Interest rates are a fundamental concept in the financial world. Whether you’re taking out a mortgage, applying for a credit card, or opening a savings account, interest rates impact how much you earn or pay over time. Let’s break it down to help you understand the role interest rates play in your financial decisions.
What is an Interest Rate?
An interest rate is the cost of borrowing money or the return on investment for saving money. It’s typically expressed as a percentage of the total amount borrowed or saved. For example, if you borrow $1,000 at a 5% annual interest rate, you’ll owe $50 in interest after one year.
Interest rates are set by lenders and influenced by the central bank, economic conditions, and market demand. They play a key role in the economy, affecting everything from personal loans to business investments.
Types of Interest Rates
1. Fixed Interest Rate
A fixed interest rate remains constant over the term of the loan or savings account. This provides predictability, making it easier to budget for monthly payments.
Example: Fixed-rate mortgages and certain personal loans.
2. Variable Interest Rate
A variable interest rate fluctuates based on market conditions or a benchmark rate like the Bank of Canada’s policy rate. This can result in lower payments initially but carries the risk of rate increases over time.
Example: Variable-rate mortgages and some lines of credit.
3. Compound Interest
Compound interest is calculated on the initial principal and also on the accumulated interest from previous periods. It can significantly increase the total amount over time.
Example: Savings accounts and investment growth.
How Are Interest Rates Determined?
Several factors influence interest rates, including:
- The Bank of Canada’s Policy Rate: The central bank sets the benchmark interest rate to guide borrowing and lending in the economy.
- Inflation: Higher inflation often leads to higher interest rates to control rising prices.
- Economic Growth: In a strong economy, interest rates tend to rise as demand for loans increases.
- Creditworthiness: Your credit score and history affect the rate you’re offered. Higher scores usually mean lower rates.

Why Are Interest Rates Important?
For Borrowers
Interest rates directly impact the cost of borrowing. A lower rate means smaller monthly payments and less total interest paid. For example:
- Mortgages: Even a 1% difference in your mortgage rate can save you thousands over the loan term.
- Credit Cards: High-interest credit cards can lead to significant debt if balances aren’t paid off monthly.

For Savers
Higher interest rates mean better returns on savings accounts, GICs, and other low-risk investments. Compound interest especially benefits long-term savings.
How to Calculate Interest
Interest calculations depend on the type of rate and loan or savings product. Here’s a simple example:
Simple Interest Formula
Simple interest = Principal × Rate × Time
Example: Borrowing $5,000 at a 4% annual rate for 3 years: $5,000 × 0.04 × 3 = $600 in interest.
Compound Interest Formula
Compound interest = Principal × (1 + Rate)^Time – Principal
Example: Saving $2,000 at a 5% annual rate compounded yearly for 2 years: $2,000 × (1 + 0.05)^2 – $2,000 = $205 in interest.

A: APR (Annual Percentage Rate) includes both the interest rate and any additional fees, giving you a clearer picture of the loan’s total cost.
