Time does most of the work
Growth is earned on growth. The earliest dollars you put in have the longest time to compound, so they end up doing most of the work. Waiting doesn't just remove the contributions you skipped — it removes the years of growth those contributions would have earned at the end.
That is why the gap between starting now and starting in a few years is usually much larger than the money you didn't put in.
What this calculator shows
Enter a monthly contribution, the total number of years until you need the money, and how many years you wait before starting. The calculator compares starting now with starting later, for the same end date, and shows the cost of waiting in dollars. The chart shows the two paths over time.
Returns use the FP Canada 2026 projection guidelines and are shown after fees: Cautious 3.2 %, Balanced 4.5 %, Growth 5.1 % a year. You can change the return and the fee; a higher figure is an optimistic scenario, not a forecast.
Using the result
Starting small beats waiting to start big. If $100 a month is what fits today, starting with that and raising it later usually ends ahead of waiting until a larger amount fits. Where the money goes matters too — a TFSA, RRSP, FHSA or RESP can add tax savings or grants on top of the growth shown here.
Try it with your own monthly amount and the number of years you are actually thinking of waiting — the gap for your own numbers is more convincing than any example.
A rule of thumb
72 ÷ return = years to double. At 4.5 % a year after fees, money doubles about every 16 years. A dollar invested 32 years before you need it has time to double twice and becomes about $4. Wait 16 years, and the same dollar doubles only once — about $2. Waiting didn't cost one dollar; it cost the last doubling.
Common questions
Why is the cost of waiting so large?
Because the years you skip are the earliest ones, and early contributions have the most time to grow. The missing growth at the end is usually larger than the contributions you didn't make.
What return does the calculator use?
It starts from the balanced preset, 4.5 % a year after fees (FP Canada 2026 guidelines). You can choose cautious or growth, or set your own return and fee.
Is this a recommendation to invest?
No. It is an illustration of how timing affects growth. Which account and investment suit you depends on your situation — talk to a licensed advisor.
