Understanding Your Payment
Your $200,000 loan payment is calculated using the standard amortization formula. At 5% interest over 15 years, you'll make 152 monthly payments of $1,581.59 plus your extra $200 payment.
Payment breakdown: Each month, your payment is divided between principal (reducing your balance) and interest (the cost of borrowing). Initially, 46.8% goes to interest. Over time, more goes toward principal as your balance decreases.
Rate sensitivity: At 5%, your first-month interest charge is $833.33. Even small rate changes significantly impact your total interest paid — see the rate comparison below.
Extra payment impact: Your $200 extra monthly payment goes entirely toward principal, reducing your balance faster and saving $14,475.52 over the loan term.
