Step-By-Step Guide to Calculate Student Loan Payments
Student loan calculation is not a random process. It has a specific calculation formula. Using the loan amount, interest rate, and duration, you can calculate the monthly payment.
You can also use online tools, such as a student loan payment calculator. It helps to calculate the amount quickly. But it is helpful to understand these steps.
Here’s a step-by-step overview of the calculation process:
- Step 1: Divide your annual interest rate by 12 to calculate your monthly interest rate.
- Step 2: Calculate the total number of EMIs by multiplying the total repayment years by 12.
- Step 3: Use the loan repayment formula to calculate the fixed monthly amount.
- Step 4: Divide your EMIs into interest and principal. It will give you a better understanding of the monthly payments.
Here is the formula to calculate your monthly payments:
EMI = (P × r × (1 + r)n) ÷ ((1 + r)n − 1)
Here:
- EMI = monthly payment amount.
- P = Principal or loan amount.
- r = Monthly interest rate (annual interest rate ÷ 12).
- n = total number of monthly payments.
This formula is used in most student loan monthly payment calculators. So, you can use it to avoid manual effort.
Here’s an example to simply explain the calculation:
- The total loan amount is R100,000
- The annual interest rate is 9% per year.
- Repayment term = 5 years = 5 x 12 = 60 months.
First, convert the annual interest rate to monthly: 9 ÷ 12 = 0.75%
Convert the 0.75% into a decimal for the formula: 0.75/100 = 0.0075.
If you enter the values into the EMI formula, you get approximately R2,075.84 per month.
It might be confusing for some individuals. You can also use the EMI or student loan interest rate calculators.
