Can You Afford to Live on One Income?
The Real Math: Second Income vs Staying Home
| Factor | Working (2nd Spouse) | Staying Home |
|---|---|---|
| Second gross income | $45,000 | $0 |
| Income tax (incl. CPP/EI) | -$10,000 | $0 |
| Childcare (2 kids) | -$12,000 to -$24,000 | $0 |
| Commuting | -$2,400 to -$6,000 | $0 |
| Work clothes/lunches | -$1,800 to -$3,600 | $0 |
| Convenience spending (takeout, cleaning) | -$2,400 to -$4,800 | $0 |
| Net financial benefit of working | $4,000 to $16,000 | $0 |
| Lost Canada Child Benefit (higher income) | -$2,000 to -$5,000 | Gets full CCB |
| Adjusted net benefit | -$1,000 to $14,000 | $0 + more CCB |
In many cases, the second income adds only $0-$15,000 after all costs. If the value of staying home (childcare quality, stress reduction, schedule flexibility) exceeds this amount, one income makes financial sense.

Canada Child Benefit by Income

|---|---|---|
| Under $36,502 | $7,787/year ($649/mo) | $6,570/year ($547/mo) |
| $50,000 | ~$6,800/year | ~$5,700/year |
