For: Single Canadian renter (32), saving for a first home while keeping retirement on track
Should a Canadian first-time buyer fill the FHSA before the RRSP? This scenario shows when FHSA-first usually leaves more retirement flexibility, when.
For: Single Canadian worker (35), renter, deciding whether RRSP or TFSA should get the next retirement dollar
For a Canadian renter saving for retirement, TFSA usually comes first when flexibility matters most, while RRSP starts to pull ahead once income and tax.
Yes—on this retirement-only proxy, the couple can reach Coast FIRE at 45, but the lower-return margin is thin. The comparison asks whether they can stop voluntary retirement contributions at 45, 48, or 50 and still fund A$5,500/month from age 67 to 92. Contributions fall to zero from the tested age onward.
The couple are 36, renting, and have A$120,000 saved. The model puts A$90,000 into a conservative retirement-pot proxy and holds A$30,000 outside the projection as accessible cash. That split prevents the emergency reserve from inflating the Coast FIRE result. It does not create a pre-60 early-retirement bridge: the couple keep working and cover current living costs from income after they coast.
The research baseline is A$160k-A$240k of household gross income, roughly A$10.6k-A$15.1k/month after tax. A comfortable but not extravagant renting budget is about A$5.2k-A$7.6k/month, leaving an estimated A$3k-A$7k/month saving range. These presets use A$6,000/month of voluntary retirement investing until the selected Coast FIRE age. That contribution stays flat in today's dollars: the model does not add salary-linked increases, bonuses, or irregular top-ups.
All figures are in today's AUD. Each Coast FIRE age uses the same starting assets, retirement spending, and retirement dates. The return and stopping age change, and each row assigns excess age-92 capital to an explicit late-life care and estate provision rather than leaving a very large unallocated balance in the projection.
All nine tests support the A$5,500 target while leaving at least five years of modelled retirement spending after the age-92 provision. At 45, the lower-return case supports up to A$5,733/month, only A$233 above the target, and has no separate provision. The later checkpoints fund larger lower-return provisions—A$300,000 at 48 and A$800,000 at 50—while keeping the monthly target inside the same end-buffer boundary.
“Room” is the highest modelled monthly retirement spending that still leaves five years of that spending at age 92 after the stated provision. That five-year reserve is a deliberately conservative planning choice, not evidence that A$6,000/month is the only suitable contribution or a suggested budget.
The age-45 central case reaches about A$1.74 million at retirement: A$90,000 of opening assets plus A$648,000 of contributions and about A$997,000 of pre-retirement compounding. That is a mechanical result of smooth 3.2% real growth, not a forecast. The provisions make the use of projected upside explicit; they can represent later-life care, estate goals, or giving, and should be replaced with the couple's own goal rather than treated as a required bill.
Working-life rent, cars, relocation, travel, and other spending are outside this retirement-only proxy. The couple must cover them from wages and separate sinking funds without drawing from the modelled pot. If A$6,000/month is not sustainable after those costs, the relevant Coast FIRE age moves later.
This page uses a deliberately narrow definition: the modelled retirement pot can compound from the tested age to 67 with no further voluntary contributions, then support the planned retirement spending through 92, the stated late-life provision, and a five-year end buffer. It does not mean the couple can stop working at 45, 48, or 50.
The proxy is conservative in two ways:
Only A$90,000 of the couple's A$120,000 starting savings counts toward retirement; the A$30,000 accessible reserve is excluded from every result.
The model does not add compulsory employer super at any age. If the couple remain employed after reaching Coast FIRE, future super guarantee contributions would be additional to this projection.
The trade-off is that one combined retirement pot cannot prove where money sits. Before treating a checkpoint as actionable, the couple should list current super separately from non-super investments and keep the A$30,000 reserve—or a larger amount based on their risks—accessible.
Stopping at 45 gives the pot the longest time to compound, but it also removes five years of A$6,000 monthly contributions compared with stopping at 50. In the lower-return case, the monthly room is only A$233 above the target and there is no separate late-life provision, so a modest cost increase or weaker outcome could erase the margin.
Three more years of contributions add A$216,000 before investment growth. In the lower-return case, the plan supports the A$5,500 target, a A$300,000 age-92 provision, and about A$852,000 remaining afterward.
Two further years add another A$144,000 before growth. In the lower-return case, the age-92 provision rises to A$800,000, with about A$785,000 still remaining. The larger provision—not maximum monthly spending—is the reason to wait in this comparison, and it postpones the lifestyle benefit of switching off voluntary retirement investing.
This is a child-free renting base case. It does not include childcare, parental-leave income loss, family benefits, a home deposit, or mortgage costs. Those inputs depend on household income, care days, subsidy eligibility, leave length, return-to-work timing, and the property decision. If any is likely, add it before accepting the Coast FIRE age; do not treat the A$30,000 reserve as a substitute for a funded multi-year change.
The projections also use smooth annual returns. They do not model a market crash or the order in which good and bad years arrive.
Start with the latest age you would genuinely accept, then compare its lower-return row.
Replace the A$90,000 modelled opening pot with your current retirement-dedicated assets, keeping accessible emergency cash outside it.
Change A$6,000 to the amount you can sustain after rent and normal living costs.
Replace the age-92 provision with a care, giving, or estate goal that is meaningful to you; use zero if you do not want a separate goal.
Add childcare and reduced-work effects as separate entries only when you have credible care-day, subsidy, leave, and return-to-work assumptions.
If buying is likely, add the deposit and purchase costs as one-offs plus the ongoing housing-cost change. Home equity is not counted unless you also model a future sale.
Super is generally inaccessible before 60 for this couple: Coast FIRE is not early retirement. They still need wages or accessible non-super assets for any period before super can be accessed.
Age Pension is not included: the outcome does not rely on a future means-tested payment that could be reduced or zero for a higher-asset couple.
Returns are real, not nominal: the 2.6%-4.3% range is after inflation and sits within the research range for a diversified long-term portfolio.
Recheck after major life changes: a home purchase, child, reduced-work period, or large rent increase can move the credible Coast FIRE age.
This scenario is educational, not personal financial advice. It simplifies taxes, benefits, and portfolio setup so you can stress-test the decision before speaking with a qualified professional.
