
- Lifetime contribution limit = $50,000 per beneficiary
Understanding the CESG and Additional CESG
The Canada Education Savings Grant is automatic free money from the federal government. For every dollar you contribute to an RESP, the government adds 20 cents on the first $2,500 per year, up to $500 per year in basic CESG. Over 18 years, this alone provides up to $7,200 in grants that compound alongside your contributions. To maximize the basic CESG, you need to contribute at least $2,500 per year, which works out to approximately $208.33 per month. Contributing more than $2,500 per year still grows tax-sheltered, but does not attract additional CESG matching beyond that threshold.
Lower-income families may also qualify for the Additional CESG, which provides an extra 10% or 20% match on the first $500 contributed each year. Families with adjusted income under $53,359 (2024 threshold) receive the full 20% additional rate, while families earning between $53,359 and $106,717 receive 10%. Families above $106,717 receive only the basic 20% CESG. The Additional CESG is included in the $7,200 lifetime cap. Separately, the Canada Learning Bond (CLB) provides $500 initially plus $100 per year (up to $2,000 total) for children in families receiving the National Child Benefit Supplement, requiring no personal contributions at all.
RESP Contribution Strategy for Maximum Growth
The optimal RESP strategy depends on your budget and timeline. Contributing $2,500 per year ($208.33/month) captures the full basic CESG, which is the most efficient use of each dollar contributed. If you start at birth and contribute $2,500 annually at a 6% return, the RESP reaches approximately $96,000 by age 18, including about $7,200 in CESG. If you can afford more, contributions up to the $50,000 lifetime cap grow tax-sheltered. Lump-sum catch-up contributions are possible, but the CESG only applies to the first $2,500 each year, plus up to $2,500 of unused prior-year CESG room (maximum $1,000 CESG in a catch-up year).

What Happens When Your Child Goes to School?
When the RESP beneficiary enrolls in a qualifying post-secondary program (university, college, trade school, or apprenticeship), Education Assistance Payments (EAPs) can be withdrawn. EAPs consist of the grants and investment growth, and are taxable in the student's hands, who typically has little or no income, making the effective tax rate near zero. Your original contributions come out tax-free since they were made with after-tax dollars. If the child does not pursue post-secondary education, you can transfer the plan to a sibling, transfer up to $50,000 of investment growth to your RRSP (if you have room), or collapse the plan with taxes and a 20% penalty on the growth. CESG and CLB amounts must be returned to the government if not used for education. The RESP must be used within 35 years of opening.
