Extra Payment Savings Calculator
The headline number people want is interest saved, not just months shaved. This page leads with the comparison: baseline total interest versus schedule with $250 extra per month on a $300,000 mortgage at 6.5%.
Controls below change the extra amount and show the full schedule so you can verify the maths. Copy link shares layout only — loan figures never appear in the URL.
Early extra payments save more interest than late ones because they attack principal when the balance is highest.
