Amortization Schedule
📘 Overview: Understand Your Loan Repayment
The Loan Amortization Calculator helps you estimate your monthly loan payments and generate a detailed amortization schedule. Whether you're taking out a mortgage, personal loan, car loan, or refinancing an existing debt, this tool provides a transparent view of how your payments are split between principal and interest over time.
- 📆 Shows monthly payment amount and payment count
- 📉 Breaks down principal vs. interest per month
- 📊 Displays a full amortization schedule
- 🧮 Suitable for home loans, auto loans, student loans, and more
Use this tool to budget accurately, compare loans, or plan for early payoff.
📐 Formula & Methodology
Monthly payments are calculated using the standard loan amortization formula:
M = P x {r(1+r)^n}/{(1+r)^n - 1}Where:
- P = Loan Amount (Principal)
- r = Monthly Interest Rate = Annual Rate ÷ 12 ÷ 100
- n = Total Number of Payments = Years × 12
The amortization schedule simulates the repayment month-by-month. For each payment, it calculates:
- 💸 Interest Paid = Current Balance × Monthly Interest Rate
- 🏦 Principal Paid = Monthly Payment − Interest Paid
- 📉 Remaining Balance = Previous Balance − Principal Paid
This breakdown shows how interest costs decrease and principal repayments increase over time.
📊 Example Calculation
Suppose you take out a home loan with the following parameters:
- 🏠 Loan Amount: €200,000
- 💼 Interest Rate: 4% annually
- 📅 Loan Term: 30 years (360 months)
Monthly Interest Rate = 0.04 ÷ 12 = 0.003333
Total Payments = 30 × 12 = 360
Plug into the formula:
M = 200,000 × [0.003333 × (1 + 0.003333)^360] ÷ [(1 + 0.003333)^360 − 1]
≈ €954.83 The calculator then generates a full 30-year amortization table showing each month's interest, principal, and remaining balance.
📌 Common Use Cases

- 🚗 Planning auto loan repayment strategies
- 🎓 Estimating student loan payoff schedules
- 🔁 Evaluating refinancing opportunities
- 📈 Visualizing how early payments reduce interest
❓ Frequently Asked Questions
What is loan amortization?
Loan amortization is the process of gradually repaying a loan with equal payments over time. Each payment includes both interest and principal, with the interest portion decreasing as the loan progresses.
How is the monthly payment calculated?
The monthly payment is based on the loan amount, interest rate, and term using the amortization formula:
\( M = P \cdot \frac{r(1 + r)^n}{(1 + r)^n - 1} \)
Can I use this tool for variable rate loans?
This calculator assumes a fixed interest rate. For variable rate loans, the actual payments and interest may change over time.
Does this include extra payments?
Not yet. However, you can simulate faster payoff by shortening the loan term or increasing your monthly payment manually.
What’s the benefit of seeing an amortization schedule?
It helps you understand how much of each payment goes to interest versus principal, and how quickly you're building equity or paying down debt.
Can I export or print the amortization table?
Yes, the tool includes export and print options for record-keeping or sharing with lenders or advisors.
What if I refinance my loan?
You can enter your new loan amount, interest rate, and term to compare your new amortization schedule with the previous one.
