    Estimates are for illustration only and assume a fixed-rate, fully-amortizing loan. Actual APR, fees, and payments depend on your lender, credit profile, and state. Kreditify is a loan comparison service, not a lender.

    How this calculator works

    The formula behind the number

    We use the standard amortization formula M = P × r / (1 − (1 + r)^−n), where P is the loan amount, r is your monthly rate (APR ÷ 12) and n is the number of monthly payments. A $300,000 mortgage at 6.75% APR over 360 months works out to roughly $1,946 per month.

    What APR includes

    APR bundles the interest rate with most lender fees, so it is the fairest number to compare offers with. Mortgage APRs on Kreditify typically fall between 3% and 12%, driven mainly by your credit profile, income stability, and the term you pick.

    Why term length matters more than you think

    Stretching the term lowers the monthly payment but raises the total interest, because you owe the balance for longer. Run the same amount at 120 and 360 months to see both sides of that trade before you commit.

    What this estimate does not include

    Origination fees deducted at funding, late fees, insurance add-ons, escrow, and taxes are excluded. Treat the result as a planning estimate, then confirm the exact figures on your lender's disclosure before signing.
