How Monthly Payments are Calculated
Most modern loans use a fixed-rate amortization schedule. This means that while your monthly payment stays the same, the proportion of that payment going toward the interest decreases over time as your principal balance drops.
The Standard Payment Formula:
M = P × r(1 + r)n / ((1 + r)n − 1)
- M: Total monthly payment.
- P: Principal loan amount.
- r: Monthly interest rate (Annual rate divided by 12).
- n: Number of months (Term length).
Why Use This Calculator?
Using a generic payment calculator on familyhealthcalc.com allows you to plan for life’s “hidden” costs:
- Consumer Financing: Calculate payments for store-credit purchases (0% interest periods vs. high-interest standard rates).
- Private Loans: If you are borrowing from or lending to a family member, use this tool to create a fair and professional repayment schedule.
- Student Loans: Estimate the monthly impact of fixed-rate education loans in the US and UK.
- Debt Comparison: Compare two different loan offers to see which one costs less in total interest, regardless of the monthly payment size.
