Sarah walked into BMO's Vancouver branch to finalize her $375,000 mortgage. The loan officer presented two options: "You can take 5.49% with no upfront costs, or pay $3,750 now that's 1 point and we'll lower your rate to 5.19%." Sarah asked the question that puzzles thousands of Canadian homebuyers: "How does paying money upfront actually change my interest rate?"
The answer lies in understanding how mortgage points lower your interest rate through a mechanism called prepaid interest. When you pay points, you're essentially compensating the lender upfront for the interest revenue they'll lose by giving you a lower rate. It's not magic it's math. Lenders calculate the present value of future interest payments and offer you a trade: cash now in exchange for less interest monthly.
This guide reveals the complete mechanics behind mortgage point pricing. You'll learn exactly how lenders determine that 1 point equals a specific rate reduction, why the ratio varies between TD Bank and Scotiabank, and the step-by-step process that happens when you buy down your rate. We'll explore real 2026 pricing from Canadian lenders, show you the present value calculations behind the scenes, and explain why some borrowers get better rate-to-point ratios than others.
The Fundamental Mechanics of Mortgage Points
At its core, how mortgage points lower your interest rate comes down to a simple principle: you're prepaying interest. Lenders make money from the interest you pay over time. When you buy points, you give them some of that money upfront, so they can afford to charge you less interest monthly.
Understanding Prepaid Interest
Think of your mortgage from the lender's perspective. On a $300,000 mortgage at 5.29% over a 5-year term, RBC expects to collect approximately $76,200 in interest payments. That's their revenue. Now, if you pay $3,000 upfront (1 point) and they drop your rate to 5.04%, they'll only collect about $73,800 in interest over those 5 years about $2,400 less.
The Lender's Math:
- Scenario A (No Points): $0 upfront + $76,200 interest = $76,200 total
- Scenario B (1 Point): $3,000 upfront + $73,800 interest = $76,800 total
- Result: Lender gets roughly the same total revenue, just structured differently
The lender actually makes slightly more with points because they receive cash immediately (which has more value than future payments). This time-value-of-money principle is why lenders offer points at all it benefits both parties when structured correctly.
Why 1 Point Typically Equals 0.25% Rate Reduction
The industry standard of 1 point = 0.25% rate reduction isn't arbitrary it comes from present value calculations. Lenders use complex formulas that consider:
- The loan amount and term length
- Expected prepayment rates (how many borrowers refinance early)
- Their cost of funds (what the bank pays to borrow money)
- Default risk and administrative costs
- Current market conditions and competition
When all these factors align in typical 2026 market conditions with 5-year Canadian mortgage terms, the math works out to roughly 0.25% per point. But this ratio isn't fixed it fluctuates based on market conditions and your specific situation.
How Lenders Price Mortgage Points
Understanding mortgage point pricing reveals why you might get different rate-to-point ratios from TD Bank versus a credit union. Lenders don't use a universal formula they adjust pricing based on dozens of variables.
Market Conditions Affect Pricing
When the Bank of Canada sets higher policy rates, the value of buying down your rate increases. In a 6% rate environment, getting a 0.25% reduction saves you significantly more per month than in a 3% environment. Lenders adjust their point pricing accordingly.
2026 Market Example:
Current Scenario (Rates ~5.5%): 1 point typically buys 0.25% reduction
If rates rise to 7%: Same 1 point might only buy 0.20% reduction (points less valuable)
If rates drop to 3%: 1 point might buy 0.30% reduction (points more valuable)
Why? Higher rates mean more interest revenue at stake. Lenders charge more for rate buydowns when the base rate is high.
Factors Affecting Your Personal Point Pricing
Not everyone gets the same deal. Your rate reduction per point depends on five key factors:
1. Credit Score
750+: Get best ratios (often 0.26%-0.28% per point)
680-749: Standard ratios (0.23%-0.25% per point)
Below 680: Reduced ratios or points not offered
2. Loan-to-Value Ratio (LTV)
Under 65% LTV: Premium pricing on points
65-80% LTV: Standard pricing
80-95% LTV: Limited point options, less favorable ratios
3. Loan Amount
Larger mortgages ($500,000+) often get better rate-to-point ratios. A $750,000 mortgage might get 0.27% per point while a $200,000 mortgage gets 0.23%.
4. Property Type
Primary residence: Best rates
Second home: 0.05% less reduction per point
Investment property: 0.10% less reduction per point
5. Lender Type & Competition
Big banks (TD, RBC, Scotiabank) have standardized pricing. Credit unions and brokers often negotiate better ratios to win business.
