Frying Oil Top-Up Cycle Calculator
Fryer oil inventory falls through food absorption, drag-out, filtration loss, spills, and scheduled discard. This calculator separates daily operating loss from a periodic replacement fraction, then estimates top-up and purchase volume over a planning period. Oil quality, allergen control, fire safety, and discard timing must follow the equipment, product, and food-safety program.
Planning estimate only. Check measurements and real-world constraints before buying materials or making a commitment.

Your results
Daily top-up estimate
1.06 L
Food, drag-out, and filtration loss.
Cycle oil purchase
11.44 L
Top-up plus scheduled replacement volume.
Scheduled discard volume
4.00 L
Policy-based discard, separate from daily loss.
How the calculation works
The calculator applies this relationship to the inputs above. Keep every measurement in the unit shown.
Worked example
Use this example to check the calculator by hand before relying on a result.
Assumptions behind the result
- • Oil density is approximated near one kilogram per litre.
- • Loss rate includes food absorption and drag-out.
- • Production is stable.
- • Replacement policy is independently validated.
- • Waste oil is handled safely and legally.
Mistakes that change the answer
- • Treating top-up as proof oil remains good.
- • Ignoring filtration loss.
- • Mixing fryer capacity with daily consumption.
