What the calculation assumes
The rate and frequency you entered apply for the whole period shown. In real life, the rate changes at every renewal.
Three numbers to read together
Read the three numbers together: the payment, the total paid, and the interest. Stretching the amortization lowers the monthly payment, but you pay more interest overall.
What it does not tell you
This is not a quoted rate or an approval. Insurance, taxes, and property costs are not in it either.
Next step
Send me the balance, rate, and amortization you entered: I’ll tell you what the payment becomes with taxes, insurance, and the rate a lender would offer you today.