Real 2026 Pricing from Canadian Lenders
Here's what actual mortgage point pricing looks like at major Canadian lenders in mid-2026:
| Lender | Standard Ratio | Premium Clients | Notes |
|---|---|---|---|
| TD Bank | 0.25% per point | 0.26% (800+ credit) | Requires $400k+ loan |
| RBC | 0.24% per point | 0.27% (existing clients) | Relationship discounts |
| Scotiabank | 0.22% per point | 0.28% (negotiable) | Wide range, shop hard |
| BMO | 0.25% per point | 0.26% (low LTV) | Consistent pricing |
| Credit Unions | 0.23-0.27% | 0.28-0.30% | Most flexible |
Notice the significant variance: a borrower with excellent credit getting 0.30% per point from a credit union saves 20% more than someone getting the standard 0.25% from a major bank. This difference compounds over years making lender shopping crucial.
The Step-by-Step Process of Lowering Your Rate
Understanding the mechanics is one thing knowing exactly what happens when you buy down your interest rate is another. Here's the complete process from quote to closing.
Step 1: Rate Sheet Analysis
Every morning, lenders publish rate sheets showing their available rates and point pricing. Your mortgage broker or loan officer accesses these to determine your options.
Example Rate Sheet (TD Bank, 5-year fixed):
Base Rate: 5.39%
+0.5 points: 5.27% (-0.12%)
+1.0 points: 5.14% (-0.25%)
+1.5 points: 4.99% (-0.40%)
+2.0 points: 4.89% (-0.50%)
Step 2: Rate Lock with Points
Once you choose a rate and point combination, you lock it in typically for 90-120 days. This protects you if rates rise while your purchase completes.
Important: If rates drop before closing, some lenders let you "relock" at the lower rate. Others hold you to the original lock. Ask about float-down options when locking.
Step 3: Closing Disclosure
Points appear as "Discount Points" in Section A of your closing disclosure. This is a cash payment you cannot finance points into your mortgage amount.
Toronto Example ($520,000 home, $416,000 mortgage):
Down Payment: $104,000
Closing Costs: $8,200
+ Discount Points (1.5): $6,240
Total Cash Needed: $118,440
Step 4: Permanent Rate Documentation
Your mortgage documents permanently reflect the reduced rate (e.g., 4.99% instead of 5.39%). There's no expiration the rate stays lower for the entire mortgage term. At renewal after 5 years, you'll negotiate a new rate based on market conditions then, but the points you paid continue to save you money until that renewal.
Common Mistakes to Avoid
- ⌠Confusing "points" with "percentage points": 1 point = 1% of loan amount, NOT 1% interest rate drop
- ⌠Not getting written confirmation: Always get point pricing in writing before locking
- ⌠Assuming all lenders price equally: Shop 4-5 lenders ratios vary significantly
- ⌠Buying points on adjustable/variable rates: Points only work on fixed rates
- ⌠Depleting emergency funds to buy points: Never compromise financial security for rate buydown
How Much Rates Drop Per Point
The rate reduction per point follows a general pattern, though it's not perfectly linear. Here's what you can typically expect when buying points in Canada's 2026 mortgage market.
| Points Paid | Cost ($350k) | Starting Rate | New Rate | Rate Drop | Monthly Savings |
|---|---|---|---|---|---|
| 0 points | $0 | 5.39% | 5.39% | 0% | $0 |
| 0.5 points | $1,750 | 5.39% | 5.27% | 0.12% | $24 |
| 1 point | $3,500 | 5.39% | 5.14% | 0.25% | $51 |
| 1.5 points | $5,250 | 5.39% | 4.99% | 0.40% | $82 |
| 2 points | $7,000 | 5.39% | 4.89% | 0.50% | $102 |
Calgary mortgage example above: $350,000 loan at 25-year amortization. Notice that each additional 0.5 points doesn't provide exactly the same rate drop there's slight diminishing returns after 1.5-2 points.
Why It's Not Perfectly Linear
You might expect that if 1 point = 0.25% reduction, then 2 points would equal exactly 0.50%. Sometimes it does, but often you'll get 0.45%-0.48% instead. Three reasons why:
- Lender risk floors: Banks won't go below certain rates regardless of points paid
- Diminishing value: The lower the rate already is, the less additional reduction is worth to you
- Market rate constraints: Lenders can't offer rates too far below their cost of funds
Ottawa Rental Property Example:
Marcus owns a rental condo and wants to buy points on his $285,000 refinance. Because it's an investment property, Scotiabank offers reduced rate-to-point ratios:
- Primary residence pricing: 1 point = 0.25% reduction
- Investment property pricing: 1 point = 0.20% reduction
- Why the difference: Higher default risk on rental properties means lenders offer less favorable terms
Optimization Strategies for Maximum Value
Now that you understand the mechanics, here's how to extract maximum value when buying down your interest rate.
