Two people can earn similar incomes and still finish with very different balances because one started contributing a decade earlier. That is arithmetic, not a moral ranking. If you are already 35, raise the contribution rate — do not sit with the guilt.
$300 a month at 7%: side by side
Friend A starts at 25. Friend B starts at 35. Both invest $300 at month-end. Both stop adding at age 60. Return assumption: 7%/year compounded monthly.
| Age | A (start 25) | A cash in | B (start 35) | B cash in |
|---|---|---|---|---|
| 30 | $21,500 | $18,000 | — | — |
| 35 | $51,900 | $36,000 | $0 | $0 |
| 40 | $95,100 | $54,000 | $21,500 | $18,000 |
| 50 | $243,000 | $90,000 | $95,100 | $54,000 |
| 60 | $540,300 | $126,000 | $243,000 | $90,000 |
At 60, A is ahead by about $297,000 while only contributing $36,000 more in cash ($126k vs $90k). Most of the gap is compounding on the early years, not the extra deposits alone.
What a later starter can do
To finish near A’s ~$540,300 at 60 while starting at 35 under the same 7% assumption, B needs about $667/month — more than double $300. Other paths from 35 to 60 under the same return assumption:
- $400/month → ~$324,000
- $500/month → ~$405,000
- $600/month → ~$486,000
Time is the early starter’s lever; contribution rate is the later starter’s. Raises, bonuses, and paid-off loans should hit the automatic transfer before they disappear into lifestyle.
Canadian levers that change the catch-up story
- TFSA / RRSP room: unused room is a catch-up tool—confirm your personal room with the CRA (TFSA) and your RRSP deduction limit on CRA notices. Filling room with a higher contribution rate matters more than hunting a hot stock.
- Workplace match: unmatched free money is often the first place to increase contributions.
- Fees: a 0.6% MER gap compounds for decades — see ETF vs mutual fund.
What this comparison leaves out
- Returns are not smooth 7%. Sequence of returns near retirement can matter more than the average.
- Taxes, inflation, and fees are ignored here.
- Someone who could not invest at 25 because of debt or low income is not “behind morally” — they need a cash-flow plan now.
- Working a few years longer can close gaps that feel impossible with contributions alone — see retire at 60 vs 65.
Questions before you change your contribution
- What monthly amount can I automate after cash and high-rate debt are handled?
- If I am catching up from a later start, am I raising contributions — or only feeling guilty?
- Would a 20% market drop make me stop? If yes, rebuild cash or lower stock risk before increasing the transfer.
- Which account (TFSA / RRSP / taxable) gets the next dollar?
What to do next
- Automate a contribution you can keep during an ordinary bad month.
- Increase it when income rises (even $50 steps count).
- Keep an emergency fund so you are not forced to sell.
- Re-run the projection annually instead of replaying age regret.
