What is a mortgage amortization schedule?
An amortization schedule shows how each monthly payment splits between principal and interest. Early payments are mostly interest; later payments chip away more principal. Searching amortization calculator or mortgage amortization table is common when borrowers want transparency.
Tools N Go displays the schedule in the browser and lets you export CSV for Excel or Google Sheets.
Using extra payments in the schedule
Even a modest extra principal payment can shave years off a 30-year loan. The calculator will recalculate the schedule when you add a monthly extra amount so you can see new payoff timing and interest saved.
