The BlushKey Mortgage Payoff Planner is a mortgage payoff calculator spreadsheet that shows you exactly when you’ll be mortgage-free and how much interest every extra payment saves. Enter your loan amount, interest rate, term and first payment date, and the workbook does the rest: your monthly payment, a complete amortization schedule, your new payoff date, time saved, interest saved, milestones and easy-to-read charts. Then use the built-in payment tracker to log real payments from your lender statements and see if you’re ahead of your plan.
It opens in Microsoft Excel and Google Sheets, needs no macros or sign-ups, and uses a soft blush-pink design that is calm, clear and easy to read.
Why Use a Mortgage Payoff Calculator Spreadsheet?
A mortgage is usually the biggest debt a household ever carries, and small changes make a huge difference. An extra $200 a month, a tax refund sent to principal or switching to biweekly-style payments can cut years off a 30-year loan and save tens of thousands in interest. BlushKey turns those “what ifs” into real numbers in seconds, so you can choose a plan with confidence and stay motivated as your balance falls.

- First-time buyers comparing 15-year and 30-year loans

- Beginners who want clear answers without doing any math
