Minimum Payment Calculator
Minimum Payment is evaluated from Current Balance, Annual Percentage Rate and Minimum Payment% of Balance. The calculation reports Months to Pay Off, Total Interest and Months to Pay Off.

About the Minimum Payment Calculator
The calculator uses a custom php logic configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
Minimum Payment each month = max(Balance x min_pct%, floor_amount)
1. Calculate monthly interest: Balance x APR / 1200
3. New balance = Old balance + interest - payment
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: Minimum Payment each month = max(Balance x min_pct%, floor_amount) 1. Calculate monthly interest: Balance x APR / 1200 3. New balance = Old balance + interest - payment Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Typical Credit Card Balance
Inputs
With Current Balance = 5,000, Annual Percentage Rate = 22.99, Minimum Payment% of Balance = 2 and Minimum Payment Floor = 25 as the stated inputs, the result is Months to Pay Off = 600 months, Total Interest = $45,140 and Months to Pay Off = 600 months. Each value corresponds to the declared output fields.
Example 2: High-Balance Scenario
Inputs
With Current Balance = 12,000, Annual Percentage Rate = 24.99, Minimum Payment% of Balance = 2 and Minimum Payment Floor = 35 as the stated inputs, the result is Months to Pay Off = 600 months, Total Interest = $193,911 and Months to Pay Off = 600 months. Each value corresponds to the declared output fields.
Example 3: Low Balance — Still Costly
Inputs
With Current Balance = 1,500, Annual Percentage Rate = 26.99, Minimum Payment% of Balance = 2.5 and Minimum Payment Floor = 25 as the stated inputs, the result is Months to Pay Off = 265 months, Total Interest = $6,068 and Months to Pay Off = 265 months. Each value corresponds to the declared output fields.
Example 4: Floor Payment Dominates
Inputs
With Current Balance = 800, Annual Percentage Rate = 21.99, Minimum Payment% of Balance = 2 and Minimum Payment Floor = 25 as the stated inputs, the result is Months to Pay Off = 49 months, Total Interest = $416 and Months to Pay Off = 49 months. Each value corresponds to the declared output fields.
Common Use Cases
