Loan amount is known as the amount you are keen to borrow. In Singapore, you are allow a maximum loan amount of 4x your monthly income. Eg. If you monthly income is $2500, your maximum available loan amount is $10,000.
Loan tenure is your preferred loan tenure in years. You are allow a maximum loan tenure of 5 years and a minimum of 1 year.
Annual Interest Rate is known as the interest rate charge to you by the financial institution. Generally, the interest rate for Personal Loan ranges from 4% to 15% per annual.
Personal Loan Calculation case study
Mr Tan monthly income is $2500 and took a $10,000 personal loan from Bank A at an interest of 4%.
He chooses repayment tenure of 5 years.
Annual Interest Rate= 4%
5 Years Interest Rate= 4% x 5 years = 20%
Total interest paid to Bank A for 5 years = Total personal loan amount x total interest for the full loan tenure = $10,000 x 20% = $2000
Total Personal loan = $10,000
Total Interest Paid = $2000
Total Tenure = 5 years = 60 months
Monthly Instalment = (Total personal loan amount + Total interest paid) / Total tenure = ($10,000 + $2000) / 60 = $200
