The monthly payment on a $500,000 mortgage is $2,765 at 4.49% with a 25-year amortization, before any insurance premium. This is the size where the down payment rules start to bite: a home bought with a $500,000 mortgage always costs more than $500,000, so part of its price falls in the band that needs a 10% down payment. The sections below work through that, then $400,000, which stays under the line with a minimum down payment, and $600,000.
Payments on $500,000 by rate
| Interest rate | 25-year amortization | 30-year amortization | Difference |
|---|---|---|---|
| 3.00% | $2,366 | $2,103 | $263 |
| 3.50% | $2,496 | $2,238 | $258 |
| 4.00% | $2,630 | $2,378 | $253 |
| 4.49% (average new uninsured 5-year fixed, July 2026) | $2,765 | $2,518 | $246 |
| 4.50% | $2,767 | $2,521 | $246 |
| 5.00% | $2,908 | $2,668 | $240 |

25 or 30 years
Spreading $500,000 over 30 years lowers the payment by $246 a month and adds $77,165 of interest at 4.49%: $406,541 in total against $329,376 over 25 years. Insured mortgages are limited to 25 years, except that first-time buyers and buyers of new builds can take 30 years since December 15, 2024 (Finance Canada), and CMHC’s premium for them is 0.20 points higher. With 20% or more down, the lender sets the maximum.
Prepaying works on either schedule. On the 25-year loan, $10,000 extra each anniversary saves $120,590 and a $250 monthly increase saves $52,025.
The minimum down payment on a $500,000 mortgage
For a home under $1.5 million, the minimum down payment is:
- 5% of the first $500,000 of the price.
- 10% of the part of the price above $500,000, for homes under $1.5 million.
Borrowing exactly $500,000 with that minimum means a home of about $527,778 and a $27,778 down payment. A flat 5% isn’t enough: on any price over $500,000 it comes in below what the two bands add up to. The loan needs default insurance; at CMHC’s rate for that loan-to-value it is 4.00% of the loan, $20,000.
| 10% down | 15% down | 20% down | |
|---|---|---|---|
| Home price | $555,556 | $588,235 | $625,000 |
| Down payment | $55,556 | $88,235 | $125,000 |
| CMHC premium | $15,500 (3.10%) | $14,000 (2.80%) | Insurance not required |
| Mortgage including premium | $515,500 | $514,000 | $500,000 |
| Average rate (insured or uninsured) | 4.05% | 4.05% | 4.49% |
| Monthly payment, 25 years | $2,726 | $2,718 | $2,765 |
| Monthly payment, 30 years | $2,471 | $2,464 | $2,518 |
The 30-year insured payments include the higher premium and apply only to first-time buyers and new builds.
What a lender tests on $500,000
With 20% down on a $625,000 home, the lender checks the payment at 6.49%: $3,346 a month rather than the $2,765 actually owed. Add the property tax and heating assumed in this site’s figures and the housing cost tested is $4,017 a month, which takes an income of about $123,600. At 10% down the loan carries a premium but is tested at 6.05%, and the income needed is about $120,800. The method is on the income-to-afford page.
Home prices a $500,000 mortgage lines up with

|---|---|---|---|---|

| Montreal (CMA) | Median single-family price, September 2026 | $635,000 | $596,500 ($96,500 more) | $508,000 ($8,000 more) |
| Ottawa | MLS HPI benchmark, August 2026 | $637,700 | $598,930 ($98,930 more) | $510,160 ($10,160 more) |
Halifax’s figure is the Nova Scotia board’s average for Halifax-Dartmouth, and Montreal’s is a median for single-family homes: neither is a benchmark, so each moves with the homes that happened to sell. The city pages break prices down by home type.
A $400,000 mortgage
$400,000 at 4.49% costs $2,212 a month over 25 years or $2,015 over 30, with total interest of $263,501 and $325,233 if the rate held. A 0.25-point lower rate would save $16,567 over 25 years, and $10,000 extra each anniversary $109,921.
Insured or not: the down payment decides
The same $400,000 loan can come from two quite different purchases:
- 20% down: a home of $500,000, no mortgage insurance.
- Minimum down payment: a home of about $421,053 with $21,053 down. That price is under $500,000, so 5% is enough, unlike the $500,000 loan above. Mortgage insurance is then required; CMHC charges 4.00% of the loan ($16,000), added to the mortgage.
Qualifying for $400,000 with 20% down takes about $99,800 a year.
A $600,000 mortgage
At 4.49%, $600,000 is $3,318 a month over 25 years, or $3,022 over 30. Over the full amortization the interest adds up to $395,251 (25 years) or $487,849 (30 years). With 20% down it’s a $750,000 home and an income of about $147,400; with the minimum down payment the home is about $638,889.
How much the rate matters at $600,000
On a loan this size a fraction of a point changes the total a lot. Compared with 4.49% over 25 years, a rate 0.25 points lower saves $24,851 and a rate half a point lower saves $49,390. Prepayment adds up too: $15,000 a year saves $164,882 and ends the mortgage 9.8 years early. The renewal calculator compares two offers for your own balance.