Strategy 1: Compare Effective Cost Per Basis Point
Don't just look at headline numbers. Calculate the cost per basis point (1/100th of 1%) to compare lenders apples-to-apples.
Vancouver Example ($450,000 mortgage):
Lender A: 1 point ($4,500) = 0.25% reduction → $180 per basis point
Lender B: 1 point ($4,500) = 0.28% reduction → $161 per basis point
Lender B is 11% more efficient choose them!
Strategy 2: Negotiate at Application, Not Pre-Approval
Point pricing becomes much more negotiable once you have a firm offer on a home. Lenders want to close deals, not lose them to competitors. Get pre-approved first, then shop aggressively when you're ready to lock your rate.
Strategy 3: Buy Fractional Points
You don't have to buy full points. Half-points (0.5) or even quarter-points (0.25) give you finer control over your trade-off between upfront costs and monthly savings.
Montreal Break-Even Scenario:
Elena wants to buy points but only plans to stay 4 years. Her analysis:
- 1 full point: 6.8-year break-even (too long)
- 0.5 points: 3.2-year break-even (perfect!)
By buying fractional points, Elena saves $1,920 over 4 years instead of losing money by overbuying.
When NOT to Buy Points
Sometimes buying points is the wrong move, even if the math works:
- Your emergency fund falls below 6 months of expenses
- You're considering a variable rate mortgage (points only work on fixed)
- You expect to refinance within 3 years
- Your break-even exceeds 60% of your planned ownership period
- You can get a better return investing the cash elsewhere (RRSP match, TFSA, etc.)
Frequently Asked Questions
Do mortgage points lower my interest rate permanently?
Yes, for the duration of that mortgage term. If you buy points on a 5-year fixed mortgage at 4.89%, that rate stays locked for all 5 years. When you renew at year 5, you'll negotiate a new rate based on current market conditions the points you paid don't carry over to the renewal.
Can I negotiate better rate-to-point ratios?
Absolutely. Lenders have flexibility, especially for strong borrowers or large mortgages. If you have 800+ credit, 40%+ down payment, or a $600,000+ mortgage, ask for enhanced pricing. Credit unions are particularly negotiable some will offer 0.28%-0.30% per point to win premium clients.
Are mortgage points tax deductible in Canada?
For primary residences, no. However, if you're buying an investment property, mortgage points may be deductible as a financing expense. Consult a tax professional for your specific situation CRA rules on rental property deductions can be complex.
What happens to my points if I refinance early?
You lose the remaining value. If you paid $4,000 for points expecting an 8-year break-even but refinance after 3 years, you've lost money. This is why break-even analysis is critical always pad your timeline expectations by 25-30% to account for life's uncertainties.
Do all Canadian lenders offer mortgage points?
Most major banks (TD, RBC, BMO, Scotiabank, CIBC) and credit unions offer points, but not all. Some online lenders and alternative lenders don't participate. Always ask specifically: "What rate-to-point ratios do you offer?" Don't assume it's available just because you're getting a mortgage quote.
Is there a limit to how many points I can buy?
Most lenders cap points at 2-3 maximum. Beyond that, the rate reductions become minimal due to lender risk floors. Practically speaking, buying more than 2 points rarely makes financial sense you're better off making a larger down payment or keeping the cash for investments if you have that much available.
Conclusion: The Math Behind the Lower Rate
How mortgage points lower your interest rate isn't mysterious it's a straightforward exchange of present value for future savings. When you understand that 1 point = 1% of your loan amount prepaying future interest, the mechanics become clear. Lenders calculate the present value of the interest revenue they'll lose by dropping your rate, and they charge you roughly that amount upfront.
The key insights for Canadian homebuyers:
- Standard pricing is 0.25% rate reduction per point, but ranges from 0.20%-0.30% depending on your profile
- Your credit score, LTV ratio, loan amount, and lender type all influence your rate-to-point ratio
- The process involves rate sheets, rate locks, closing disclosures, and permanent rate documentation
- Rate reductions aren't perfectly linear expect diminishing returns after 1.5-2 points
- Optimization strategies like comparing cost-per-basis-point and buying fractional points maximize value
Whether buying points makes sense for you depends on your break-even period, timeline certainty, and alternative uses for your cash. Understanding the mechanics empowers you to evaluate offers intelligently and negotiate confidently. When Sarah walked out of BMO with her mortgage documents showing 5.19% instead of 5.49%, she wasn't just saving $84 monthly she understood exactly why that rate reduction cost $3,750 and how the lender's math worked.
That's the power of understanding how mortgage points lower your interest rate.
