CMHC Insurance Calculator — Calculate Your Mortgage Insurance Cost — Canada 2026
Calculate CMHC mortgage insurance premium for Canadian home purchases with less than 20% down payment. See how down payment affects your insurance cost.
CMHC mortgage insurance is mandatory in Canada for home purchases with a down payment below 20%. This insurance protects the lender (not you) in case of default and adds a significant cost to your mortgage. The premium ranges from 2.8% to 4% of the mortgage amount and is typically added to your loan increasing your mortgage balance and monthly payments. Understanding this cost helps you decide between a smaller down payment now or saving more to avoid insurance entirely.
How much is CMHC insurance on $500000 home?
With 10% down ($50000) on a $500000 home: mortgage = $450000. CMHC premium = $450000 x 3.10% = $13950. Total mortgage becomes $463950. This adds approximately $65/month to your payment over 25 years. With only 5% down ($25000) the premium jumps to $475000 x 4% = $19000 adding approximately $89/month.

How This Calculator Works
This calculator uses the standard reducing balance method to compute your monthly payments. The formula takes your loan principal, annual interest rate, and tenure to calculate the exact Equated Monthly Installment (EMI) or payment amount. Each monthly payment consists of two components — principal repayment and interest charges. In the early months, a larger portion goes toward interest, but as your outstanding balance decreases, more of each payment reduces the principal. This is why making extra prepayments in the early years of your loan saves significantly more interest than prepaying later.
Tips to Get the Best Loan Deal
Always compare the Annual Percentage Rate (APR) rather than just the advertised interest rate, as APR includes processing fees, insurance charges, and other costs. Negotiate your processing fee — most banks will reduce or waive it if you ask. Choose the shortest tenure your budget allows since longer tenures dramatically increase total interest paid. Check prepayment terms before signing — RBI mandates zero prepayment penalty on floating rate home loans in India. Finally, maintain a credit score above 750 to qualify for the best rates from any lender.

How much is CMHC insurance on $500000 home?
With 10% down ($50000) on a $500000 home: mortgage = $450000. CMHC premium = $450000 x 3.10% = $13950. Total mortgage becomes $463950. This adds approximately $65/month to your payment over 25 years. With only 5% down ($25000) the premium jumps to $475000 x 4% = $19000 adding approximately $89/month.
Is it worth saving 20% to avoid CMHC?
Saving to 20% eliminates $14000-$19000 in CMHC premiums on a $500000 home. However if saving the extra 10-15% takes 2-3 years and home prices rise 5% annually the home now costs $525000-$578000. In rising markets buying sooner with CMHC insurance can be financially better despite the premium cost. Run the numbers for your specific market.
Can CMHC insurance be removed later?
No CMHC insurance cannot be removed once applied to your mortgage. Unlike US PMI which drops at 80% LTV Canadian mortgage insurance stays for the life of the mortgage term. The only way to eliminate it is to refinance once you have 20% equity but you will need to qualify again at current rates and pay refinancing costs.
How is EMI calculated?
EMI is calculated using the formula: EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 1200), and n is the tenure in months. This gives you the fixed monthly payment that covers both principal repayment and interest.
Should I choose a longer or shorter loan tenure?
A shorter tenure means higher EMI but significantly less total interest paid. For example, on a Rs 50 lakh loan at 8.5%, choosing 15 years over 20 years saves approximately Rs 12 lakh in interest but increases your EMI by about Rs 14,000. Choose the shortest tenure your budget allows.
Can I prepay my loan to reduce interest?
Yes, making prepayments is one of the smartest financial moves. RBI mandates zero prepayment penalty on floating rate home loans. Even small annual prepayments of Rs 1-2 lakh can save Rs 10-20 lakh in total interest and reduce your tenure by years.
What CIBIL score do I need for a loan?
Most banks require a minimum CIBIL score of 700 for loan approval. A score above 750 helps secure better interest rates. Scores between 650-700 may still get approved but at 0.5-1% higher rates. Below 650, approval becomes difficult with mainstream banks.
