The calculator uses the numbers you enter. The calculator subtracts the ingredient cost of one meal cooked by you from the average order price, then multiplies that difference by the number of orders. The result shows how much more, or less, takeout orders cost than the same meals cooked by you. From the meals you already cook at home it computes a separate ingredient cost; that amount is not in the primary result. From the waste percent it computes the cost of food thrown away from delivery. In the first example the result is 64 {{currency}} more than the same meals cooked by you.
The five form fields are home meals, orders, order price, ingredients per meal, and waste. Comparison with meals cooked by you means: The calculator subtracts the ingredient cost of one meal from the average order price and multiplies the difference by the number of orders. In the first example the result is 64 {{currency}} more than the same meals cooked by you. Separate home-cooking cost means: This is the ingredient cost of the meals you already cook at home. That amount is not subtracted from the primary result. Waste means: The percent of delivered food you throw away. Multiplied by the order cost it gives the amount thrown away. In the first example 10% of 96 {{currency}} is 9.60 {{currency}}.
The second example gives 23 {{currency}} more than the same meals cooked by you. The third example gives 224 {{currency}} more than the same meals cooked by you. Four orders at 24 {{currency}} cost 96 {{currency}}. The same meals cooked by you, at 8 {{currency}} in ingredients each, cost 32 {{currency}}. The result shows how much more the takeout orders cost: 64 {{currency}} more than the same meals cooked by you.
This is not money back in your account. The calculator only compares those orders with the same meals cooked by you. It does not place an order and does not read a receipt. Your hourly rate is optional and is not a contract wage.
