90-Day Plan to Cut Years Off Your Mortgage

Why 90 days matter

Lenders let you change payment amount or frequency once per mortgage year—often for free. Acting within one calendar quarter keeps the change “sticky” for the next 12 months, so extra dollars start compounding immediately. A 90-day window also gives you two or three pay-cheques to test-drive the higher amount before you lock in.

The three levers

Lever 1: Boost regular payment

Most big banks allow a 15–20 % increase to your set payment each year. On a $2 000 monthly core, that’s up to $400 extra that goes 100 % to principal.

Lever 2: Switch to accelerated frequency

“Accelerated bi-weekly” means half the monthly amount paid every two weeks. You make 26 half-payments = 13 full monthly payments in a year—one extra month without feeling it.

Lever 3: Drop lump sums

Prepayment privileges (typically 10–20 % of original balance annually) let you park a bonus, tax refund, or cash gift straight onto principal.

Build your 90-day calendar

• Day 1–7: Call your lender; confirm exact prepayment limits and fees (usually $0).
• Day 8–14: Pick one or two levers you can sustain.
• Day 15–30: Fill out the change form; set new payment to start next cycle.
• Day 31–90: Send any lump sums before year-end; track new balance online.

Simple dollar example

Mortgage: $400 000, 5 % interest, 25-year amortization.
Base monthly payment: $2 330.
Option A: Add $200 each payment → new $2 530.
Result: Paid off in 18 years, saves $78 000 interest.
Option B: Switch to accelerated bi-weekly $1 165 (half of $2 330) plus one $3 000 lump in year 1.
Result: Paid off in 19 years, saves $65 000 interest.
Pick the combo that fits your cash flow; both beat the original timeline.

When it makes sense / When it doesn’t

Makes sense

• You have at least 3 months of emergency savings.
• Your income is stable or rising.
• High-interest debt is already cleared.

Doesn’t make sense

• You carry credit-card balances at 20 %.
• You might move within 12 months (small prepayment room could be wasted).
• You’re relying on RRSP matching at work—do that first for free money.

Pros & Cons

Pros

• Own home years sooner.
• Save thousands in interest.
• Build equity faster for future borrowing power.
• Flexibility to stop extra payments if life changes.

Cons

• Higher monthly cash commitment.
• Money locked in home—less liquid.
• Opportunity cost if investments earn more than mortgage rate.
• Some lenders still cap total annual prepayments.

Eligibility quick-check

☐ Mortgage is past its closing date (open or closed).
☐ You have unused annual prepayment room.
☐ No arrears or late payments in last 12 months.
☐ TDS ratio stays under 44 % after payment bump.

Docs to prepare

• Last 2 pay stubs or Notice of Assessment.
• Current mortgage annual statement.
• Online banking login (to set up new payment).
• Lump-sum source: bonus letter, tax refund screenshot, etc.

Common mistakes to avoid

• Forgetting to label extra payments “principal only.”
• Missing the lender’s calendar year-end cut-off.
• Raising payments so high you re-borrow on credit cards.
• Ignoring life-insurance or disability coverage gaps.

Plain-English definitions

Amortization: Total time you’re scheduled to repay the full mortgage.
Prepayment privilege: Contract clause letting you pay extra without penalty.
Accelerated bi-weekly: 26 payments per year equals one extra monthly payment annually.
Principal: The actual dollars you borrowed, not the interest.

How to decide in 60 seconds

1. Check last mortgage statement—do you have 10 %+ prepayment room left this year?
2. Can you spare $100–$300 per payment without touching emergency fund?
3. If yes to both, call lender today; changes take <10 days to activate.
