Reading an amortization schedule
Every fixed payment splits into interest (the balance times the monthly rate) and principal (the rest). The split shifts steadily: on a 30-year loan at 6.5%, the first payment is roughly three-quarters interest, while the last is nearly all principal. The crossover — where payments become majority-principal — often arrives past the loan's halfway point.
Why this table matters
The schedule shows exactly how much equity each year builds and what refinancing or extra payments would work against. Lenders publish the same table at closing; running your own numbers first means no surprises at the table.
