Owned Outright

US mortgage payoff maths from ownedoutright.com. Give ChatGPT your balance, rate and time left. It works out the new payoff date and the interest saved from a monthly, yearly or one-time extra payment, the extra needed to be mortgage-free by a date, or how many months until a refinance pays for its closing costs. Every answer links to the matching calculator so you can adjust the numbers. Education only, not financial advice.
