A 300k mortgage calculator is a financial planning tool tailored for one of the most common loan amounts in the US housing market.

For instance, on a $300,000 loan, the difference between a 6% and a 7% interest rate is roughly $200 per month, which adds up to over $70,000 over the life of a 30-year loan.
