How It Works
Enter your loan amount, initial rate (%), adjusted rate (%), initial period (years), loan term (years), and the calculator instantly computes your initial monthly payment, adjusted payment, payment increase, total interest. For example, with Loan Amount: $350,000, Initial Rate (%): 5.5%, Adjusted Rate (%): 7.5%, Initial Period (Years): 7, Loan Term (Years): 30, the initial monthly payment comes out to $1,987.

Practical Tips
- →Shop multiple lenders — even a small rate difference saves real money over the loan term
- →Always compare the APR, not just the headline interest rate
- →Extra payments toward principal shorten your payoff time and cut total interest
- →Avoid extending loan terms just to lower the monthly payment — it usually costs more overall
