1. What is the Tesco Credit Card Repayment Formula?

The Tesco Credit Card Repayment Formula calculates how long it will take to pay off a credit card balance based on your monthly payment amount and interest rate. It accounts for the compounding effect of interest on your remaining balance.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ T = \frac{\log\left(\frac{P}{P - D \times R}\right)}{\log(1 + R)} \]

Where:

\( P \) — Principal balance (GBP)
\( D \) — Monthly payment (GBP)
\( R \) — Monthly interest rate (annual rate / 12, as a decimal)
\( T \) — Time to repay (months)

Explanation: The formula calculates how many months it will take to pay off the balance by accounting for the decreasing principal and compounding interest each month.

3. Importance of Repayment Calculation

Details: Understanding your repayment timeline helps with financial planning, avoiding excessive interest payments, and making informed decisions about payment amounts.

4. Using the Calculator

Tips: Enter your current balance, monthly payment amount, and annual interest rate. All values must be positive numbers. Note that your payment must exceed the monthly interest charge to eventually pay off the debt.

5. Frequently Asked Questions (FAQ)

Q1: What if my payment is too low to pay off the debt?
A: The calculator will show "∞" if your payment is less than or equal to the monthly interest charge, meaning you'll never pay off the balance.

Q2: Does this account for minimum payments?
A: No, this calculates based on fixed monthly payments. Minimum payments typically extend repayment time significantly.

Q3: How accurate is this calculation?
A: It's mathematically precise for fixed payments and interest rates, but doesn't account for changes in rates, fees, or payment amounts.

Q4: What's the best way to pay off credit card debt faster?
A: Increase monthly payments, pay more than the minimum, or consider balance transfers to lower-interest cards.

Q5: Does Tesco offer any repayment tools?
A: Tesco Bank may offer online calculators or repayment tools through their online banking portal.
