About the APR to Daily Periodic Rate Calculator
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
Daily Periodic Rate = APR / 365
Monthly Rate = APR / 12
Effective Annual Rate = (1 + DPR)^365 - 1
(Accounts for daily compounding - the true annual cost)
Daily Cost per $1,000 = $1,000 x DPR
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: Daily Periodic Rate = APR / 365 Monthly Rate = APR / 12 Effective Annual Rate = (1 + DPR)^365 - 1 (Accounts for daily compounding - the true annual cost) Daily Cost per $1,000 = $1,000 x DPR 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: Average US Credit Card Rate
Inputs
With Credit Card APR = 22.99 as the stated inputs, the result is Daily Periodic Rate = 0.06299%, DPR = 0.0006299 decimal and Monthly Rate = 1.9158%. Each value corresponds to the declared output fields.
Example 2: Retail/Store Card — High Rate
Inputs
With Credit Card APR = 29.99 as the stated inputs, the result is Daily Periodic Rate = 0.08216%, DPR = 0.0008216 decimal and Monthly Rate = 2.4992%. Each value corresponds to the declared output fields.
Example 3: Low-Rate Credit Union Card
Inputs
With Credit Card APR = 12.5 as the stated inputs, the result is Daily Periodic Rate = 0.03425%, DPR = 0.0003425 decimal and Monthly Rate = 1.0417%. Each value corresponds to the declared output fields.
Example 4: Minimum Rate — Reward Card Excellent Credit
Inputs
With Credit Card APR = 15.99 as the stated inputs, the result is Daily Periodic Rate = 0.04381%, DPR = 0.0004381 decimal and Monthly Rate = 1.3325%. Each value corresponds to the declared output fields.
