Repayment Details
What Is an Amortised Loan?
An amortised loan is a type of loan where you pay a fixed amount every month over the loan term. Each payment covers both the interest and a portion of the principal, gradually reducing the outstanding balance.
Key features include:
- Fixed monthly payments
- Structured repayment schedule
- Predictable total cost over time
Amortisation ensures that by the end of the loan term, the loan is fully paid off. Mortgages, car loans, and personal loans are commonly structured this way.
How the Amortised Loan Calculator Works
The calculator applies the standard amortisation formula to compute monthly repayments:Monthly Payment=1−(1+r)−nP⋅r
Where:
- P = loan principal amount
- r = monthly interest rate (annual rate ÷ 12)
- n = total number of payments (years × 12)
If the interest rate is 0%, the formula simply divides the loan amount evenly across all months.
The calculator also computes the total payment over the loan term by multiplying the monthly payment by the total number of months.
How To Use the Amortised Loan Calculator
Using this calculator is simple and straightforward. Here’s a step-by-step guide:
Step 1: Enter the Loan Amount
Provide the total loan amount you wish to borrow. This could be:
- $10,000 for a personal loan
- $250,000 for a mortgage
- $30,000 for a car loan
Step 2: Enter the Annual Interest Rate (%)
Input the annual interest rate charged by the lender. Typical examples:
- 3–5% for home loans
- 5–12% for personal loans
- 4–8% for auto loans
Step 3: Enter the Loan Term (Years)
Specify the duration over which you will repay the loan. Common terms include:
- 1–5 years for personal loans
- 10–30 years for mortgages
- 3–7 years for car loans
Step 4: Click “Calculate”
The tool will display:
- Monthly Payment: How much you pay every month
- Total Payment: The sum of all payments over the loan term
Step 5: Reset (Optional)
Click the reset button to clear inputs and calculate a different scenario.
Example Calculation
Let’s consider a practical example:
- Loan amount: $20,000
- Annual interest rate: 5%
- Loan term: 5 years
Step 1: Compute monthly interest rate
5% ÷ 12 = 0.4167% per month
Step 2: Calculate total number of payments
5 × 12 = 60 payments
Step 3: Apply amortisation formulaMonthly Payment=1−(1+0.004167)−6020,000⋅0.004167≈377.42
Step 4: Total Payment
377.42 × 60 ≈ $22,645.20
This shows that over 5 years, you will pay $2,645.20 in interest, along with the principal.
