A loan that never reaches 80% of the price

If the schedule finishes, a normal amortizing loan does reach any balance below the start. A warning means the inputs do not produce that path.

When the message appears

The PMI note says the loan does not reach 80% of the home value when no payment on the schedule brings the balance to that target. Check that a price, a down payment, a term, and a rate are the loan you meant.

PMI also has to be in the payment. If you are at 20% down, there is no PMI date to fail. The line is simply absent.

A fully amortizing loan does get to zero

On the formula this app uses, a positive principal, a finite rate, and a positive term produce a payment that ends at zero. The 80% balance is higher than zero, so it is reached along the way whenever the schedule is that formula.

If you see the warning, treat it as a prompt to recheck the typed price and the loan, not as advice that PMI lasts forever on a standard fixed loan.

What will not create the date

A future appraisal will not. Extra payments you plan to make will not, because they are not in this schedule. The date is scheduled payments only.

FHA loans should not use this sentence at all. See the guide on FHA insurance.

This explains how WiseCalculator treats the numbers you type. It is not a lender’s offer and it is not advice for your loan.
