TFSA vs RRSP for compound interest: which is better?

Depends on tax bracket. RRSP wins if your retirement marginal rate is LOWER than today (deduction upfront + lower tax on withdrawal). TFSA wins if rate is the same or higher (no deduction but truly tax-free withdrawals). For middle earners (30% bracket): max TFSA C$7K/yr first, then RRSP. For high earners (45%+): max RRSP first for the deduction. Both compound completely tax-free internally.

How much TFSA contribution room do I have?

2026 annual TFSA contribution room: C$7,000. If you were 18+ in 2009 (when TFSA launched) and never contributed, your cumulative room is C$95,000 (sum of all annual limits 2009-2026). Withdrawals from TFSA restore contribution room the next calendar year. Check exact room via your CRA My Account.

What return rate for Canadian stocks (TSX)?

The S&P/TSX Composite has returned about 8% nominal annually over the past 30 years (including dividends) — roughly 6% real after inflation. Lower than US S&P 500 (10% nominal) due to heavy resource/financial sector weighting. For projections: 7% nominal for diversified Canadian portfolio (XIC, VCN), 9% nominal for US/global tilt (VFV, XAW).

How does RESP compound interest work with government grants?

RESP receives a 20% Canada Education Savings Grant (CESG) match up to C$500/yr (on C$2,500 contributed), maximum C$7,200 lifetime. Plus growth is tax-deferred and withdrawals are taxed in the child's hands (typically zero tax). Example: C$2,500/yr × 18 yrs = C$45,000 contributed + C$7,200 CESG = C$52,200 invested. At 7% real return, that grows to ~C$108,000 by university age. Best risk-free 20% return in Canadian investing.

Compound interest formula for Canadian investments?

Standard formula: A = P × (1 + r/n)^(n×t). Monthly compounding: A = P × (1 + r/12)^(12×t). With monthly contributions: FV = PMT × [(1 + r/12)^(12×t) − 1] / (r/12). Use 6-7% real for equity-heavy registered accounts, 4-5% nominal for HISAs, 3-4% for GICs.

What is the RRSP contribution limit for 2026?

2026 RRSP contribution limit: 18% of prior year earned income, up to a maximum of C$32,490 (subject to CRA confirmation). Unused contribution room carries forward indefinitely. Check exact room on your CRA Notice of Assessment.

Quick answer · 4 Canadian scenarios

C$500/mo TFSA at 7% for 30 yrs

= C$610,000 · C$180K contributed · C$430K compounding · tax-free

C$7K/yr full TFSA at 7% for 25 yrs

= C$443,000 · all tax-free at withdrawal

C$2,500/yr RESP + C$500 CESG at 7% for 18 yrs

= ~C$108,000 by university age · government adds 20% match

C$10K GIC at 4.5% for 5 yrs (annual compounding)

= C$12,461 · principal compounding · taxable outside TFSA

Key Canadian terms

TFSA: Tax-Free Savings Account. C$7K/yr (2026) contribution room. Growth + withdrawals fully tax-free. Withdrawals restore room next year.
RRSP: Registered Retirement Savings Plan. 18% of income, max C$32,490 (2026). Tax deduction now, tax on withdrawal. Tax-deferred growth.
RESP + CESG: Education savings. 20% government match up to C$500/yr (C$7,200 lifetime). Tax-deferred growth, taxed in child's hands.
XIC / VCN / VFV: Top Canadian ETFs: XIC (TSX, 0.06% MER), VCN (FTSE Canada, 0.05%), VFV (S&P 500, 0.09%).

TFSA: the workhorse

The TFSA is Canada's most powerful compounding tool for most savers. C$7,000/year (2026 room) goes in after-tax but grows AND comes out completely tax-free at any age. No income limits, no penalty for withdrawals. Cumulative room since 2009 = C$95,000 for someone 18+ that year. Math:

C$500/month TFSA at 7% real return for 10 years → C$86,400
C$500/month TFSA at 7% real return for 20 years → C$260,000
C$500/month TFSA at 7% real return for 30 years → C$610,000
C$500/month TFSA at 7% real return for 40 years → C$1.31M

RRSP: tax-deferred power

RRSP contributions reduce your taxable income today (tax refund) and grow tax-deferred. You pay tax only on withdrawal. Optimal use: contribute when in a HIGH bracket (45%+), withdraw when in a LOW bracket (retirement). A C$10,000 contribution at 45% marginal saves C$4,500 in tax — that refund can fund TFSA contributions, doubling your effective savings.

RESP: the 20% guaranteed return

The Canada Education Savings Grant (CESG) matches 20% of RESP contributions up to C$500/year (on C$2,500 contributed). Lifetime maximum C$7,200 per child. This is a 20% instant return BEFORE any compound growth — the best risk-free return in Canadian personal finance. Family with one child should max C$2,500/yr from birth to age 14 to capture the full grant.

Canadian ETFs: XIC, VCN, VFV, XAW

Cheapest broad-market exposure for Canadians: XIC (S&P/TSX Composite, 0.06% MER), VCN (FTSE Canada All Cap, 0.05% MER), VFV (S&P 500, 0.09% MER), XAW (FTSE Global All Cap ex-Canada, 0.20% MER). A typical diversified Canadian portfolio: 30% VCN + 50% VFV + 20% XAW + bonds via VAB or ZAG.

HISA vs GIC

Canadian HISAs (EQ Bank, Wealthsimple Cash, Tangerine) pay 3-5% with daily compounding, fully liquid. GICs (Guaranteed Investment Certificates) lock funds 1-5 years for 4-5% rates. Both fully taxed outside TFSA. Inside TFSA: zero tax, ideal for emergency fund + short-term goals.

Inflation and real returns in Canada

Canadian CPI averaged ~2% long-term, spiked to 8% in 2022. Use real returns (after inflation): 6-7% real for diversified global equity, 1-2% real for HISAs, 2-3% real for GICs. Our calculator shows nominal and inflation-adjusted side-by-side.

Why this calculator and not the others?

Snowballr publishes six compound-interest variants because the math is the same but the conventions, defaults, and product context differ. Here's where this one fits and when to switch to another.

You're using:

Canada compound interest calculator (CAD)

Best for: CAD-denominated savings: TFSA, RRSP, RESP, high interest savings, Canadian ETFs (XIC, VCN, VFV). Defaults reflect Bank of Canada policy rate (2026) and CAD formatting.

A = P(1 + r/12)^(12t) — same math, CAD labels + TFSA/RRSP-aware copy

Switch away if: USD or other currencies — use General with currency override. RRIF withdrawals need the Retirement calculator.

Backed by our research: 10,000 deterministic Monte Carlo scenarios — methodology, percentile distribution, and the year interest beats contributions.

Other Snowballr compound calculators
