Nova Scotia doesn't charge provincial sales tax on the premium, so there's nothing extra to pay in cash at closing for it.

Estimate only. Uses CMHC's published premium rates for purchases with 5% to 19.99% down, plus the 0.20% surcharge for amortizations over 25 years. Premiums are higher with a non-traditional (borrowed) down payment. Nothing you enter is saved or sent anywhere: it clears when you leave the page.

How this calculator works

  • The premium is a percentage of the loan, set by how much you put down: 4.00% with 5% to 9.99% down, 3.10% with 10% to 14.99%, and 2.80% with 15% to 19.99%.
  • A 30-year amortization (first-time buyers and new builds) adds 0.20% to the premium.
  • Homes priced at $1.5 million or more can't be insured, so they need 20% down.
  • The premium is usually added to the mortgage. Nova Scotia doesn't charge provincial sales tax on it.
