In the United States, “buying points” to lower your mortgage rate is standard practice. In Canada, the process is less formalized but still possible — and it can save you thousands if you do the math. Here is how rate buydowns work in Canada, when they make financial sense, and when you are better off putting that money elsewhere.
What is a mortgage rate buydown?
A rate buydown is when you pay an upfront fee to your lender in exchange for a lower interest rate on your mortgage. You are essentially prepaying interest — giving the lender money now in exchange for paying less interest over the term.
How it works
- You agree to a mortgage at, say, 5.00%
- You ask the lender if you can buy a lower rate
- The lender offers 4.75% if you pay 1% of the mortgage upfront ($5,000 on a $500,000 mortgage)
- Your monthly payment drops and you save on interest for the life of the term
Terminology
| Term | Meaning |
|---|---|
| Discount point | 1% of the mortgage amount, typically buys a 0.25% rate reduction (US term) |
| Rate buydown | General term for paying upfront to get a lower rate |
| Prepaid interest | The upfront payment — you are paying interest in advance |
| Break-even | The point where monthly savings exceed the upfront cost |
Rate buydown costs in Canada
Canadian lenders do not publish standardized “point” pricing like US lenders, but typical costs are:
| Rate Reduction | Approximate Upfront Cost | On $500,000 Mortgage |
|---|---|---|
| 0.10% | 0.40–0.60% of mortgage | $2,000–$3,000 |
| 0.15% | 0.60–0.90% | $3,000–$4,500 |
| 0.20% | 0.80–1.20% | $4,000–$6,000 |
| 0.25% | 1.00–1.50% | $5,000–$7,500 |
| 0.50% | 2.00–3.00% | $10,000–$15,000 |
Costs vary by lender, term length, and whether you are working through a broker. Shorter terms generally cost less to buy down because the lender’s risk exposure is shorter.
Break-even analysis
The fundamental question: how long until your monthly savings pay back the upfront cost?
Example: $500,000 mortgage, 25-year amortization, 5-year fixed term
| Detail | Standard Rate | Bought-Down Rate |
|---|---|---|
| Interest rate | 5.00% | 4.75% |
| Monthly payment | $2,908 | $2,833 |
| Monthly savings | — | $75 |
| Upfront cost | $0 | $5,000 |
| Break-even | — | 67 months (5.6 years) |
| 5-year savings | — | $75 × 60 = $4,500 − $5,000 = −$500 |
In this scenario, the buydown does not pay off within a 5-year term. You would need to keep the same rate for 5.6 years to break even.
Larger buydown example: $500,000 mortgage, 0.50% reduction
| Detail | Standard Rate | Bought-Down Rate |
|---|---|---|
| Interest rate | 5.00% | 4.50% |
| Monthly payment | $2,908 | $2,758 |
| Monthly savings | — | $150 |
| Upfront cost | $0 | $12,000 |
| Break-even | — | 80 months (6.7 years) |
| 5-year savings | — | $150 × 60 = $9,000 − $12,000 = −$3,000 |
Again, the break-even exceeds a 5-year term. This is the core challenge with rate buydowns in Canada — most terms are 5 years, but most buydowns need 5–7 years to pay off.
When rate buydowns make sense in Canada
Scenarios where buying down works
| Scenario | Why It Works |
|---|---|
| Longer mortgage term (7 or 10 years) | More time to recoup the upfront cost; break-even is typically reached within the term |
| Planning to stay in the home 10+ years | Even with a 5-year term, if you renew at market rates, the savings in the first term partially offset the cost |
| Very large mortgage ($750K+) | Monthly savings are proportionally larger, improving the break-even timeline |
| Lender offers an unusually cheap buydown | If 0.25% costs only 0.5% of the mortgage instead of 1%, the math improves dramatically |
| Cash-rich but income-constrained | Large savings but income limits your qualification — buydown lowers the payment used for GDS/TDS |
Scenarios where buying down does NOT work
| Scenario | Why It Fails |
|---|---|
| 5-year fixed term | Break-even typically exceeds 5 years |
| May sell or refinance within 5 years | You lose the upfront cost if you exit early |
| Small mortgage ($200K–$300K) | Monthly savings are small; long break-even |
| Variable rate mortgage | Rate changes make the buydown value unpredictable |
| Better use for the money | Putting $5,000 toward a larger down payment may save more |
Rate buydown vs alternative uses of the money
If you have $5,000–$10,000 available, how does a rate buydown compare to other uses?
$5,000 comparison on a $500,000 mortgage at 5%, 25-year amortization
| Use of $5,000 | Monthly Savings | Total Savings Over 25 Years | Note |
|---|---|---|---|
| Rate buydown (−0.25%) | ~$75/month | ~$22,500 over 25 years (if rate maintained) | Requires same rate at each renewal |
| Larger down payment | ~$29/month | ~$14,600 over 25 years | Guaranteed; reduces principal |
| Lump-sum prepayment in Year 1 | $0 (same payment) | ~$16,800 in interest saved | Shortens amortization by ~6 months |
| Invested in TFSA at 7% | N/A | ~$27,100 after 25 years | Market risk; not guaranteed |
Key insight
The rate buydown produces the highest monthly savings but only if you maintain the lower rate at each renewal. If rates change at renewal (which they almost certainly will after 5 years), the buydown benefit is limited to the initial term.
