👴 Retirement Savings

How it works

Retirement saving works on two engines at once: the money you put in and the growth that money earns. Early on, your contributions do most of the work; later, growth takes over — the final decade often adds more than the first two combined. That is why starting early, even with small amounts, beats starting late with big ones.

This calculator projects what regular contributions will grow to by retirement at an assumed rate of return, optionally on top of savings you already have. For Canadians, the two main vehicles are the RRSP (tax deduction now, taxed on withdrawal) and the TFSA (no deduction, but growth and withdrawals are tax-free) — the math here is the same for both; the difference is tax timing.

The formula

Future value of monthly contributions: FV = PMT × (((1+r)^n − 1) / r), where PMT is the monthly contribution, r is the monthly return (annual return divided by 12, as a decimal), and n is the total number of months. Any existing savings are grown separately with P × (1+r)^n and added on. It assumes end-of-month contributions and a constant rate — real markets zigzag, but the long-run average is what matters.

Worked example

You contribute $500 a month for 30 years at an assumed 7% annual return. The monthly rate is 0.07/12 ≈ 0.005833 and n = 360. The growth factor ((1.005833)^360 − 1) / 0.005833 ≈ (8.116 − 1) / 0.005833 ≈ 1220. So FV ≈ 500 × 1220 ≈ $610,000 — from $180,000 of your own contributions.

Frequently asked questions

What return should I assume?
Many planners use 5–7% nominal for a balanced-to-growth portfolio over decades. Run the numbers at 5% too — if your plan still works at the lower return, it is robust.

RRSP or TFSA?
If your tax rate will be lower in retirement, the RRSP's deduction usually wins; if similar, they're close to equivalent. The TFSA's flexibility (withdrawals don't affect OAS clawback) makes it great too — many Canadians use both.

How much will I need?
A common rule of thumb is 25 times your desired annual spending (the "4% rule"), but it is only a starting point — your CPP/OAS, housing situation, and health all shift the real number. Use this calculator to see if your savings pace gets you there.

Read the big number in today's dollars

Retirement calculators produce impressive totals because they are stated in future dollars. A portfolio worth $782,824 in thirty years sounds abundant, but at 2 percent inflation it buys roughly what $432,174 buys today. That is the figure to compare against the life you are actually picturing. Two more pieces of context keep the number honest. First, this projection covers your personal savings only: Canada Pension Plan and Old Age Security will pay a base layer of income, so your savings need to fund the gap between those benefits and your spending, not your entire retirement. Second, real returns arrive in a jagged line, with deep drops along the way, and the order of those returns matters more the closer you get to spending the money.

A worked example

Start at 35 with $40,000 invested, add $6,000 a year, and earn 6.5 percent until 65. The original $40,000 grows to $264,575. The yearly contributions grow to $518,249. Together: $782,824. You personally paid in $220,000 of that, and growth supplied $562,824, more than two and a half times your deposits.

The RRSP adds a second engine. At a 30 percent marginal tax rate, each $6,000 contribution produces a $1,800 refund. Spend that refund and your true contribution was only $4,200 after tax. Reinvest it every year instead, and the refunds alone compound to $155,475 by age 65, a second retirement account built entirely out of tax you did not pay.

Where retirement plans leak

• Fees that look small. On the example above, investments netting 6 percent reach about $704,089, while investments netting 4.5 percent after a heavier fee load reach about $515,855. That gap, roughly $188,000, buys no extra service. It is simply growth redirected.
• Planning to replace all of your income. Most retirees spend noticeably less than they earned: the mortgage is gone, the children are launched, and work costs like commuting and payroll deductions disappear. Planning for your actual retirement spending usually shrinks the target to something reachable.
• Ignoring the government benefits. Taking CPP at 60 pays a permanently reduced amount, while delaying toward 70 raises it substantially. The default choice is rarely examined, and it is one of the largest levers in the whole plan.
• Spending the RRSP refund. Treating the refund as found money quietly cuts every contribution by your tax rate. The plan only works if the refund goes back in.

Frequently asked questions

How much do I actually need to retire in Canada?

There is no universal figure, because the target is your spending, not your salary. Many households spend far less in retirement once the mortgage and work costs are gone. Add up the retirement life you actually want, subtract what CPP and OAS will cover, and your savings only need to fund the difference.

Should I contribute to an RRSP or a TFSA first?

Compare your tax rate now with the rate you expect in retirement. If today's rate is higher, the RRSP deduction is worth more now, which favours the RRSP. If your income is modest today, the TFSA usually wins, since withdrawals are tax free and never reduce income tested benefits. Many people use both.

What rate of return should I assume when planning?

Less than you hope for. Balanced portfolios have historically returned roughly 5 to 6 percent a year before inflation over long stretches, with difficult decades mixed in. Run your plan at 5 percent, then again at 4 percent. If the plan only works at 8 percent or better, it is not a plan yet.

How much does starting at 45 instead of 35 cost me?

Roughly half the outcome. The example on this page, $40,000 plus $6,000 a year at 6.5 percent, reaches about $782,824 over thirty years. Run the identical plan over twenty years from age 45 and it reaches about $373,900. Catching up is entirely possible, but it takes larger deposits, not better timing.
