Canada RESP + CESG + Child Benefit (CCB) Calculator

This calculator combines two of Canada's major family-support programs into one tool, because most Canadian parents are managing both simultaneously: the Registered Education Savings Plan (RESP), a tax-deferred account for a child's post-secondary education that the federal government tops up with a matching grant (the Canada Education Savings Grant, CESG), and the Canada Child Benefit (CCB), a monthly, income-tested cash payment made directly to eligible families regardless of whether they save anything at all.

The RESP + CESG side works like this: any Canadian resident can contribute to an RESP for a beneficiary (no annual limit, though a C$50,000 lifetime cap per beneficiary applies), and the growth inside the account is tax-deferred until withdrawal. On top of your own contribution, the federal government adds a CESG grant equal to 20% of what you contribute, up to C$500 per year ordinarily, or up to C$1,000 per year if you're using carried-forward grant room from an earlier year where you contributed less than the full amount -- all capped at a C$7,200 lifetime maximum per child.

The CCB side is entirely separate and income-tested: it pays a maximum annual amount per child (higher for children under 6, lower for ages 6-17), which then gets reduced as your family's Adjusted Family Net Income (AFNI) rises, using a two-phase reduction formula that gets steeper as your number of children and income both increase.

RESP + CESG, over 15 years: C$2,500/year contribution, C$5,000 starting balance, 5% annual return.

Year 1's grant is C$500 (20% of C$2,500). Depositing C$3,000/year (contribution + grant) and compounding at 5%, after 15 years the account reaches C$74,830.33 -- C$37,500 in your own contributions, C$7,200 in cumulative CESG (the full lifetime cap is reached during year 15, since C$500/year x 14.4 years = C$7,200), and C$25,130.33 of tax-deferred investment growth.

CCB, 1 child under 6 + 1 child aged 6-17, AFNI C$75,000:

$$\text{Max Benefit} = \text{C\$8{,}157} + \text{C\$6{,}883} = \text{C\$15{,}040}$$

AFNI C$75,000 falls in the phase-1 band (2-children rate, 13.5%):

$$\text{Reduction} = (\text{C\$75{,}000} - \text{C\$38{,}237}) \times 13.5\% = \text{C\$36{,}763} \times 0.135 = \text{C\$4{,}963.01}$$

$$\text{Net Annual CCB} = \text{C\$15{,}040} - \text{C\$4{,}963.01} = \text{C\$10{,}076.99} \quad (\text{C\$839.75/month})$$

• The Canada Learning Bond (CLB). A separate, additional federal grant of up to C$2,000 lifetime for children from lower-income families, paid WITHOUT requiring any RESP contribution at all -- not modeled here, since it depends on family income and number of children in a way distinct from CESG.
• Provincial RESP grants. Some provinces (British Columbia's C$1,200 BCTESG, Quebec's refundable tax credit) add their OWN grant on top of the federal CESG -- not modeled here.
• RESP withdrawal rules (EAPs vs. contribution refunds). Withdrawing RESP funds involves splitting the withdrawal into an Educational Assistance Payment (taxable to the STUDENT, drawing from grant + growth) and a separate tax-free return of original contributions -- not modeled by this growth-only projection.
• The RESP's C$50,000 lifetime contribution limit per beneficiary. This calculator does not cap your MODELED contributions against that limit; check your own cumulative total separately.
• CCB's true income-splitting/shared-custody rules. Shared-custody parents each receive 50% of the CCB they'd otherwise qualify for individually -- not modeled here, which assumes a single household claiming the full amount.
• CCB base-year timing. The AFNI entered is treated as directly determining THIS benefit year's payment; in reality, the July 2026-June 2027 CCB uses your 2025 tax return's AFNI, with the following year's benefit based on the NEXT year's return.
• The Child Disability Benefit (CDB). An additional CCB top-up for a child eligible for the Disability Tax Credit -- not included in this calculation.

• Not contributing at least C$2,500/year and leaving CESG money on the table. Contributing less than C$2,500 in a year means missing part of that year's full C$500 CESG match -- though the unused GRANT ROOM (not the contribution room itself) carries forward, so it can be caught up on later at the C$1,000/year catch-up rate.
• Assuming CESG is unlimited. It is not -- C$7,200 is a hard LIFETIME cap per beneficiary, reached at C$36,000 of total lifetime contributions if you always get the full 20% match (C$36,000 x 20% = C$7,200). Contributions beyond that still grow tax-deferred, they just stop earning any further grant.
• Confusing the RESP contribution limit with the CESG grant cap. RESP contributions themselves have no ANNUAL cap (only a C$50,000 LIFETIME cap); it's specifically the CESG GRANT that has both an annual cap (C$500/C$1,000) and a lifetime cap (C$7,200).
• Forgetting the CCB reduction rate rises with more children. A family with 4+ children faces a materially steeper reduction curve (23% phase-1, 9.5% phase-2) than a single-child family (7% phase-1, 3.2% phase-2) -- more children raises the maximum benefit, but each additional dollar of income above the thresholds is clawed back faster too.
• Treating CCB and RESP/CESG as the same program. They are entirely independent: CCB is a monthly cash payment with no savings requirement at all, while CESG is strictly a MATCHING grant tied to money you actually deposit into an RESP.

• Income Tax Act (Canada), s. 146.1, "Registered Education Savings Plans," and the Canada Education Savings Act -- the CESG's 20% match, annual caps, and C$7,200 lifetime cap.
• Income Tax Act (Canada), s. 122.61, "Canada Child Benefit" -- the AFNI-based reduction formula.
• CESG figures (20% match, C$500/C$1,000 annual caps, C$7,200 lifetime cap): cross-verified across Questrade, Embark, RBC Royal Bank, and Wealthsimple.
• CCB figures for the July 2026-June 2027 benefit year (C$8,157/C$6,883 maximums; C$38,237/C$82,847 AFNI thresholds; phase-1 rates 7%/13.5%/19%/23%; phase-2 rates 3.2%/5.7%/8%/9.5%): cross-verified across multiple independent CCB calculator and news sources, with the phase-2 fixed dollar amounts independently arithmetic-checked against the phase-1 rates and thresholds for internal consistency. canada.ca's own CCB calculation-sheet pages returned an HTTP 403 to direct fetch in this session and could not be independently re-confirmed against the primary source in this pass -- cross-verify directly against canada.ca or CRA My Account before relying on this calculator for a real benefit estimate.
