Loan Amount: $${loanAmount.toFixed(2)}

Formulas:
Monthly Payment = (Loan Amount × Interest Rate) / (1 – (1 + Interest Rate)^-Loan Term)
Total Repayment = Monthly Payment × Loan Term

Results:
Monthly Payment: $${monthlyPayment.toFixed(2)}
Total Repayment: $${totalRepayment.toFixed(2)} `; document.getElementById(“calculationSteps”).innerHTML = steps; } function resetAutoLoan() { document.querySelectorAll(“.calculator-form input”).forEach(input => input.value = “”); document.getElementById(“calculationSteps”).innerHTML = “
