## How does construction loan interest work?

The interest-only approach is used to calculate construction loan interest rates, so the borrower only pays the interest during construction. Construction loans are riskier for lenders; hence they have higher interest rates than mortgage loans.

The interest is typically calculated on the outstanding loan and is charged regularly, such as monthly or annually. The lenderâ€™s rules and loan terms determine the interest rate; it can be either fixed or variable.

The lender releases payments in phases throughout construction. Each release calculates and charges interest on the outstanding loan balance.

Construction loans are short-term and must be refinanced into a long-term mortgage loan after completion. The borrower will start paying principal and interest at the market rate at this point.

## How to calculate construction loan interest rate

For calculating construction loan interest, you need to know the loan amount, interest rate, and the draw schedule. The draw schedule shows when each building stage will get cash. Each drawingâ€™s loan sum determines interest.

### Calculation example

Letâ€™s say you are building a new property with a total construction cost of \$500,000. You got a \$400,000 construction loan at 5%. Your draw schedule:

• Draw 1: \$100,000 for site preparation
• Draw 2: \$150,000 for foundation and framing
• Draw 3: \$100,000 for rough plumbing and electrical
• Draw 4: \$50,000 for exterior work
• Draw 5: \$50,000 for interior work

Multiply the loan sum at each draw by the interest rate to determine the construction loan interest.

For example, draw 1â€™s loan balance is \$400,000.

5% of \$400,000 is \$20,000.

To calculate the construction loanâ€™s total interest, calculate each drawâ€™s interest and add it together.

Before signing any contract:

• Consult with a mortgage expert or financial advisor.
• Shop around and compare offers from different lenders.
• Fully understand the loanâ€™s terms and conditions, including the interest rate, repayment schedule, and early repayment penalties.
