Chapter 14Terms, Amortization and Payment Structures

3 min read744 words Full contents

Term and amortization are different

The term is the period during which the current mortgage contract remains in force.

The amortization is the estimated period required to repay the mortgage in full based on the current balance, rate and payment structure.

A borrower may have:

A five-year term

A 25-year amortization

At the end of five years, the mortgage has not been fully repaid. The remaining balance must normally be renewed, refinanced, transferred or discharged.

FCAC confirms that terms may range from a few months to five years or longer, while amortization extends across the estimated repayment period.

How the major product features interact

FeatureWhat it controlsMain borrower consideration
TermHow long the current rate and contractual conditions applyRenewal timing, rate certainty and break risk
AmortizationEstimated time to repay the balancePayment size and total interest
Open mortgageAbility to repay without an ordinary prepayment penaltyUsually greater flexibility at a higher rate
Closed mortgageLimits repayment beyond contractual privilegesUsually lower pricing but potential break penalties
Convertible termPermits conversion from a shorter term to a longer term under lender rulesConversion rate and available terms are lender-specific
Standard chargeSecures the mortgage amount under the registered chargeMay be easier to transfer in some circumstances
Collateral chargeCan secure the mortgage and other obligations, potentially above the initial advanceFuture borrowing flexibility but possible transfer or legal complexity
Portable mortgageMay allow the existing mortgage to move to another propertyRequalification, timing and property approval still apply
Assumable mortgageMay allow an approved buyer to assume the existing contractLender approval and seller-liability issues require review
Interest-only structurePayment covers interest without scheduled principal reductionBalance normally remains outstanding and requires a clear exit

Open and closed structures, portability, assumability and standard versus collateral charges are contract features rather than universal rights. FCAC advises borrowers to verify the restrictions directly in the mortgage agreement.

Choosing a term

A shorter term provides an earlier opportunity to renegotiate but exposes the borrower to renewal risk sooner.

A longer term provides rate certainty for longer but may:

Carry different pricing

Reduce flexibility

Create a larger penalty if the mortgage is broken

Extend the period before the borrower can renegotiate without a break charge

The correct term should reflect the expected holding period—not merely a rate forecast.

A borrower likely to sell in two years should not assess a five-year mortgage as though the only relevant question were the first payment.

Amortization and total cost

A longer amortization generally:

Lowers the scheduled payment

Slows principal repayment

Increases total interest if other assumptions remain unchanged

A shorter amortization generally does the opposite.

FCAC’s current guidance warns that extending amortization to lower payments can add thousands or tens of thousands of dollars in interest.

The maximum available amortization depends on the transaction, mortgage-insurance rules and lender policy. The insured limits are addressed in Chapter 12.

Payment frequencies

Common payment frequencies include:

Monthly

Semi-monthly

Standard biweekly

Standard weekly

Accelerated biweekly

Accelerated weekly

A standard biweekly schedule divides the annual equivalent of 12 monthly payments across 26 payments. An accelerated biweekly schedule generally pays half the monthly amount every two weeks, producing the equivalent of approximately one additional monthly payment each year.

Accelerated biweekly payments

Assumptions

Mortgage principal: $500,000

Interest rate: 4.50%

Amortization: 25 years

Monthly payment: $2,767.36

Rate remains unchanged solely for illustration

No prepayments other than the accelerated schedule

Figures rounded

Variables

M = Monthly payment

SB = Standard biweekly payment

AB = Accelerated biweekly payment

Formulas

Standard biweekly payment = Monthly payment × 12 ÷ 26

Accelerated biweekly payment = Monthly payment ÷ 2

Calculations

SB = $2,767.36 × 12 ÷ 26

SB = $1,277.24

AB = $2,767.36 ÷ 2

AB = $1,383.68

Annual payments

Standard monthly or standard biweekly:

$2,767.36 × 12 = $33,208.32 per year

Accelerated biweekly:

$1,383.68 × 26 = $35,975.68 per year

Additional annual principal-and-interest payments:

$35,975.68 − $33,208.32 = $2,767.36

Result

Under the stated constant-rate assumptions:

Standard schedule balance after five years: approximately $438,796

Accelerated-biweekly balance after five years: approximately $423,313

Additional principal reduction: approximately $15,483

Approximate repayment period under the accelerated schedule: 21.7 years instead of 25 years

Interpretation

The benefit does not come from paying every two weeks by itself. It comes from paying more money each year.

Actual results will change when the mortgage renews at a different rate.

Prepayment features

A mortgage may permit the borrower to:

Increase regular payments

Make annual lump-sum payments

Double payments

Apply proceeds at specified times

The percentage, timing and unused-privilege rules vary by lender. These features matter only if the borrower is realistically likely to use them.

A 20% annual privilege offers little practical value to a borrower who cannot make additional payments. Conversely, a borrower expecting a business distribution, inheritance or property sale should compare these provisions carefully.

Portability, assumability and blend-and-extend

Portability

Portability may allow the borrower to move the existing balance, rate and remaining term to a new property.

It remains subject to:

Borrower requalification

New-property approval

Closing-date coordination

Additional-funds pricing

Product restrictions

Assumability

An assumable mortgage may allow another approved borrower to take over the contract. The legal consequences, including any continuing liability of the original borrower, should be reviewed with a lawyer.

Blend-and-extend

A lender may permit the existing rate to be blended with the rate on additional money or a new term. Calculation methods and eligibility are lender-specific.

These features should be treated as conditional options, not guaranteed escape routes.
