Calculation method
Calculation method
Distance remaining (km)
max(0,allowance−actual).
Energy remaining (kWh)
max(0,allowance−actual).
Excess charge (USD)
max(0,distance−allowance)×distance rate+max(0,energy−allowance)×energy rate.

Assumptions & limits
Assumptions & limits
- Separate mileage and energy contract excess rates; the entered contract must charge both additively. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. All numeric values must be finite. Lists contain at most 100 records; required lists must be nonempty. Rates, probabilities and fractions are entered as fractions, not percentages; fractions must be between 0 and 1. Use a single consistent user-selected currency for all amounts; no exchange-rate conversion.
