function calculateLoan(principal, rate, term, compounding) {
    const monthlyRate = rate / 100 / 12;
    const months = term * 12;
    const monthlyPayment = principal * monthlyRate * Math.pow(1 + monthlyRate, months) /
                          (Math.pow(1 + monthlyRate, months) - 1);
    const totalPayment = monthlyPayment * months;
    const totalInterest = totalPayment - principal;

    return {
        monthlyPayment: monthlyPayment.toFixed(2),
        totalPayment: totalPayment.toFixed(2),
        totalInterest: totalInterest.toFixed(2)
    };
}
