Retirement planning combines a target number, the right account type for your country, and the compounding math that gets you there. This guide organizes every retirement tool on MyCalcKit around those three questions.
Retirement Accounts at a Glance
| Country | Primary Account(s) | Key Feature |
|---|---|---|
| USA | 401(k), Traditional/Roth IRA | Employer matching on 401(k); Roth IRA grows and withdraws tax-free |
| Canada | RRSP, TFSA | RRSP defers tax now; TFSA never taxes growth or withdrawals |
| Australia | Superannuation (Super) | Compulsory 12% employer contribution, concessional tax rate |
| UK | Workplace pension, Cash/Stocks & Shares ISA | Pension gets tax relief on contributions; ISA is fully tax-free but funded from taxed income |
For current US 401(k) contribution limits, see the IRS's own page.
The common thread across every country: tax-advantaged accounts consistently beat an equivalent taxable account over a multi-decade horizon, simply because avoided or deferred tax compounds alongside your investment returns. Which specific account to prioritize first still depends heavily on your current tax bracket versus your expected tax bracket in retirement — see the country-specific guides below for the actual decision framework.

The traps that catch even careful savers
- Starting the compound interest clock late. Time in the market matters more than timing contributions perfectly; an earlier, smaller contribution often outgrows a later, larger one.
- Ignoring employer matching. Not contributing enough to get a full employer match (where offered) leaves free money on the table.
- Treating all tax-advantaged accounts as interchangeable. RRSP vs TFSA, or 401(k) vs Roth IRA, have different tax treatment that matters based on your current vs. expected future tax bracket.
What starting 10 years earlier is actually worth
Take someone contributing $500/month at an average 7% annual return (a commonly used long-term market assumption) from age 25 to 65 — 40 years. They end up with roughly $1,312,000. Now take an identical $500/month contribution starting at 35 instead, running for 30 years to the same age 65: roughly $610,000.
The gap is about $702,000 — and the striking part is where that gap actually comes from. The earlier starter only contributed $60,000 more in total (10 extra years at $500/month). The remaining roughly $642,000 of the difference is pure compounding, earned by money that simply had a decade longer to grow. This is the concrete version of "time in the market beats timing the market" — the cost of waiting isn't the contributions you miss, it's the growth those contributions would have generated compounding on top of itself for years afterward.
Frequently Asked Questions
Where should I start planning for retirement?
Start with How Much Do You Actually Need to Retire to set a target, then the Retirement Calculator to see if your current contributions are on track.
Which retirement account should I prioritize?
This depends on your country and tax situation. See RRSP vs TFSA for Canada, or check current 401(k) contribution limits for the US.
Is a tax-advantaged account always better than a regular savings account for retirement?
Almost always, yes, over a multi-decade horizon — the tax saved or deferred compounds alongside your investment returns, which consistently outperforms an equivalent taxable account holding identical investments.
How much does starting retirement savings 10 years late actually cost?
At $500/month and a 7% average return, starting at 25 instead of 35 results in roughly $702,000 more by age 65 — even though the earlier starter only contributes $60,000 more in total. The rest comes purely from an extra decade of compounding.
