Union Bank credit cards offer competitive interest rates and rewards. Use this calculator to estimate your monthly payments, total interest, and savings if you pay off your balance early. Enter your credit card balance, interest rate, and repayment terms to get personalized results.
How to Use This Calculator
To calculate your Union Bank credit card payments:
- Enter your current credit card balance in the "Current Balance" field.
- Input your credit card's annual percentage rate (APR) in the "Interest Rate" field.
- Select your repayment term in months from the dropdown menu.
- Click "Calculate" to see your monthly payment, total interest, and savings if you pay off early.
- Review the payment schedule chart to track your progress.
The calculator uses the standard amortization formula to compute your monthly payments. It assumes regular monthly payments and does not account for variable interest rates or additional fees.
Formula Used
The monthly payment (P) for a credit card is calculated using the formula:
P = B × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- B = Current credit card balance
- r = Monthly interest rate (APR/12/100)
- n = Number of payments (term in months)
Total interest paid is calculated by multiplying the monthly payment by the number of payments and subtracting the original balance.
Worked Example
Let's calculate the monthly payment for a $5,000 credit card balance with a 15% APR over 24 months:
- Convert the APR to a monthly rate: 15% ÷ 12 = 1.25% or 0.0125
- Plug the values into the formula:
P = 5000 × (0.0125(1 + 0.0125)^24) / ((1 + 0.0125)^24 - 1)
- Calculate the monthly payment: $243.28
- Total interest paid: $1,120.64
If you pay off the balance in 12 months instead of 24, you'll save $600 in interest.
