# Reduced Hours Pay Calculator: Four-Day Week and Leave

> See what a four-day week, reduced hours or unpaid leave really costs after tax, CPP and EI in your province: gross loss versus net loss, per day and week.

Go from five days to four on an $80,000 salary in Ontario and you give up $16,000 of pay before tax. Your take-home pay drops by only about $10,390 a year, because less income tax, CPP and EI come off the smaller cheque. That works out to roughly $200 per day off after tax. All figures are 2026 estimates.

Enter your pay, pick a four-day week or a stretch of unpaid leave, and see how your province stacks up against the rest.

## How much take-home pay do I lose on a four-day week?

A 20% pay cut on $80,000 in Ontario costs about $10,390 in take-home pay. That's 65% of the $16,000 you give up before tax, since the smaller cheque carries less deduction. Where you live moves the answer a bit, because provincial rates and credits differ.

| Province | Pay lost before tax | Take-home pay lost |
| --- | --- | --- |
| Quebec | $16,000 | $9,500 |
| Ontario | $16,000 | $10,390 |
| Alberta | $16,000 | $10,425 |

## Why is the loss smaller than the pay cut?

The dollars you stop earning were the ones taxed at your highest rate. On the Ontario example, income tax falls by $4,683, CPP by $847 and EI by $80. Pay level changes the split: at $150,000 you lose about 57 cents of take-home pay for each lost dollar, and at $50,000 it's 73 cents.

## What does a month of unpaid leave cost?

Four weeks of unpaid leave on an $80,000 salary removes $6,154 of pay and about $4,142 of take-home pay, or $207 for each day off. You feel 67% of the lost pay, a bit more than the 65% on a four-day week. Unpaid leave is a different thing from EI or parental benefits, which have their own rules.

## Does an RRSP contribution change the answer?

Yes, a fixed RRSP contribution makes the cut hurt a little more. With $8,000 going into an RRSP each year, the same four-day week costs $10,743 in take-home pay. The deduction was already sheltering part of the income you're losing, so the tax saved by the cut drops to $4,330. Check your room first on the [RRSP calculator](https://tax-services.ca/calculators/rrsp-retirement/rrsp-calculator). If money gets tight, you can trim the contribution after the change and rerun the numbers with the lower amount.

## What does this estimate leave out?

It skips benefits, employer pension matching, bonuses tied to salary and income-tested credits like the Canada Child Benefit, which can go up when your income goes down. Lower CPP contributions also mean a slightly smaller pension later (see the [Canada Revenue Agency: CPP contribution rates](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/payroll-deductions-contributions/canada-pension-plan-cpp/cpp-contribution-rates-maximums-exemptions.html)). For your real cheque, run the [take-home pay calculator](https://tax-services.ca/calculators/payroll-salary/take-home-pay-calculator) at the new salary and compare it with the [Canada Revenue Agency: payroll deductions tables](https://www.canada.ca/en/revenue-agency/services/forms-publications/payroll/t4032-payroll-deductions-tables.html). Weighing a raise instead? Try the [salary increase calculator](https://tax-services.ca/calculators/payroll-salary/salary-increase), or work backwards from a target cheque with the [net to gross calculator](https://tax-services.ca/calculators/payroll-salary/net-to-gross).
