What the defaults give

$200,000 at 6.5% over 30 years has a payment of $1,264.14 a month.

Over 360 payments that is $455,089, so interest is $255,089 — more than the amount borrowed. In the first month only $180.80 reduces the balance.

The formula

Payment = P × i ÷ (1 − (1 + i)^−n)

P is the loan, i the monthly rate (annual ÷ 12 ÷ 100) and n the number of payments. For the default, i = 0.0054167 and n = 360, giving a factor of 0.0063207 per dollar borrowed.

How the split shifts

Interest each month is the outstanding balance × i. Month one: 200,000 × 0.0054167 = $1,083.33, leaving $180.80 of the $1,264.14 to reduce the principal. The next month charges interest on $199,819.20, so slightly less goes to interest and slightly more to principal. The payment stays fixed; only the split moves.

Worked comparisons

$200,000, 6.5%, 30 years → $1,264.14, $255,089 interest
$100,000 → $632.07, $127,544 interest
$400,000 → $2,528.27, $510,178 interest
3.25% instead of 6.5% → $870.41, $113,349 interest
13% instead of 6.5% → $2,212.40, $596,464 interest
15 years instead of 30 → $1,742.21, $113,599 interest
60 years instead of 30 → $1,105.96, $596,289 interest

Two results stand out. Halving the rate cuts the payment by a third and the interest by more than half. Halving the term raises the payment by 38% and saves $141,490 of interest — the single largest lever available without changing the loan. Doubling the term to 60 years lowers the payment by only $158 a month while adding $341,200 of interest; it is a cash-flow tool, not a saving.

Reading a schedule

The crossover — the month where principal finally exceeds interest — comes late. At 6.5% over 30 years it arrives around month 262, past the 21-year mark. Until then the bank is being paid more each month than the balance is shrinking.

Extra payments change the shape dramatically because they go entirely to principal. An extra $200 a month from the start on this loan clears it roughly seven years early and saves about $63,000 of interest, since every dollar removed now also removes all its future interest.

Escrow is not in the payment. Property tax and insurance are collected alongside it in most US mortgages, so the amount debited is higher than the figure here. Quote the principal-and-interest number when comparing loans, and the full escrow figure when budgeting.

Frequently Asked Questions

What is the monthly payment on a $200,000 mortgage at 6.5%?

$1,264.14 for 30 years. That is principal and interest only; tax and insurance would be added on top.

How much interest do I pay in total?

$255,089 over 30 years at 6.5% — more than the $200,000 borrowed, because the balance falls slowly for the first two decades.

Why is so little principal paid at the start?

Interest is charged on the full balance, so at 6.5% the first month costs $1,083.33 of interest and only $180.80 of principal.

How much does a shorter term save?

A 15-year term at the same rate raises the payment to $1,742.21 but cuts total interest from $255,089 to $113,599.

Do extra payments help?

Yes, because they reduce principal directly. $200 extra a month from the start shortens this loan by roughly seven years.
