Understanding Your Payment
Your $250,000 loan payment is calculated using the standard amortization formula. At 6% interest over 15 years, you'll make 168 monthly payments of $2,109.64 plus your extra $100 payment.
Payment breakdown: Each month, your payment is divided between principal (reducing your balance) and interest (the cost of borrowing). Initially, 56.6% goes to interest. Over time, more goes toward principal as your balance decreases.
Rate sensitivity: At 6%, your first-month interest charge is $1,250.00. Even small rate changes significantly impact your total interest paid — see the rate comparison below.
Extra payment impact: Your $100 extra monthly payment goes entirely toward principal, reducing your balance faster and saving $10,233.82 over the loan term.
