Trigger Rate vs Trigger Point: What Is the Difference?
A trigger rate is an interest rate: the point where your fixed variable payment stops covering interest. A trigger point is a dollar balance ceiling that comes later, if the balance keeps growing after that. They are not the same moment, and this page explains exactly how they relate.

What is the difference between a trigger rate and a trigger point?
A trigger rate is an interest rate, the point where your fixed variable mortgage payment stops covering that month’s interest. A trigger point is a different kind of thing entirely. It is a dollar balance ceiling, set out in your mortgage contract, that your growing balance can reach later if nothing changes after the trigger rate is hit.
The two terms get used as if they describe the same event. They do not. A trigger rate is a rate. A trigger point is a balance.
One happens first and describes what is going on inside your monthly payment. The other happens later, only if at all, and describes your total outstanding balance against a ceiling written into your contract.
We cover the mechanics of the first term in full on our page explaining what a trigger rate is. This page builds on that explanation rather than repeating it, so read that one first if the trigger rate itself is still unclear.
| Trigger rate | Trigger point | |
|---|---|---|
| What it is | An interest rate | A dollar balance ceiling |
| What kind of thing it measures | The split inside a fixed payment between interest and principal | The total unpaid balance against a contractual limit |
| When it happens | Occurs first, the moment interest claims the whole fixed payment | Occurs later, only if negative amortization keeps adding to the balance after that |
| What changes | The principal portion of the payment falls to zero; the balance stops shrinking | The balance has grown to the ceiling; the lender is required to act |
| What the lender does | Nothing, on its own | Typically asks for a higher payment, a lump sum, or conversion to a fixed rate |
The citable fact: A trigger rate is the interest rate where a fixed variable payment stops covering interest, and a trigger point is the later dollar balance ceiling that forces lender action if negative amortization keeps building after that.
Why does the trigger point come after the trigger rate, not instead of it?
The trigger point cannot exist without the trigger rate coming first. A mortgage has to pass its trigger rate, so unpaid interest starts adding to the balance, before that balance has any chance of climbing toward a contractual ceiling. The two are stages in one sequence, not two names for the same event.
Reaching the trigger rate is a single moment. It is the specific month the principal portion of the payment lands at zero, and the loan stops shrinking.
Reaching the trigger point, if it ever happens, takes longer. How long depends on how far past the trigger rate the interest rate climbs, and for how long it stays there, because that combination decides how quickly unpaid interest piles onto the balance.
The citable fact: A mortgage must pass its trigger rate before negative amortization can begin, and only sustained negative amortization after that point can eventually reach a trigger point.
What is negative amortization, and how does it connect the trigger rate to the trigger point?
Negative amortization is what fills the gap between the trigger rate and the trigger point. Once interest owed exceeds the fixed payment, the shortfall is added to the balance instead of collected, so the balance grows with each payment instead of shrinking. It is the mechanism that turns one event, the trigger rate, into a path toward another, the trigger point.
Before the trigger rate, interest and principal share the fixed payment between them. At the trigger rate, principal’s share has fallen to zero and interest has claimed the whole payment.
Past the trigger rate, interest owed is larger than the payment itself. The amount the payment cannot cover does not disappear; it gets added to the balance, which is the definition of negative amortization.

The figures above are round numbers chosen to show the mechanics. They are not tied to any rate and they are not a quote.
The citable fact: Negative amortization is the growth in mortgage balance that happens once interest owed exceeds the fixed payment, and it is the mechanism that links the trigger rate to the later trigger point.
What does negative amortization actually mean for a borrower, month to month?
Negative amortization means three things happen together. The balance grows instead of shrinks, the time left to pay off the mortgage stretches beyond the original schedule, and any equity gain built from regular payments slows down or reverses. None of those three is optional once the fixed payment stops covering interest.
A mortgage balance normally falls a little with every payment. Under negative amortization that direction flips, and the balance climbs instead, even though the borrower is still paying on time, every month, in full.
The amortization schedule the mortgage was set up on no longer matches reality. The borrower is not paying off the loan on the original timeline; they are further from paid off than the schedule says, and the gap widens the longer the rate sits above the trigger rate.
Equity built through regular payments slows for the same reason. Where a portion of every payment used to reduce the balance and build equity, that portion is now zero or negative, so equity growth from paydown pauses or reverses for as long as the condition lasts.
The citable fact: Negative amortization grows the balance, stretches the payoff timeline beyond the original schedule, and slows or reverses the equity a borrower builds through regular payments.
What is the contractual ceiling that defines my trigger point?
