Paycheque Parking: Use Cash Flow to Lower Interest

What paycheque parking really is

Paycheque parking means directing your entire net pay onto your mortgage (or its re-advanceable line) the same day it arrives. You treat the credit line like a temporary chequing account. Bills and groceries are paid from the same line later in the month. Every extra day the balance stays lower, less interest accrues. No extra income required—just smarter timing.

How the hack lowers interest

Interest on most Canadian mortgages is calculated on the daily outstanding balance. A $400,000 balance at 5 % costs about $55 every day. Park $6,000 of pay for 15 days and the average balance drops by roughly $3,000. That tiny swing saves about $8 a month—$96 a year—without spending a dime less. Repeat monthly and the snowball grows.

Step 1: Switch to a re-advanceable mortgage

You need a mortgage that includes a home-equity line of credit (HELOC) that you can pay down and re-borrow instantly. Big-bank versions go by names like “All-in-One” or “Step.” Confirm there are no fees for deposits or withdrawals.

Step 2: Deposit pay into the HELOC sub-account

Set payroll to deposit straight into the HELOC. If HR can’t split deposits, move money manually the day it lands. The instant reduction in principal starts saving interest that night.

Step 3: Pay bills from the same HELOC

Use the attached debit card or online banking to pay utilities, credit cards, and even the mortgage payment itself. Track spending so the balance never drifts higher than your monthly income.

When it makes sense / When it doesn’t

Makes sense

• You have positive cash flow every month.
• You’re disciplined with plastic—no new consumer debt.
• Your mortgage rate is higher than the HELOC rate.

Doesn’t make sense

• Your spending always exceeds income.
• The lender charges transaction fees or higher HELOC rates.
• You need a static budget—variable balances create anxiety.

Pros and cons

Pros

• Automatic interest savings every day.

• Pays mortgage off years early with same income.

Cons

• Requires re-advanceable mortgage; not all qualify.
• Easy to overspend when credit feels available.
• Variable HELOC rate can rise above mortgage rate.
