1. What is the Extra Payment Calculator?

The Extra Payment Calculator estimates how quickly you can pay off your credit card debt by making additional payments beyond your minimum monthly payment. It shows the power of extra payments in reducing both your payoff time and total interest paid.

2. How Does the Calculator Work?

The calculator uses the following formula:

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

Where:

$ P $ — Principal balance ($)
$ E $ — Extra payment amount ($)
$ D $ — Monthly payment amount ($)
$ R $ — Monthly interest rate (APR/12 as decimal)
$ T $ — Time to payoff (months)

Explanation: The formula calculates how many months it will take to pay off your credit card debt when making regular payments plus any extra amount you can afford.

3. Importance of Extra Payments

Details: Making extra payments can significantly reduce the time it takes to become debt-free and decrease the total interest you'll pay. Even small additional amounts can make a big difference over time.

4. Using the Calculator

Tips: Enter your current credit card balance, your minimum monthly payment, any extra amount you can pay each month, and your card's APR. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate assuming fixed interest rates and consistent payments. Actual results may vary slightly if your APR changes or payments fluctuate.

Q2: Should I pay extra toward principal or interest?
A: Credit card payments always go toward interest first, then principal. Extra payments automatically reduce your principal balance faster.

Q3: What's the best strategy for paying off credit cards?
A: The "avalanche method" (paying highest APR cards first) saves the most money, while the "snowball method" (paying smallest balances first) provides psychological wins.

Q4: How much extra should I pay each month?
A: Pay as much as you can comfortably afford. Even $20-50 extra per month can shave months or years off your debt.

Q5: What if I can't make extra payments?
A: Focus on at least making the minimum payments on time to avoid penalties. Look for ways to reduce expenses or increase income to free up money for extra payments.