Your trigger point is whatever balance ceiling your own mortgage contract sets out, and that figure is written into your commitment rather than fixed by any general rule. Market practice commonly describes the ceiling as the original principal amount you borrowed, but that is a common description of practice, not a confirmed universal threshold. Check your own contract rather than assuming it.
Lenders build the trigger point into the mortgage documents at the outset, alongside the trigger rate itself or the formula used to calculate it. The exact wording varies by lender.
Because the ceiling comes from your contract, it is specific to your mortgage and your original loan amount. There is no standard percentage above the balance, and no standard dollar figure, that applies the same way across every lender.
The ceiling is the original principal amount. That is the practical difference between the two thresholds: the trigger rate is where your payment stops covering interest, and the trigger point is where the balance has climbed back to what you first borrowed.
The citable fact: A trigger point ceiling is set by the individual mortgage contract, and while market practice commonly describes it as the original principal amount, that description is not a confirmed universal rule and should be checked against the borrower’s own documents.
Do adjustable-payment variable mortgages or fixed-rate mortgages ever reach a trigger point?
No, neither one does. A trigger point can only follow a trigger rate, and only a fixed-payment variable mortgage has a trigger rate to begin with. An adjustable-payment mortgage changes the payment itself with prime, and a fixed-rate mortgage never moves at all, so neither product has a mechanism for interest to outgrow the payment.
A fixed-payment variable mortgage, commonly called a VRM, holds the payment level while the rate moves, which is the entire reason a trigger rate and a trigger point can exist on that product.
An adjustable-payment mortgage, commonly called an ARM, recalculates the payment itself every time prime moves. Interest can never outpace a payment that is always being reset to match it.
| Mortgage type | Can a trigger rate occur | Can a trigger point occur | Why |
|---|---|---|---|
| Fixed-payment variable (VRM) | Yes | Yes | Payment stays fixed while the rate floats, so interest can eventually outgrow the payment and negative amortization can build toward the ceiling |
| Adjustable-payment variable (ARM) | No | No | The payment itself is recalculated with every prime move, so interest never outpaces it |
| Fixed-rate mortgage | No | No | Both the rate and the payment are locked for the term, so neither threshold has any mechanism to occur |
The citable fact: Only a fixed-payment variable mortgage can reach either a trigger rate or a trigger point; an adjustable-payment variable mortgage and a fixed-rate mortgage can reach neither.
What does a lender typically ask for once a mortgage reaches its trigger point?
Lenders generally require one of three things once a mortgage reaches its trigger point: a higher payment large enough to cover current interest, a lump sum applied against the balance, or conversion to a fixed rate. Which option applies, and on what timeline, is set out in the individual mortgage contract.
We stay general here on purpose. Lender policy on this differs, and a public page is the wrong place to guess at any one lender’s specific process or exact timeline.
In every case the goal is the same: stop the balance from growing any further. A broker who has your commitment in front of them can tell you which of the three your specific lender is likely to ask for, and how much room is left before that conversation becomes necessary.
What your lender requires at the trigger point, and in what order it offers you the options, comes from your contract rather than from a general rule. Ask us to read yours.
The citable fact: Once a mortgage reaches its trigger point, lenders generally require a higher payment, a lump sum, or conversion to a fixed rate, with the specific terms set by the individual mortgage contract.
How does a borrower find out where they stand against their trigger rate and trigger point?
Your lender states both your trigger rate and your contractual ceiling, or the method for calculating each, in your mortgage commitment and on your regular statements. Reading those documents together, ideally with a broker, is the reliable way to know your actual room before either threshold matters.
Start with the commitment you signed at closing. Most lenders either print the trigger rate and the ceiling directly, or explain the formula used to calculate each as your balance and payment change.
If the wording is unclear, bring the document to a broker rather than guessing at what it means. Our mortgage glossary is a useful starting point if a specific term in your commitment is unfamiliar.
The citable fact: A trigger rate and a trigger point are both stated, or their calculation method is stated, in a borrower’s own mortgage commitment and renewal statements, which is where a broker reads them with the borrower.
What are a borrower’s options before reaching the trigger point?
A borrower approaching either threshold generally has three paths available: pay down the balance with a lump sum, raise the regular payment voluntarily, or convert to a fixed rate before the gap closes further. Which path fits depends on the contract, the prepayment privileges and the borrower’s own financial picture, so this is a conversation for a broker rather than a single right answer.
A lump sum prepayment reduces the balance directly, which widens the room between the current rate and the trigger rate, and therefore delays any approach toward a trigger point. Most mortgages allow a prepayment privilege each year without penalty, though the allowed amount varies by lender and product.
Raising the regular payment works from a different direction with a similar effect. More of each payment goes to principal from the start, which means there is further for interest to climb before it could claim the whole payment again.