The lump-sum prepayment or extra down payment provides guaranteed savings regardless of future rate changes.
How to negotiate a rate buydown in Canada
Through a mortgage broker
Mortgage brokers have the most flexibility for rate buydowns because they work with multiple lenders.
- Ask your broker: “Is there a lender that offers a lower rate in exchange for an upfront fee?”
- Compare offers: Get the standard rate and the bought-down rate from multiple lenders
- Calculate break-even: Use the formula below for every offer
- Consider term length: A 7- or 10-year term improves the math significantly
Directly with your bank
Big 5 banks are less likely to offer explicit rate buydowns, but they may:
- Offer a relationship discount if you move other accounts (chequing, savings, investments) to them
- Reduce the rate if you accept a “collateral charge” mortgage instead of a standard charge
- Provide a lower rate for larger down payments (above 20%, 25%, or 35%)
- Offer cash-back mortgages (the reverse — they pay you upfront in exchange for a higher rate)
What to ask
| Question | Why It Matters |
|---|---|
| “Can I get a lower rate if I pay an upfront fee?” | Direct request for a rate buydown |
| “What rate would I get with a 25% down payment vs 20%?” | Tests if larger down payment buys a better rate |
| “Is there a rate advantage for a 7-year term?” | Longer terms may come with natural rate reductions |
| “What’s your best rate if I move my banking here?” | Relationship pricing is an indirect buydown |
Break-even formula
To calculate the break-even point for any rate buydown:
Break-even (months) = Upfront cost ÷ Monthly savings
Example
- Upfront cost: $6,000
- Monthly payment at 5.00%: $2,908
- Monthly payment at 4.75%: $2,833
- Monthly savings: $75
- Break-even: $6,000 ÷ $75 = 80 months (6.7 years)
If your term is 5 years (60 months), you will NOT break even. If your term is 7 years (84 months), you will break even at month 80 and save for the remaining 4 months.
Adjusted break-even (accounting for time value of money)
The simple formula above ignores the fact that the upfront $6,000 could have been invested. A more accurate break-even accounts for opportunity cost:
Adjusted break-even: upfront cost × (1 + monthly investment return)^n = cumulative monthly savings
At a 5% annual investment return, the $6,000 could earn ~$25/month. So the effective monthly savings is $75 − $25 = $50, and the adjusted break-even is:
$6,000 ÷ $50 = 120 months (10 years)
This is why rate buydowns rarely make sense for 5-year terms when you factor in opportunity cost.
Builder rate buydowns (seller-paid)
In new construction, builders sometimes offer rate buydowns as a sales incentive — the builder pays the upfront cost, not you.
How builder buydowns work in Canada
- Builder pays the lender an upfront fee to reduce your rate for the first 1–3 years
- Your rate gradually increases to the full rate over the buydown period
- Common structures: 2-1 buydown (2% below market in year 1, 1% below in year 2, full rate in year 3)
Example: 2-1 builder buydown, $500,000 mortgage, market rate 5.00%
| Year | Rate | Monthly Payment | Savings vs Full Rate |
|---|---|---|---|
| Year 1 | 3.00% | $2,366 | $542/month |
| Year 2 | 4.00% | $2,624 | $284/month |
| Years 3–5 | 5.00% | $2,908 | $0 |
Total savings: $9,912 (paid by the builder)
Caution with builder buydowns
- You must qualify at the full rate under the stress test, not the bought-down rate
- The builder may have inflated the purchase price to cover the buydown cost
- After the buydown period, your payment increases — ensure you can afford the full payment
- Compare the buydown offer to a straight price reduction (which saves you interest for the entire amortization)
Cash-back mortgages: the reverse buydown
Some Canadian lenders offer cash-back mortgages — the opposite of a buydown. The lender gives you cash (typically 1–5% of the mortgage) in exchange for a higher interest rate.
| Feature | Rate Buydown | Cash-Back Mortgage |
|---|---|---|
| You pay upfront | Yes | No |
| Lender pays you | No | Yes (1–5% of mortgage) |
| Interest rate | Lower than standard | Higher than standard |
| Monthly payment | Lower | Higher |
| Best for | Minimizing monthly cost | Covering closing costs |
Cash-back mortgages are almost always a poor deal — the higher rate costs far more over 5 years than the cash you receive.
Summary
| Factor | Assessment |
|---|---|
| Does rate buydown work in Canada? | Yes, but less common and less formalized than the US |
| Typical cost | 1–1.5% of mortgage per 0.25% rate reduction |
| Break-even | Usually 5.5–7 years (exceeds most 5-year terms) |
| Best scenario | Long-term mortgage (7–10 years), large loan, plan to stay |
| Worst scenario | 5-year term with possibility of selling or refinancing |
| Better alternative for most | Put extra cash toward down payment or lump-sum prepayment |
For most Canadians on a standard 5-year fixed term, the math does not favour rate buydowns. The break-even typically exceeds the term length, and the upfront funds are better used as a down payment or prepayment. The exception is long-term fixed mortgages (7–10 years) or builder-paid buydowns where you bear no upfront cost.
