Introduction

What do we need to know about investments and credit to make responsible decisions that meet our financial goals?

How might someone use different tools to help them understand how their investment or credit is changing over time?

Let’s find out together!

Investing

Investing is like saving although with generally more risk. Similar to savings, you put money aside for future goals or in case of an emergency. An investment is a product that people can buy from a financial institution that may grow in value, or could also decline in value.

When thinking about investments, someone might consider the following:

  • Security: Is this investment stable or is there potential to lose money?
  • Rate of return: What is the total amount of interest earned on the investment?
  • Time: How long do I need to keep and/or pay into my investment?

Types of investments

Investing can help you to grow your money, but not all investments are created equal. Each type of investment comes with its own level of risk—some are relatively safe and stable, while others carry the potential for higher rewards but also higher chances of loss.

Note: Each financial institution will have its own investments options and a variety of rates of return, so it is important to do your research. It is also helpful to learn relevant terms, so you can make well-informed financial decisions.

Explore the following vocabulary terms to learn more about a few types of investments and some of the accounts where they are held.

Press the following tabs to learn more about different types of investment products.

Stocks are shares or pieces of a public company that can be bought by an investor. They are an example of a very high-risk investment with a high rate of return. The money the investor makes on the stock depends on how that stock performs in the financial market. This means that if a stock is not performing well an investor can lose money, but if they do well an investor can make more money than expected.

Bonds are an example of a medium risk investment. Bonds are loans that investors give to a company or government with the promise of repayment and interest. Bonds usually allow you to get your money back plus interest. They have a lower rate of return than stocks and also require the investor to keep the money they have invested in a bond for a specific amount of time without taking it out.

A mutual fund is a type of investment that is shared by many investors. Mutual funds are an example of a medium risk investment. An investor will usually get their money back including interest on a mutual fund. Sometimes the financial institution will charge fees to manage the mutual fund.

A GIC (Guaranteed Investment Certificate) is a savings certificate that gains interest and has a set time before the investor can withdraw your money. GICs are an example of a low-risk investment. An investor will always get their money back with interest. However, the rate of return is low, and an investor cannot access their money for a set amount of time.

An ETF (Exchange-Traded Fund) is an investment fund that lets you buy a collection of stocks, bonds, or other investments in a single purchase. You can think of it like buying a variety pack instead of choosing just one item because you get a little bit of everything rather than putting all your money into one investment.

Press the following tabs to learn more about different types of accounts that can hold investments.

A TFSA (tax-free savings account) is a registered savings account that functions like an investment account. It can hold cash savings and investments (like GICs or mutual funds) that generate tax-free income.

Different accounts, such as a TFSA, RRSP, or RESP, can be thought of as investment “baskets” or “vehicles”, while different investments, such as GICs, mutual funds, and stocks, should be thought of as “investment products” that are placed inside the “baskets/vehicles”.

As you explore the following chart outlining various types of investments, consider the following questions:

  1. What do you notice about the level of risk and the rate of return for each?
  2. What are the pros and cons to each type of investment?
  3. What stands out to you most?

Record your thoughts using a method of your choice.

Note: These are only a few examples of types of investments. Each financial institution will offer its own investment options and a variety of rates of return.

Why might it be important to understand all the specific details of an investment before deciding to invest?

Investment risk and timelines

It is important to decide on a timeline when you are setting your financial goal and deciding on an investment.

Short-term goals are things you want soon, like art supplies or a game.

Mid-term goals are things you’ll need to save for a bit longer, like taking a special class or a fun outing with friends.

Long-term goals are things you want to have further in the future, like a car or post-secondary education.

Teacher Ravi says: Before making any type of investment, it is always important to consider the financial goal and do some research. This could mean speaking to a financial advisor or another type of financial planner and learning more about what works best for you.

Credit types

Credit is the ability to borrow money or access goods or services with the understanding that you'll pay it back at a later time, sometimes with interest.

Press the following tabs to learn more about the different types of credit.

