Buying your first home is one of the most significant financial decisions you’ll make. A clear, realistic budget not only helps you secure the right mortgage but also ensures you can comfortably manage your new monthly payments and related expenses. In Canada, unique rules around down payments, mortgage insurance, stress tests, and government incentives shape how much you’ll need to save and spend.
1. Calculate Your True Take‑Home Income
Your budget’s foundation is your net (after‑tax) income. Knowing exactly how much you bring home each month ensures you set realistic spending limits.
- List all income sources. Include your regular salary deposit, bonuses, freelance earnings, or side‑gig Income.
- Use net amounts. Check recent pay stubs or bank statements for “net pay” rather than gross figures.
- Average variable Income. If you earn commissions, overtime, or tips, average the past three to six months. This smooths out highs and lows.
Pro Tip: Automate a monthly transfer of a fixed portion of your net pay into a dedicated savings account, so you “pay yourself first.”
2. Understand Canadian Down Payment Rules
The size of your down payment directly affects your mortgage amount, insurance requirements, and monthly payments.
- Homes up to $500,000. Minimum 5% down payment.
- Homes $500,000–$999,999. 5% on the first $500,000, plus 10% on the portion above $500,000.
- Homes $1 million or more. Minimum 20% down payment (no mortgage insurance allowed above 80% loan‑to‑value).
Example: For a $650,000 property, you need 5% of $500,000 ($25,000) plus 10% of $150,000 ($15,000) for a total of $40,000.
Saving for a larger down payment not only reduces your mortgage balance but may also lower your interest rate and eliminate the need for mortgage insurance.
3. Account for Mortgage Default Insurance
If your down payment is under 20%, you must purchase mortgage default insurance through CMHC, Sagen (formerly Genworth), or Canada Guaranty.
- Premium rates (added to mortgage):
- 5% down (95% LTV): 4.00% of mortgage
- 10% down (90% LTV): 3.10%
- 15% down (85% LTV): 2.80%
- 20% down (80% LTV): 2.40%
- Payment options:
- Add to the mortgage. Spreads the cost across your amortization, increasing monthly payments slightly, but keeps cash on hand.
- Pay upfront at closing. Avoids added interest but requires more cash at purchase.
Tip: Compare both approaches to determine which one best fits your cash flow.
4. Prepare for the Mortgage Stress Test
Since 2018, all insured mortgages in Canada have been required to undergo a stress test to verify that borrowers can afford payment increases.
- Qualifying rate: The greater of your contract rate + 2% or the Bank of Canada’s five‑year benchmark (5.25% as of July 2025).
- Impact on budgeting: Lenders calculate your maximum mortgage amount based on the higher, stress‑tested rate, even if your actual rate will be lower. This means you must show you can afford payments at the higher rate.
Budgeting note: Use an online stress‑test calculator to estimate your borrowing power under these conditions.
5. Estimate All Housing‑Related Costs
Your mortgage payment is just one piece of your monthly housing expenses. Include:
- Principal & Interest (P + I): Use a Canadian mortgage calculator or ask your lender for an amortization schedule.
- Property Taxes: Ontario rates range from 0.7% to 1.1% of the assessed value. Divide the annual tax by 12.
- Heat, Hydro, Water, and Gas: In Ontario, combined monthly bills typically range from $200 to $350.
- Home Insurance: Gather quotes from at least three insurers. Divide the annual premium by 12.
- Condo or Maintenance Fees: If you’re buying a condominium, include monthly strata fees.
- Routine Maintenance Fund: Allocate about 1% of your home’s value per year for repairs (e.g., $400,000 home → $4,000/year → $333/month).
Rule of Thumb: Aim to keep total housing costs under 32% of your gross monthly Income.
6. Track Your Current Monthly Expenses
To see exactly where your money goes today, review and categorize all spending:
- Fixed expenses. Car or student‑loan payments, phone, internet, insurance premiums, daycare or tuition.
- Variable expenses. Groceries, dining out, transportation, clothing, personal care, and entertainment.
- Periodic bills. Annual fees (vehicle registration, memberships), holiday gifts, and RRSP contributions—divide by 12 for monthly planning.
Action Step: Pull three months of bank and credit‑card statements and log expenses in a spreadsheet or budgeting app.
7. Identify and Implement Savings Strategies
If your budget is tight or you’d like more breathing room, consider:
- Cutting variable costs. Cook more meals at home, pause rarely used subscriptions, and compare grocery flyers for deals.
- Negotiating fixed costs. Shop around for car or home insurance; refinance high‑interest debt where possible.
- Delaying non‑essentials. Postpone big‑ticket purchases—new furniture or vacations—until you have a stable cushion.
- Increasing Income. Take on a freelance project, sell unused items, or request overtime if available.
Even small changes—like saving $50 a month on entertainment—compound over time.
8. Set and Automate Your Savings Goals
Building a habit of saving ensures you’re prepared for both planned and unexpected expenses:
- Emergency fund: Target three to six months of living expenses before closing on your home.
- Down payment top‑up: If you’re still building your down payment target, automate a weekly or monthly transfer.
- Home maintenance and renovation: Even $100 per month adds up to $1,200 a year for painting, repairs, or upgrades.
Tip: Use separate high‑interest savings accounts or Tax‑Free Savings Accounts (TFSAs) for each goal.
9. Monitor, Review, and Adjust
A budget is a living document. As your life and finances evolve, so should your budget:
- Monthly reviews. Compare actual spending to your plan. Note which categories need adjustment.
- Refine your targets. If you consistently overspend on groceries, update that line. If you beat your entertainment budget, consider redirecting excess to savings.
- Celebrate milestones. Paid off a credit card? Hit your emergency fund target? Acknowledge your progress to stay motivated.
Regular check‑ins prevent minor discrepancies from turning into larger financial stress.
10. Leverage First‑Time Home Buyer Programs
Canadian programs can reduce your upfront costs and free up monthly cash:
- Home Buyers’ Plan (HBP): Withdraw up to $35,000 from your RRSP tax‑free for your down payment. Repay over 15 years.
- First‑Time Home Buyer Incentive: A shared‑equity mortgage with CMHC that lowers your monthly P&I payment. You repay a percentage of your home’s value when you sell.
- Land Transfer Tax Rebate: First-time buyers may claim up to $4,000 off the provincial land transfer tax (additional municipal rebates may apply in some cities).
Note: Incorporate any repayment commitments (like the HBP) into your long‑term budget plan.
