At $90,000 in Ontario you keep $67,197 a year, or $5,600 a month. A $5,000 RRSP contribution cuts your tax by $1,482 and lowers take-home pay by $3,518.
The baseline before any contribution
On $90,000 gross, income tax is $17,034, CPP is $4,646 and EI is $1,123. The marginal combined rate is 29.65%, and that rate is the one an RRSP deduction works against.
Three contribution sizes
| RRSP contribution | Tax saved | Take-home drops by | Net after contribution | Monthly drop |
|---|---|---|---|---|
| $2,000 | $593 | $1,407 | $65,790 | $117 |
| $5,000 | $1,482 | $3,518 | $63,679 | $293 |
| $10,000 | $2,965 | $7,035 | $60,162 | $586 |
What the contribution costs after the refund
The money in the account is the full contribution. Your pay shrinks by less, because tax comes back. For $2,000 the take-home drop is $1,407, for $5,000 it is $3,518, and for $10,000 it is $7,035. The tax saved is 29.6% of each contribution, which matches the marginal rate at this income.
Why the saving is the same each time
Taxable income is $88,873 before any contribution. Even a $10,000 deduction leaves it at $78,873, which is still below the $117,045 line where the federal rate moves from 20.5% up. Ontario’s 9.15% rate also applies throughout, so every dollar contributed is worth 20.5% plus 9.15%, the 29.65% shown above.
How it would show on a cheque
If a $5,000 contribution came out evenly over 26 biweekly cheques, take-home would fall by about $135 per cheque, from $2,584 to $2,449. Many people instead claim the deduction at tax time, and then the saving arrives as a refund.
Limits to know about
The yearly RRSP limit for 2026 is $33,810, though your own limit depends on earlier years and is shown on your CRA notice. These figures treat each contribution as a deduction from taxable income and ignore employer matching, group plans and spousal contributions. The RRSP calculator lets you enter other amounts.
Withdrawals later
Tax on RRSP money is deferred. When it is withdrawn, it counts as income for that year. The numbers above show only the year of the contribution.

Where do these figures come from?
These figures are calculated with the same engine as our take-home pay calculator and the 2026 tables from the Canada Revenue Agency and the provinces. Only pay is counted, with no RRSP, credits or benefits unless the text says so.
