Frequently Asked Questions about the Amortization Calculator
What is the amortization formula?
Monthly payment P = L x (r x (1+r)^n) / ((1+r)^n - 1), where L is the loan, r is the monthly rate (annual rate / 12), and n is the number of months. Each payment splits into interest on the current balance plus principal.
Can you give a real example?
A $200,000 30-year loan at 6.5% has a base payment of about $1,264 per month. Year one, roughly $13,000 goes to interest and only $2,200 to principal. By year 25, the ratio is reversed.
What inputs matter most?
Principal, annual rate, and term drive the base payment. Extra monthly payments are powerful: an extra $200 on the example loan above shortens the term by about 6 years and saves roughly $60,000 in interest.
What is a common pitfall with amortization schedules?
People assume early payments build equity quickly. They do not. On a 30-year mortgage, you usually do not cross the 50% principal mark until past year 20 unless you make extra payments.
Does this schedule include taxes, insurance, or escrow?
No. The schedule covers principal and interest only. US lenders typically escrow property tax, homeowners insurance, and sometimes PMI on top. Use the mortgage calculator for a full PITI estimate.
