Loan Calculator - Monthly Payment & Amortization

Before taking on any loan, you need to know exactly what it will cost. The BulkCreator Loan Calculator computes your monthly payment, total interest paid, and total cost of the loan based on three inputs: loan amount, interest rate, and term length. It works for mortgages, auto loans, personal loans, student loans, and any fixed-rate installment loan.

The tool generates a complete amortization schedule showing how each monthly payment splits between principal and interest over the life of the loan. Early payments are mostly interest; later payments are mostly principal. This visualization helps you understand the true cost of borrowing and evaluate strategies like extra payments or refinancing.

Adjusting the inputs in real time lets you explore scenarios: How much does a 0.5% rate reduction save? What if you shorten the term from 30 to 15 years? What happens if you add $200/month in extra principal payments?

The tool uses the standard amortization formula:

M = P * [r(1+r)^n] / [(1+r)^n - 1]

Where:
  M = Monthly payment
  P = Principal (loan amount)
  r = Monthly interest rate (annual rate / 12)
  n = Total number of payments (years * 12)

Example: A $300,000 loan at 6.5% for 30 years = $1,896.20/month. Total interest paid: $382,633.
