How To Build Your Own Credit Card Repayment Calculator

We’ve all been there – a new month begins and it’s time to pay off bills. However, all bills are not equal – some are minor inconveniences while others have you begging for sweet release. Your credit card bill falls under the second category. While we may not be able to help you pay off your bills, we can definitely help you create a credit card repayment calculator to determine the number of days until the sweet release.

Outgrow allows you to build a wide range of calculators with complex formulas and logical statements. Here we’ll go through the steps involved in creating a credit card debt calculator.

The Credit Card Equation calculator computes the amount of time required to pay off a credit card debt, or other fixed-rate loans, based on the (APR), total balance (b), and the monthly payment (p), where

  • (APR) is the annual percentage rate of interest
  • (b)  is the balance of the credit card debt
  • (p)  is the monthly payment to be made

Here, we’ll walk through creating a credit card debt calculator, a timely tool considering the average American’s credit card debt rose to $5,910 (nearly $6,000) in 2022, according to Experian. This calculator will help you understand how long it might take to pay off your own credit card debt, given the interest rate, balance, and monthly payment amount.

The formula in play here is –

M = P(1+r)n r / [(1+r)n-1]

N= −1/30⋅ln(1+bp⋅(1−(1+APR365)30))/ln(1+APR365)

Step-by-Step Process to Create Credit Card Repayment Calculator

For starters, you’ll need the following inputs from the users

Q1. Your credit card balance
Q2. Credit card interest rate
Q3. Payment amount per month

2. Once you’re done with the questions, it’s time to define the input methods for each question in the calculator. You can choose between text inputs, drop-down, multi-select, single select, opinion scale, rating, and numeric slider.

Note: If you are using a numerical slider, do not forget to mention the upper and lower limits along with the step-length.

3. Now, it’s time to add the formula to the mix to accomplish the goal of creating this calculator.

The formula for calculator the time to pay off credit card debt is – (log((1-((Q2/1200)*Q1/Q3)),10))/(log(1+(Q2/1200),10))

You can copy and paste this to the formula builder. See it in action in the screenshot below.

Here, we have divided Q2 by hundred because we are capturing these inputs in % form

In the formula builder:-

    • Add prefix and suffix as required. In this example, we have added ‘$’ as a prefix
    • You can also add decimal places if required
    • You can quickly validate the formula if the sample result displayed is correct.

Note: You can also use JSON to import formulae into the builder

The Next Steps

Once you are done setting up the formula, you can focus on lead generation. This is the most important part in the whole process. Did you know – the use of an interactive calculator has helped Venturepact generate 12x more leads? Thus, it makes sense to focus more on adding the lead gen form. Place the lead gen form just before the results. Similarly, incorporating insights from a payments consulting firm can optimize the use of such calculative tools for better financial management and lead conversion.
