How Calculations Work
This page explains the simple methodology behind the calculator so users can understand where the estimates come from and how to improve them.
The core formula
The calculator works from a straightforward budgeting formula:
Average order value × orders per month = monthly spending
Monthly spending × 12 = yearly spending
Monthly spending × chosen number of months = projected total spending
What to include in average order value
Average order value should usually reflect the final amount you normally pay, not only the menu subtotal. That can include delivery charges, taxes, packaging fees, platform charges, and tips if they are part of your regular order behavior.
Why frequency matters so much
People often focus on expensive single orders, but frequency is what drives most monthly delivery totals. A moderate order value repeated many times can create a larger yearly cost than a few high-value orders spread far apart.
Why the calculator is an estimate, not an account statement
The calculator does not log in to Zomato or fetch your private transaction history. It uses the values you enter manually. That means the output is an estimate designed for clarity and budgeting awareness, not a guaranteed account-level report.
How to make the estimate better
- Use actual recent order totals instead of memory alone.
- Choose a realistic monthly order count based on a normal month.
- Review your order history if your habits change a lot from month to month.
- Use the years setting when you want a lifetime-style estimate.
What the monthly breakdown means
The monthly breakdown shows how the projected spending accumulates over the chosen period. It is useful for comparing projected delivery costs with other monthly budget categories and for seeing how the pattern grows over time.
Use the method with better inputs
If you want stronger results, start by reviewing recent order totals and then apply the calculator with more realistic numbers.
