    How this calculation works

    According to standard financial formulas, your monthly loan payment is calculated using the same amortization formula as mortgages. The total interest paid over the life of the loan is the difference between total payments made and the original principal.

    M = P[r(1+r)^n] / [(1+r)^n-1] | Total Interest = (M × n) - P

    How interest rate affects your payment

    RateMonthly P&I ($380k, 30yr)Total Interest Paid

    6.0%$2,279$440,000
    6.41%$2,374$474,000
    6.82%$2,478$512,000
    7.5%$2,657$576,000

    A 1% rate difference on a $380,000 mortgage costs approximately $60,000 more over 30 years.

    How to Use This Calculator

    Enter the amount you want to borrow, then set an APR that reflects typical offers in Arizona (about 15.2% in our 2026 embedded dataset). Choose a term and compare monthly payment versus total interest before you commit.

    How Loan Calculator Is Calculated

    Loan payments are calculated using amortization, where interest is charged on the remaining balance and your payment is split between interest and principal. Formula: `Monthly Payment = P[r(1+r)^n] / [(1+r)^n - 1]`

    Monthly Payment = P[r(1+r)^n] / [(1+r)^n - 1]

    Using This Calculator in Arizona

    In Arizona, the cost-of-living index is 105 and median home price is about $420,000. Average household income in our dataset is $84,700—use your real take-home pay, not averages, to judge affordability.

    Tips & What Your Results Mean

    If total interest feels high, try a shorter term first. If the monthly payment is tight, reduce the loan amount and re-run—sometimes borrowing less beats stretching the term.
