Quick Answer
To calculate your monthly payment, use the formula: Payment = Principal × [Rate × (1 + Rate)^Months] / [(1 + Rate)^Months - 1]. Our free payment calculator at practicalwebtools.com does this instantly - just enter your loan amount, interest rate, and term to see your exact monthly payment.
Key Facts
- Monthly payment formula uses loan amount, interest rate, and number of payments
- Higher interest rate = higher monthly payment for the same loan amount
- Longer loan term = lower monthly payment but more total interest
- The first few payments are mostly interest, shifting to principal over time
- A payment calculator helps you budget before committing to a loan
- Bi-weekly payments (every 2 weeks) result in 13 annual payments instead of 12
Frequently Asked Questions
Monthly payment uses the amortization formula: M = P × [r(1+r)^n] / [(1+r)^n-1], where M=monthly payment, P=principal, r=monthly interest rate (annual/12), n=number of payments. This ensures equal payments that cover both interest and principal over the loan term.
Interest rate and term length have the biggest impact. A 1% rate increase on $200k over 30 years adds ~$120/month. Extending from 15 to 30 years cuts payment by ~40% but more than doubles total interest. Loan amount directly scales the payment.
Shorter terms mean higher monthly payments but lower total interest. A 15-year mortgage at 6% on $200k costs $1,688/month with $104k interest. A 30-year costs $1,199/month but $232k interest. Choose based on monthly budget and long-term savings goals.
Most lenders use the 28/36 rule: housing costs under 28% of gross income, total debt under 36%. If you earn $6,000/month, aim for payments under $1,680. Also factor in taxes, insurance, and maintenance costs not included in the loan payment.
Amortization spreads loan repayment over time with fixed payments. Early payments are mostly interest; later payments are mostly principal. On a 30-year mortgage, you don't reach 50% principal paid until year 20. Extra payments accelerate this timeline.