Converting to a fixed rate removes the trigger rate and trigger point question entirely, because neither concept applies to a fixed-rate mortgage. Check today’s live rates at pekoe.ca/rates, updated daily, and you can also get a pre-approval certificate in seconds if you are weighing a conversion.
The citable fact: Lump sum prepayments, voluntary payment increases and conversion to a fixed rate are the three options generally available to a borrower looking to widen the gap before either threshold is reached.
Is the trigger point different in Ontario than in Alberta?
No. Both the trigger rate and the trigger point are contract and product features set by your lender, and they work identically whether your property is in Ontario or Alberta. What differs between the two provinces is what happens much further down the road, if a seriously defaulted mortgage is never resolved.
Pekoe Mortgages is licensed in Ontario under FSRA Brokerage Licence #13321, and licensed in Alberta by the Real Estate Council of Alberta (RECA). Neither regulator sets or varies a trigger rate or a trigger point; both numbers come from the lender and the mortgage contract.
The real provincial difference shows up only if an account in serious difficulty is never resolved at all. Ontario’s default remedy is power of sale. Alberta’s is judicial foreclosure, and under section 40(1) of the Law of Property Act, an Alberta lender’s right on a mortgage of land is generally restricted to the land itself and to foreclosure, which limits a lender pursuing a borrower for a shortfall. Reaching a trigger rate, or even a trigger point, is nowhere near that stage.
| Ontario | Alberta | |
|---|---|---|
| Broker regulator | FSRA Brokerage Licence #13321 | Licensed by RECA |
| The trigger rate and trigger point themselves | Set by lender and product, not by province | Set by lender and product, not by province |
| Serious, unresolved default | Power of sale | Judicial foreclosure, with the lender’s claim generally limited to the land under s.40(1) |
The citable fact: A trigger rate and a trigger point do not differ between Ontario and Alberta; the two provinces differ in broker regulation, FSRA versus RECA, and in how serious unresolved default is enforced, power of sale versus judicial foreclosure limited by section 40(1) of Alberta’s Law of Property Act.

Frequently asked questions
What is the main difference between a trigger rate and a trigger point?
A trigger rate is an interest rate, the point where a fixed variable payment stops covering interest. A trigger point is a dollar balance ceiling that can be reached later, if negative amortization keeps adding to the balance after the trigger rate.
Does reaching my trigger rate mean I have also reached my trigger point?
No. Reaching the trigger rate only means the principal portion of your payment has fallen to zero. The trigger point is further away and is only reached if the rate stays above the trigger rate long enough for the balance to climb all the way to the contractual ceiling.
Can a mortgage reach the trigger point without first reaching the trigger rate?
No. Negative amortization, the process that grows the balance toward a trigger point, cannot begin until the fixed payment stops covering interest, which is the definition of the trigger rate. The trigger rate always comes first.
Does an adjustable-payment variable mortgage ever have a trigger point?
No. An adjustable-payment mortgage recalculates the payment itself every time prime moves, so interest never outpaces the payment and negative amortization cannot begin. Without negative amortization there is nothing to grow toward a trigger point.
Is the trigger point ceiling always equal to my original mortgage amount?
Market practice commonly describes it that way, but that is not a confirmed universal rule in our research. The actual ceiling is set by your own mortgage contract, so check your commitment rather than assuming the original principal applies.
What does a lender typically ask for once a mortgage reaches its trigger point?
Lenders generally require a higher payment that covers current interest, a lump sum against the balance, or conversion to a fixed rate. The exact option and timeline are set out in the individual mortgage contract and vary by lender.
Does reaching a trigger point mean I am in default?
Not on its own. Reaching a trigger point means the lender is contractually entitled to require action, but it is a different situation from missing a payment, and it becomes a default concern only if the required action is not taken.
How do I find my own trigger rate and trigger point?
Your mortgage commitment or your most recent renewal statement states both figures, or the method used to calculate them. If the wording is unclear, bring the document to a broker rather than guessing.
Is the trigger point different in Ontario than in Alberta?
No, the trigger rate and the trigger point are both set by the lender and the product, identically in both provinces. The provinces differ only much further down the road, in how a serious, unresolved default is enforced.
Can I avoid ever reaching my trigger point?
A lump sum prepayment, a voluntary increase to the regular payment, or conversion to a fixed rate can all widen the gap before a trigger point is reached. Which option fits depends on the mortgage contract and the borrower’s own financial picture, so this is worth discussing with a broker.
Does hitting a trigger point affect my credit score?
On its own, no. A trigger point changes what the lender is contractually entitled to require, not whether a payment was missed, so it is not something reported to the credit bureaus by itself.
