    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
    5.5%$2,158$397,000
    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

    Set your loan amount, then try an APR around Texas’s typical personal-loan pricing (about 15.8% in our dataset). Pick a term and compare monthly payment vs total interest—Texas’ no-income-tax status doesn’t make high interest “free.”

    How Loan Calculator Is Calculated

    Amortization uses a fixed payment where interest is calculated on the remaining balance. 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 Texas

    Texas has 0% state income tax, which can increase take-home pay compared with taxed states. Still, with an average APR around 15.8%, a longer term can quietly add thousands in interest—use the calculator to see the true cost.

    Tips & What Your Results Mean

    If you’re using a loan for debt consolidation, compare the APR to your credit card rate and confirm the new payment is sustainable. Don’t optimize only for monthly payment—optimize for payoff speed and interest saved.
