Description
Apply the supplied refund only in [lower,upper); subtract admin fee and clamp net at zero, otherwise return zero.
Education payment records distinguish subsidies, deposits, transferable credit, refund bands and administrative fees. A supplied calculation can reconcile a proposed balance without determining which fees or refunds are legally or institutionally available. Endpoint inclusion and the order of deductions can change the result.
Apply the supplied refund only in [lower,upper); subtract admin fee and clamp net at zero, otherwise return zero.
When to use this tool
Use Course Withdrawal Refund Caller Band when checking the stated caller-defined course-cost or refund convention.
How to use the tool and how it works
- Enter tuition, completedFraction, lowerFraction, upperFraction, refundFraction, administrativeFee. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inBand, grossRefund, netRefund. Inspect inBand before interpreting the associated values.
Require nonnegative tuition/admin fee, 0<=lower<upper<=1 and completion/refund fractions in [0,1]. Apply the supplied refund only in [lower,upper); subtract admin fee and clamp net at zero, otherwise return zero.1

}Limitations and assumptions
- This is one half-open caller band; completion=1 is outside a band ending at one. No legal or institutional refund right is determined.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect the applicable enrollment/funding agreement and current institutional rules with the responsible financial/legal professionals for actual entitlements.
