What this means for your plan

Plain-English trade-offs to help you decide with confidence.

  • Long-term vs. short-term

    A 30-year loan keeps payments low but costs far more in interest. A 15-year loan flips that trade-off — higher monthly payment, much less interest.

  • Rate-sensitive plan

    At this rate, prepayments and refinances have outsized impact. Revisit your refinance plan if rates drop even half a point.

  • Money freed up = money invested

    Every dollar you save here can be redirected into long-term investing. The earlier you reroute it, the larger the compounded result.
