"Affordable" at $3,125 a month: whose income is that 30% of?
Ottawa's $2.7-billion Toronto rental announcement reopened an old argument about the word affordable. The gap isn't the 30% — it's which income you take 30% of.
On August 5, the federal government announced up to $2.7 billion over three years to build more than 5,600 rental homes across Toronto, at least 1,800 of them affordable, supportive or rent-controlled. Within a day the loudest argument online wasn't about the money. It was about one word in the announcement: affordable.
The benchmark being defended is the standard one — housing costs at or below 30% of household income. Applied to average Toronto-area household income, that permits a rent of roughly $3,125 a month and still calls it affordable. A lot of renters read that number and did not recognize their own lives in it.
They're not wrong, and neither is the arithmetic. The problem is hiding in the two words nobody says out loud: which income, and whose.
$3,125 a month describes a $125,000 household
Run the definition backwards. Rent of $3,125 a month at exactly 30% implies a household earning $125,000 a year before tax. That's the household the standard is describing.
In Ontario, $125,000 sits at about the 64th percentile of household income. Roughly two in three Ontario households earn less than that — so a benchmark built on it describes a rent that most households, by construction, cannot reach. The Ontario median household income is $90,200. Thirty percent of that is $2,255 a month, nearly $900 below the headline figure.
You can check where any household lands with the household income percentile tool.
The average-versus-median trick
This is where the number comes from. "Average household income" usually means the mean, and income distributions have a long right tail — a small number of very high earners pull the mean well above the middle of the pack. Anchoring an affordability standard to the mean quietly moves the target upward, away from the household in the middle.
Thirty percent of the average income and thirty percent of the typical income are two different policies wearing the same number.
Neither figure is dishonest. But one of them describes a household that most renters would recognize, and one of them doesn't.
Then there's gross versus take-home
The 30% rule is applied to before-tax income, which is the second place the number drifts from lived experience. Nobody pays rent out of gross pay.
For a household earning $125,000 in Ontario in 2026:
- 30% of gross income: $3,125/month
- 30% of take-home, if that's one earner: about $2,240/month
- 30% of take-home, if it's two earners at $62,500 each: about $2,390/month
The same household, the same rule, and a swing of $700 to $900 a month depending on which income you measure. Run your own pair of numbers through the take-home pay calculator before accepting any percentage rule at face value.
What Toronto rents actually require
Against average Toronto rents, the picture is less bleak than $3,125 implies — which is its own argument for using a better benchmark:
- Bachelor, $1,491: needs about $59,600 of household income at 30% gross (~33rd percentile in Ontario)
- One-bedroom, $1,761: about $70,400 (~40th percentile)
- Two-bedroom, $2,045: about $81,800 (~46th percentile)
- Three-bedroom, $2,294: about $91,800 (~51st percentile)
Read that list next to the median household income of $90,200 and the real constraint comes into focus. A family needing three bedrooms in Toronto has to be at roughly the median Ontario household income just to clear the 30% line — and that's against average rents, not the ones on listing sites today. The households below the median aren't slightly short. They're structurally short.
Why the definition matters more than the dollar figure
When "affordable" is pegged to a moving market average, affordable units get cheaper only when the market does. That's the mechanism critics keep pointing at: a unit can satisfy the definition while being out of reach for the people the program is meant to serve. Definitions tied to median renter income, or to fixed dollar bands, behave differently — they don't rise just because the top of the market did.
That's a policy argument with real people on both sides of it, and it isn't settled by arithmetic alone. What arithmetic can settle is the smaller question: when someone says a rent is affordable, ask which income they took 30% of, and whether it was before or after tax. Those two answers move the number by close to a thousand dollars a month.
Set your own ceiling instead
Whatever the policy benchmark says, your personal one comes from your own fixed costs — the approach in how much rent can you actually afford. Start from take-home pay, subtract what you're already committed to, and let the percentage be an output rather than an input.
Quick answers
What income does a $3,125 rent assume? At exactly 30% of gross, it assumes a household earning $125,000 a year — roughly the 64th percentile in Ontario, meaning about two-thirds of Ontario households earn less.
Is 30% of income calculated before or after tax? Housing policy uses before-tax income. On a $125,000 household in Ontario, 30% of take-home is closer to $2,240–$2,390 a month — $700 to $900 less than the gross-based figure.
What household income does an average Toronto one-bedroom require? At $1,761 a month, the 30% rule implies about $70,400 of household income, around the 40th percentile in Ontario.
