Understanding your $300,000 mortgage
A $300,000 mortgage is around the national median for new home loans. It buys a comfortable family home in most metro areas outside the coasts.
At 6.5% over 30 years, your required monthly payment is $1 896. Of that, roughly $1 625 goes to interest in the first month, while only $271 reduces your balance. Over the full term, you'll pay $382 633 in interest.
How to save on this mortgage
Adding just $200/month extra saves over $100,000 in interest and pays off the loan 5+ years early. Small amounts compound into huge savings.
What affects your actual rate
The 6.5% rate shown here is a snapshot. Your actual rate depends on your credit score (760+ gets the best rates, below 640 adds 1–2%), the loan type (conventional, FHA, VA), down payment size (20%+ avoids PMI and often gets a better rate), and market conditions. Even a 0.25% difference on a $300,000 loan saves roughly $22 500 over 30 years.
