tool.loan-extra-payment Calculator
Calculates how many months an extra monthly payment reduces a loan term and the total interest saved over the life of the loan. An extra $100/month on a $200k, 30-year mortgage saves tens of thousands in interest and cuts years off the term.
Inputs
Balance
Reference formula or conversion factor shown for context.
Rate
Yearly rate as a percentage. The calculator converts this to the appropriate period rate automatically.
Current Pmt
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Extra Pmt
Reference formula or conversion factor shown for context.
Results

The result expressed in months. Divide by 12 to convert to years.
payoff with extra (months)
The result expressed in months. Divide by 12 to convert to years.
months saved

years saved
The total amount saved compared to the baseline scenario — cost savings, time savings, or resource savings.
interest saved ($)
The total amount saved compared to the baseline scenario — cost savings, time savings, or resource savings.