A credit card is a plastic card that allows the cardholder to borrow money from their financial institution to pay for goods and services. Different credit cards have different credit limits (a maximum amount of money that can be borrowed). The borrowed amount must be paid back according to the rules set by the company.

If the credit card holder pays back the borrowed amount by the due date (typically the end of the month or 21 days after you receive your bill in Canada), they will not pay any extra fees. However, if they cannot pay the borrowed amount in full by due date, then they will be charged interest and late fees on the unpaid amount. The amount of interest charged depends on the interest rate. An interest rate is usually a percentage of the amount that is owed. Credit cards typically offer higher interest rates than other types of credit.

Some credit card companies provide cards that gather points or redeem rewards, but those cards may have special fees attached.

A line of credit is a type of loan that a financial institution agrees to lend you up to a pre-set amount. It’s like having a jar of money that you can borrow from when you need to. You may use as little or as much of the funds available up to that specific limit.

You can pay back the money you owe at any time, however, interest will be charged on top of the borrowed amount. And, unlike a credit card, if you take out some money, you start paying interest on what you borrowed right away.

Usually, the interest rate on a line of credit is lower than credit cards.

Some lines of credit require additional fees. For example, you may need to pay a registration fee.

Personal loans allow you to borrow a specific amount of money and pay it back over a set period of time.

You must pay back the full amount, including interest and any other fees, by making regular payments called installments.

Student loan application form

Did you know?

There are special credit options available for students in post-secondary education.

Student credit cards

Student credit cards allow people with little or no credit history to get approved while in school. They usually have lower credit limits, and do not require an annual (yearly) fee or a minimum annual income (amount someone makes yearly).

Student lines of credit

Students who are enrolled in a post-secondary institution may be eligible for a student line of credit to help pay for expenses like tuition and living costs. Student lines of credit typically offer lower interest rates than standard lines of credit and a more flexible repayment plan.

Student loans

In Canada, students who are continuing their education after high school may apply for a student loan called the Ontario Student Assistance Program (OSAP). Part of the loan is funded by the federal government and does not charge any interest. Another part of the loan is funded by the provincial government and may charge interest depending on the rules set by the province.

Simple and compound interest

Okay, so how does simple and compound interest factor in?

Simple interest is interest applied to the principal amount. Whether you are investing or borrowing, simple interest will grow on the principal amount only.

Compound interest is interest that is applied to the principal amount and interest along the way.

For savings and investments, compound interest helps you make more money at a faster rate. However, with debt (e.g., credit cards, loans) compound interest “compounds the interest” you owe and makes it more difficult to pay off.

Teacher Ravi’s investment options

Teacher Ravi is thinking of investing his money. He is considering three investments that earn interest. In these examples, the return on each investment comes from interest earned.

  1. An investment that applies simple interest at a rate of 6% interest per year.
  2. An investment that applies compound interest at a rate of 6% per year, compounded semi-annually.
  3. An investment that applies compound interest at a rate of 6% per year, compounded semi-annually, and with the option to set up a recurring payment. This means that Ravi can add more money to the principal amount every year. He chooses to add $100/year.

He wants to see what $100 invested in each account gives him in three years.

Try it!

Let’s calculate what each option will give him in three years.

For each of Ravi’s three options, use the following Interest Calculators to figure out how much his investment would increase after three years. When you are finished, press the Show Answer button to compare your calculations.

Option 1: $100 invested in an account that applies simple interest at a rate of 6% interest per year.

Option 2: $100 invested in an account that applies compound interest at a rate of 6% per, compounded semi-annually. Note that there are no recurring additions.

Option 3: $100 invested in an account that applies compound interest at a rate of 6% per year, compounded semi-annually, with a recurring payment of $100/year.

Note: Investments can generate returns in different ways, such as interest, dividends, or increases in value. In this example, Teacher Ravi is comparing investments that generate returns specifically through interest.

Let’s see what happens to Teacher Ravi’s investments over a 10-year period.
