Tomato Bottle Packing and Sterilization Cost Calculator

The app Packaging and Sterilization Cost Calculator for Tomato Bottles is a comprehensive and user-friendly tool that allows you to estimate the total and unit cost of each bottle of passed tomatoes produced, including materials, labor, energy, and additional costs.
Designed for artisanal laboratories, small agri-food businesses, and DIY producers, it helps to understand the true cost of a finished bottle of tomatoes, from packaging to sterilization.💰🍅

🎯 App Objective

Accurately calculate overall packaging costs;
Highlight percentage breakdown between materials, energy, and labor;
Estimate unit cost per bottle;
Provide visual charts and analytical data for more informed production management.

⚙️ How It Works

Enter the number of bottles to be sterilized.
Add the unit costs of bottles and caps/lids.
Specify the sterilization time and the hourly energy cost.
Input data on labor (number of operators and hourly cost).
If desired, add other fixed costs (detergents, water, maintenance).
Press “Calculate Packaging Costs”:
the app calculates and displays:
- Total materials (€)
- Total labor (€)
- Total energy (€)
- Any additional costs
- Overall and unit cost per bottle

📊 Charts and Visual Analysis

🔸 Pie Chart

The chart shows the distribution of total costs:

🔴 Materials (bottles, caps, lids)
🔵 Labor
🟡 Energy
🟢 Other costs

Each section is proportional to the economic weight of that item.
The chart allows you to quickly identify the most costly items so you can focus on the ones that have the most impact on the unit cost.

🔹 Bar Chart (Pro Version)

It will display the evolution of costs over different batches or production runs, with a visual comparison of costs per liter or per bottle.
Perfect for companies that want to analyze economic efficiency over time 📈.

💡 Operational Example

A laboratory needs to package 500 bottles of 700 ml passed tomato:

Bottle cost: € 0.25
Cap cost: € 0.05
Sterilization time: 60 minutes
Hourly energy cost: € 0.40
2 workers × € 12/h
Other costs: € 10

Result:

Materials: € 150.00
Labor: € 24.00
Energy: € 0.40
Total costs: € 184.40
Unit cost per bottle: € 0.37

The pie chart highlights that materials account for over 80% of total costs, suggesting that optimizing purchasing or reusing containers could be beneficial.

🧾 Data Interpretation

Materials Cost (%): often the main item (>70%), direct influence on final price.
Energy Cost (%): increases with long sterilizations or inefficient plants.
Labor (%): depends on automation and number of operators.
Other Costs (%): useful for estimating washing, maintenance, seals, or transport.
Unit Cost (€): key parameter for comparing different seasons or deciding the selling price.

🚀 Operational Benefits

Clear and immediate calculation of the real cost per bottle;
Detailed analysis by expense item;
Visual graphs that make it intuitive to understand where the most is being spent;
Strategic support for optimizing time, energy, and labor;
Perfectly integrable with other UtileApp apps for a complete management of the production cycle (yield, labeling, logistics).

⚠️ Warnings

The entered values are customizable: for reliable results use up-to-date actual costs.
The app does not permanently save data (browser session).
For industrial or commercial use, also consider indirect costs (amortization, waste, transportation).

🌟 Future Developments

Upcoming features planned:

📈 Comparative chart for production batches;
🧾 PDF/CSV report with cost and margin summary;
🧮 Calculation of precise energy cost (kWh/l);
🔗 Direct link with the app “Necessary Bottles and Jars Calculator” for automatic import of packaging volumes;
⚙️ Scenario simulator (e.g., variations in energy cost or sterilization time).

This app is the economic heart of the tomato transformation process: turn your production data into clear decisions, real numbers, and readable charts 🍅📊
