What is a defined benefit pension plan?

A defined benefit pension (DB) pension plan promises to pay you a certain amount of monthly retirement income for life. The amount of your pension is based on a formula. The formula usually considers your earningsEarnings For companies, it’s the money they make and share with their shareholders. For investors, it’s the money they make from their investments.+ read full definition and years of service with your employer.

With most employer pension plans, both you and your employer contribute. Defined benefit pension plans put the responsibility on the employer for investing the contributions. This is to ensure there’s enough money to pay the future pensions for all plan members. If there’s a shortfall in the money needed, your employer must pay the difference.

Some defined benefit plans offer inflationInflation A rise in the cost of goods and services over a set period of time. This means a dollar can buy fewer goods over time.

In a defined contribution pension plan, the amount of your contribution is guaranteed, but not the amount of retirement income. Your retirement income amount may vary depending on how the pension funds are invested.

How do you become a member of a defined benefit pension plan?

It’s up to your employer to determine when you can become a member of a defined benefit plan. Many employers only offer the defined benefit pension plan to full-time employees. This could happen either when someone is hired or after a length of time (sometimes up to two years). Other employers leave the decision to join the plan up to you.

If you’re a part-time employee, you may be eligible to join too. Check with your plan administrator. In Ontario, plans must let you join if you have worked for your employer for 24 consecutive months and you have either:

  • worked at least 700 hours a year for the two previous consecutive calendar years, or
  • earned $18,000 or more in each of the two previous calendar years.

Defined benefit plans provide a pension that is funded in part by your employer. Because of this, it’s usually to your advantage to join the plan as soon you can — even if you are required to contribute, too.

How are your defined benefit pension contributions calculated?

Typically, your employer calculates your pension plan contributions each pay period and deducts them directly from your pay. Remember that:

  • Contributions are usually based on a percentage of your pay.
  • You can deduct these contributions on your taxTax A fee the government charges on income, property, and sales. The money goes to finance government programs and other costs.+ read full definition return.
  • Your employer may raise or lower the employee contribution rate depending on the funding requirements and terms of the plan.
  • These funding requirements are determined by actuaries who review the plan periodically, typically every three years.
  • Your employer also contributes to the plan. Your employer must fund at least half of the pension benefits you earn.

Some plans require you to be a plan member for a certain length of time before you are entitled to benefits. This is called vesting. The length of time varies by province. If you leave the plan before you are vested, you will get your own contributions back, with interest. In Ontario, vesting is immediate. This means you are always entitled to benefits related to your employer’s contributions.

How are your defined benefit pension plan earnings calculated?

Pension calculations are unique to each defined benefit (DB) plan. There are 3 main formula types, but there can be many variations to them:

  1. Final average earnings
  2. Career average earning
  3. Flat benefit


  1. Final average earnings

This formula is based on your average earnings in the years leading up to retirement. For example, in the five years before retirement.

Consider the formula below. It’s calculated using 2% multiplied by your average salary in the past five years. And then multiplied by your years as a plan member. If your average salary was $50,000 and you participated in the plan for 30 years your pension would be:

Benefit percentage 2%
Average salary $50,000
Years of plan membership 30
Formula calculation $50,000 x 2% x 30
Annual pension $30,000


  1. Career average earnings

This formula is based on your average earnings during the entire period you were a member of the plan.

In this example, the formula is calculated using 2% multiplied by your average salary in your career. And then multiplied by your years as a plan member. If your average salary was $30,000 and you participated in the plan for 30 years your pension would be:

Benefit percentage 2%
Average salary $30,000
Years of plan membership 30
Formula calculation $30,000 x 2% x 30
Annual pension $18,000

Compared to the final average earnings example, your annual pension amount is lower due to the career average salary being lower.

  1. Flat benefit

With this formula, your monthly pension benefit is equal to a fixed dollar amount for each year you are a member of the plan.

Sample formula would be $50 (the benefit amount) multiplied by your years as a plan member (30 years). If you participated in the plan for 30 years your pension would be:

Benefit amount $50
Years of membership 30
Formula calculation $50 x 30
Annual  pension $18,000 annually


Some plans increase pension payments to retirees each year to fully or partially match the rate of inflation. This is a highly valuable benefit because it helps your pension’s buying power keep up with rising prices over time.

What if you leave your defined benefit pension plan before you retire?

If you transfer the cash value out of your defined benefit plan, you give up your pension guarantee.

There are specific circumstances that can happen in your life that may impact your pension. For example, if you become disabled before retirement. Check with your plan administrator about the disability benefit rules that apply to your plan. If you are off work due to disability, you may be able to continue earning benefits under the plan.

What are multi-employer defined benefit pension plans?

Some defined benefit plans are sponsored by many employers. These are called multi-employer plans. They allow employees, who switch employers within the same industry, to maintain their pension coverage.

Plans can vary. Some multi-employer plans have straightforward plan formulas and operate much like single employer defined benefit plans. Others are complex, with elements of both defined benefit and defined contribution plans. These are often called target benefit plans.

How is your defined benefit pension plan protected?

When you contribute to a defined benefit plan, this helps keep your contributions safe.

If your employer goes bankrupt, they can’t continue making contributions. The pension plan may not have enough money to pay for the promised benefits. This is called an “underfunded” plan.

Underfunding is often related to the investment performance of plan contributions. For example, a fully funded plan can quickly become underfunded when its investments decline sharply in value. This could occur during an economic crisis or recession.

Because of the high cost that’s involved, employers are allowed to take several years to restore their plans to full funding. If they go bankrupt before this is completed, the plan will remain underfunded. Plan members and retirees may receive less than 100% of their promised pension.

Pension protection fund

Ontario is the only jurisdiction in Canada with a pension protection fund that can help when an employer goes bankrupt. The fund guarantees specified benefits up to $1,000 per month for members who meet certain age and service criteria (with some exclusions). Learn more about this fund and your pension rights
