To calculate the impact of extra payments on a loan in Excel, use the formula `=PMT(interest_rate/periods, total_number_of_payments, -loan_amount) + extra_payment`. Replace `interest_rate`, `periods`, `total_number_of_payments`, `loan_amount`, and `extra_payment` with your specific values. This formula recalculates the monthly payment inclusive of any additional payments, helping you understand how they reduce the loan term and interest paid over time.
