Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Delivery fee | Order total |
|---|---|---|
| $80 · 7% | $5.60 | $85.60 |
| $30 · 10% | $3.00 | $33.00 |
| $200 · 5% | $10.00 | $210.00 |
| $15 · 15% | $2.25 | $17.25 |
How This Calculator Works
Enter the order subtotal and the fee percentage. The calculator multiplies the two to find the delivery fee, then adds it to the subtotal to give the order total billed.
The Formula
Percentage Add-On
Rate is the tax or tip percentage applied to the amount
Worked Example
An $80 order with a 7% delivery fee adds $5.60, for a total of $85.60. A flat fee instead of a percentage would charge the same amount regardless of subtotal — bad value on small orders, better on big ones.
Key Insight
Percentage delivery fees scale with the order, which feels fair on small baskets but punishes larger ones. A 10% fee on a $30 lunch is $3; on a $200 grocery order it is $20 — the cost of convenience grows with the bill.
Frequently Asked Questions
What is a delivery fee?
A charge added to an order to cover the cost of bringing it to you — fuel, the driver's pay, and platform overhead. It can be flat, percentage-based, or a mix.
How is a percentage delivery fee calculated?
Multiply the order subtotal by the fee percentage, then add the result to the subtotal. A 7% fee on $80 is $5.60, for a total of $85.60.
Is the tip included?
No. Delivery fees and tips are usually separate — the fee covers the service; the tip is for the driver. Tips are not included in the calculator's figure.
Is a flat fee or a percentage better?
It depends on order size. Flat fees are cheaper on big orders; percentages are cheaper on small ones. Many platforms charge whichever is higher.
Why do delivery fees keep going up?
Driver pay, fuel, and platform economics are the main drivers. Fees rose sharply when delivery shifted from a niche to a default channel, then again when food costs climbed.

Methodology & Review
The delivery fee is the order subtotal multiplied by the fee percentage; the total adds the fee to the subtotal. Flat fees, service fees, and tips are not modeled here — this covers percentage-based delivery fees only.
