Results Explained
After calculation, you'll receive several important loan figures.
Monthly Payment
This is the amount you'll pay every month until the loan is fully repaid.
The payment includes:
- Principal repayment
- Interest charges
Total Interest
This is the total amount paid to the lender in addition to the money you borrowed.
For example:
Loan Amount:
$20,000
Total Payment:
$23,500
Total Interest:
$3,500
Total Payment
This represents the entire amount you'll repay over the life of the loan.
Formula:
Total Payment = Monthly Payment × Number of Payments
Number of Payments
This is simply the total number of monthly installments.
Examples:
- 3-year loan = 36 payments
- 5-year loan = 60 payments
- 7-year loan = 84 payments
Loan Amount
The calculator also displays the original amount borrowed for easy reference.
Loan Payment Formula
Most installment loans use an amortization formula to calculate equal monthly payments.
The formula is:
Monthly Payment = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1]
Where:
- P = Loan amount
- r = Monthly interest rate (Annual Rate ÷ 12 ÷ 100)
- n = Total number of monthly payments
If the interest rate is 0%, the calculation becomes much simpler:
Monthly Payment = Loan Amount ÷ Number of Payments
This ensures accurate repayment estimates regardless of whether interest is charged.
Example Calculation
Suppose you borrow:
- Loan Amount: $20,000
- Interest Rate: 6% annually
- Loan Term: 5 years
Monthly interest rate:
6% ÷ 12 = 0.5%
Number of payments:
5 × 12 = 60
Estimated results:
- Monthly Payment: Approximately $386.66
- Total Payment: Approximately $23,199.60
- Total Interest: Approximately $3,199.60
These values may vary slightly depending on lender policies and payment schedules.
Example with Different Loan Terms
Let's compare several repayment periods for the same $20,000 loan at a 6% annual interest rate.
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 3 Years | Higher | Lower |
| 5 Years | Moderate | Moderate |
| 7 Years | Lower | Higher |
| 10 Years | Lowest | Highest |
A shorter loan term increases monthly payments but reduces total interest.
A longer loan term lowers monthly payments but increases the total borrowing cost.
Factors That Affect Your Monthly Payment
Several factors determine how much you'll pay each month.
1. Loan Amount
Borrowing more money increases monthly payments and total interest.
2. Interest Rate
Higher interest rates result in:
- Higher monthly payments
- More total interest
- Greater overall repayment
Even a small increase in the interest rate can significantly impact the total cost over several years.
3. Loan Term
Longer loan terms reduce monthly payments but increase interest costs.
Shorter loan terms require higher monthly payments while saving money on interest.
4. Zero-Interest Loans
Some promotional financing offers 0% interest.
In this case:
Monthly Payment = Loan Amount ÷ Number of Months
This results in paying only the principal without additional interest.

Common purposes include:
- Vehicle purchases
- Home renovations
- Debt consolidation
