You’re not alone if you’ve considered the pros and cons of buying back pensionable service in your defined benefit pension plan. You may be able to buy back service for years you were on parental leave, ill, taking a sabbatical, etc. Your pension plan will confirm how much you can buy back.

The reason most people buy back service is if it will entitle you to a larger pension in retirement, and particularly if it helps you qualify for an unreduced (or less-reduced) pension more quickly.

DISCLAIMER: All information in this article about pension plan calculations is sourced from publicly available information – I do not guarantee the accuracy of this information, and this does not constitute advice about your pension. You should always confirm this information with your financial planner and pension plan. Bridge pension calculations are excluded for simplicity.

Buying back your pension is a nuanced decision. For those without any unused RRSP contribution room, this may require a transfer to the plan from your existing RRSPs and in some cases may even require withdrawing from your RRSPs.

You’ll want to consider the benefits you’d expect to receive from buying back:

  • Increase to base pension benefit.
  • Reduction to early retirement penalty.
  • Delegation of the management of retirement assets.
  • Ensuring income for your surviving spouse.

As well as the drawbacks:

  • Loss of some flexibility.
  • Potential decrease to spouse’s survivor income.
  • Potential decrease to estate value with early death.
  • The “return” on the money is capped.

Some pensions come with cost-of-living adjustments, and some don’t.

The simplest way to begin the assessment process is to understand how a pension is calculated, and how the pension may be reduced for early retirement. Each pension may be drastically different, and the calculation and potential benefit depends heavily on which plan you’re a member of.

To illustrate this, we’ll look at 3 different plans.

3 Pension Plans

These plans were picked at random.

Local Authorities Pension Plan (LAPP) in Alberta

As early as age 55, you can retire with an unreduced pension if your Age + Service Years equals 85. At 55, you need 30 years of pensionable service to qualify for an unreduced pension. At 60, you only need 25 years of pensionable service. (1) This is called an 85-factor.

Municipal Pension Plan (MPP) in BC

There are different rules for public safety workers vs. other employee classes. General employees have some very complex calculations right now, so I’ll exclude them. Public safety workers like firefighters in Group 2 qualify for an unreduced pension at either age 55, or if Age + Service Years equals 80 (80-factor).

University Pension Plan Ontario (UPP)

Some tranches of employees can get an unreduced pension if you reach age 60 and have 20 years of pensionable service. This is an 80-factor calculation. (3)

While you can retire at age 55, 80-factor does not apply. The reduction factor is based on age alone in that case, rather than age + service years. Normal retirement age is 65. (4)

The Reduction Factor

Each plan’s reduction factor calculation varies:

LAPP – reduced by 3% by the number of years it would take to reach either 85 factor or age 65.(5)

MPP – for public safety workers (Group 2), the reduction factor is usually 3% for each year you’re below age 55 or below 80-factor.(6)

UPP – Reduced by 5% for each year you are either below age 65 or below 80-factor and at least age 60.(3)

This reduction factor is calculated based on the base pension benefit, so we’ll need to know that too.

Pension Calculations

Not all pensions calculate the pension based on “highest consecutive salaries”, but it’s common. All 3 of these plans use consecutive salary calculations. Usually, the last years of the career are when earnings are highest.

LAPP

LAPP

MPP

Public safety workers in Group 2 (we will assume going forward that by MPP, I am referring to public safety workers, although there are multiple tranches with different calculations):

MPP 2

UPP

For service earned after January 1, 2025

UPP

You may have missed some key differences:

  • LAPP uses the 5-year average salary and YMPE.
  • MPP uses the current year YMPE and 5-year average salary.
  • UPP uses the 4-year average salary, and 4-year YAMPE (which is higher than the YMPE). 4-year salary is also likely to result in an increased benefit.

The point of this exercise is to demonstrate how different pension calculations can be and use this knowledge to interpret how the difference in plan calculations can affect a buyback decision.

Case Study

For the UPP example, credit earned prior to 2025 would use a different calculation. This overly complicates the example, so we’ll simplify. The YAMPE was introduced in 2024, so we’ll fill in the blanks for this example and use the YMPE for the missing years for our average.

Year YMPE YAMPE
2021 $61,600 $61,600
2022 $64,900 $64,900
2023 $66,600 $66,600
2024 $68,500 $73,200
2025 $71,300 $81,200
Current year YMPE $71,300
5-Year Avg. YMPE $66,580
4-Year Avg. YAMPE $71,475

Let’s run through a few scenarios to understand how the different pension calculations would work. Then, we’ll assess the expected increase to the pension benefit by buying back just 1 additional service year.

We’ll assume 3 identical employees who have the exact same service years, exact same age, and the same salary history. Their 4-year best average salary is $175,000, and their 5-year best average salary is $170,000.

Situation 1 – age 55, with 25 service years

Scenario Age 55 with 25 service years
Pension LAPP MPP UPP
Reduced pension $63,759 $72,523 $41,783
Buying back 1 year 8% 4% 4%

Findings:

  • Buying back with LAPP brings them closer to 85-factor, so their base pension benefit increases, and the reduction factor decreases.
  • The MPP public safety member has no reduction due to age, so their increase is due to 1 additional service year.
  • The huge difference in expected benefit with the UPP plan is due to the member being 10 years below age 65. Since 80-factor only kicks in at age 60, buying back a service year only increases the benefit – it doesn’t decrease the reduction.

Situation 2 – age 60, with 25 service years

Scenario Age 60 with 25 service years
Pension LAPP MPP UPP
Reduced pension $75,010 $72,523 $60,264
Buying back 1 year 4% 4% 4%

 Findings:

  • The LAPP member has already achieved 85-factor, so buying an additional service year only impacts the base benefit.
  • The MPP member didn’t experience a reduction, so buying an additional service year only impacts the base benefit.
  • The UPP member has already achieved 80-factor at age 60, so buying an additional service year only impacts the base benefit.

Situation 3 – age 60, with 19 service years

Scenario Age 60 with 19 service years
Pension LAPP MPP UPP
Reduced pension $46,746 $55,117 $58,015
Buying back 1 year 9% 5% 11%

 Findings:

  • Compared to Scenario 1, all 3 pension members are experiencing a more significant jump in expected benefit by buying back because their base number of service years is lower. In percentages, a jump from 19 to 20 is greater than a jump from 25 to 26.
  • Most interestingly, the UPP member could achieve a huge increase in benefit by buying back 1 year. At age 60, they’re eligible for a fully unreduced pension if they have 20 service years. The expected decrease in reduction combined with the increase in base benefit means 1 service year bought increases their pension benefit by 11% - that’s almost $6,300 per year.

Takeaways

This analysis is just the beginning to understanding the implications of a buyback but should help illustrate how the differences between each plan can affect the merits of buying back service years. The calculation method and unique factors around early retirement reductions can make a huge difference in the impact of buying back across plans.
