Understanding your $300,000 mortgage
A $300,000 mortgage paid off in 15 years builds equity fast. You own a $300k+ asset in half the time — freeing up cash flow for investing later.
At 6.5% over 15 years, your required monthly payment is $2,613. Of that, roughly $1,625 goes to interest in the first month, while only $988 reduces your balance. Over the full term, you'll pay $170,398 in interest.
How to save on this mortgage
The interest savings between 15-year and 30-year on a $300k loan at 6.5% is over $200,000. That's money that could be invested instead.
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 $11,250 over 15 years.
