Description
Prorate fee by unused/year days.
Financial accounting arithmetic tracks amounts, balances, fees and allocations on a declared currency and sign basis. An algebraically consistent result does not authorize a transaction or establish an amount legally due.
Prorate fee by unused/year days.

}Limitations and assumptions
- The day basis and refund policy are supplied. This calculation does not determine cancellation rights, refund eligibility or actual reimbursement.
- 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
Reconcile source ledgers and governing agreements using the intended currency precision and accounting policy. Include omitted fees, tax, timing and legal requirements before acting on a result.
