$30,000 @ 6.5% × 60 moMonthly $587 · Total interest $5,200$50,000 @ 5% × 10 yrMonthly $530 · Total interest $13,640Frequently asked questions
How is the monthly payment calculated?
Standard amortization: P × r / (1 − (1+r)^−n), where P is principal, r is monthly rate, n is total payments.
Why is most of my early payment going to interest?
Interest is computed on the remaining balance each month. Early on, balance is high so interest is high. As you pay down principal, more of each payment goes to principal.
Should I refinance?
Generally worth it if a new rate is at least 0.5-1% lower AND you plan to keep the loan long enough to recoup closing costs. Use our Refinance Calculator to model.
