Estimate how much faster you can pay off the mortgage.
Start from the current balance and payment, then see how extra monthly payments change the payoff timeline and lifetime interest.
See how fast extra payments eat into the loan
This page starts from an existing balance and payment rather than a purchase price. It is for the phase where someone already has a mortgage and wants to know whether throwing extra cash at it is actually worth it.
- How many months early you could kill the mortgage.
- Whether a modest recurring extra payment materially changes lifetime interest.
- How quickly the remaining balance starts to bend downward.
This is the “what if I pay extra?” page
Affordability is about shopping, mortgage is about budgeting, amortization is about loan shape, and payoff is about strategy. This page is the closest thing to a decision tool for people already in the mortgage.
This is the most action-oriented tool in the cluster for current homeowners.
Use the schedule page if you want the broader month-by-month picture.
That’s the right tool if you don’t have the loan yet.
