Not financial advice. The chart assumes your lender allows unlimited overpayments and that the rate schedule you entered applies for the full term. The "invest instead" figure uses a fixed annual return assumption; real returns will vary. Your inputs stay in your browser.
What if that overpayment grew as dividend income?
If you invested your overpayment at 6.00% dividend growth, DividendMapper models the actual income your portfolio could produce. It is worth comparing that against the guaranteed interest saving from overpaying.
