How Variable Rates Work

Variable rate mortgages fluctuate with the Bank of Canada's overnight rate. When the BoC changes rates, your variable rate moves accordingly.

Variable Rate Structure

Prime Rate Connection

  • Variable rates quoted as prime minus/plus a discount
  • Example: Prime - 0.50%
  • Prime moves with Bank of Canada decisions
  • Your discount stays constant

Payment Types

Variable Rate, Variable Payment:

  • Payment changes when rate changes
  • Amortization stays stable
  • Cash flow varies

Variable Rate, Fixed Payment:

  • Payment stays the same
  • Portion going to principal changes
  • May hit trigger rate if rates rise significantly

When Variable Makes Sense

  • Rates expected to decrease
  • Large spread between fixed and variable
  • Planning to pay off or move within 3 years
  • Comfortable with payment fluctuations
  • Financial cushion for rate increases

Risk Tolerance Required

Variable rates require comfort with uncertainty:

  • Budget must handle higher payments if rates rise
  • Shouldn't be stretched at current rates
  • Emergency fund for payment increases

Variable Rate Advantages

  • Historically lower total interest paid
  • Lower starting rate typically
  • Smaller prepayment penalty (3 months' interest)
  • Benefit if rates decline
  • Flexibility to lock in fixed if needed

Variable Rate Risks

  • Payment increases when rates rise
  • Uncertainty in budgeting
  • Stress of rate decision announcements
  • May pay more if rates rise significantly

Alberta Economic Considerations

Alberta's economy can influence your variable rate decision:

  • Oil prices affect provincial economy
  • Job stability matters for payment flexibility
  • Strong economy may mean higher rates nationally

Converting to Fixed

Most variable mortgages allow conversion to fixed at any time:

  • Lock in at current fixed rate for remaining term
  • Usually no cost to convert
  • Provides escape if rates rise significantly

Your Variable Decision

Consider your risk tolerance, financial stability, and rate outlook. Variable can save money historically, but requires comfort with uncertainty. Get personalized advice based on your specific situation.
