What This Biogas Plant Calculator Does
This Biogas Plant Calculator helps farmers estimate the potential benefits of installing a biogas plant using animal dung and agricultural waste (agri-waste). It focuses on two main outcomes that matter most to farmers: fuel savings and fertilizer production.
By entering details such as type and number of animals, daily waste availability, family size, and type of use (cooking or cooking plus electricity), this tool provides an easy-to-understand estimate of:
- Daily and annual biogas production
- Approximate cooking time available from biogas
- LPG or fuel savings per year
- Possible electricity generation from biogas
- Bio-slurry (organic fertilizer) production and its value
- Potential carbon credits (where applicable)
- Your total annual savings in local currency
This calculator is designed for farmers in India and abroad who want to plan a biogas plant and understand its economic and practical benefits before investing.
Why Biogas Is a Smart Choice for Farmers
Biogas plants convert animal dung and organic farm waste into useful energy and fertilizer. This helps farmers:
- Reduce dependence on LPG, diesel, or electricity
- Save money on cooking fuel and farm energy
- Produce high-quality organic fertilizer (bio-slurry)
- Improve soil health and reduce chemical fertilizer use
- Manage waste in an eco-friendly way
- Reduce greenhouse gas emissions and support climate-friendly farming
In many regions, biogas projects are also supported through government subsidies or carbon credit programs, which can further improve the financial benefits.
What Information You Need to Enter
To get a practical estimate, the calculator asks for:
Animal and Waste Details
- Type of animals: Cow, buffalo, goat, horse, pig, donkey, chicken, etc. (you can select up to three types)
- Number of animals: For each selected animal type
- The calculator then automatically estimates daily waste (dung or wet waste) based on standard values
Household and Usage Details
- Family members: To estimate cooking gas requirement
- Type of use: Cooking only, or cooking plus electricity generation
Economic Details
- LPG cylinder price or fuel cost: To estimate annual fuel savings
- Fertilizer value of bio-slurry: To estimate savings from replacing chemical fertilizers
- Government subsidy (if applicable): Depends on plant size and local schemes
- Carbon credit price (optional): For countries or projects that can earn carbon credits
Using these inputs, the calculator estimates your energy, fertilizer, and financial benefits.
Example to Understand the Output
If a farmer has 4 cows (about 40 kg of dung per day), the calculator may show results such as:
- Daily biogas production: around 1.6 m³ per day
- Cooking time: about 4 to 5 hours per day
- LPG savings: about 10 to 12 cylinders per year
- Electricity generation: a few units (kWh) per day and per year
- Bio-slurry production: approximately 5 to 7 tons per year
- Total annual savings: a combined value from fuel, fertilizer, and carbon benefits
These values help the farmer understand whether a biogas plant is useful and economically attractive for their farm.

Biogas Plant Calculator for Farmers
This calculator helps you estimate biogas production, fuel savings, electricity generation, fertilizer (bio-slurry) value, carbon credits, subsidy benefit, and total annual savings from a biogas plant using animal dung and agricultural waste.
1) Location & Currency
2) Animals & Daily Waste
Choose up to three animal types and enter the number of animals. Daily waste will be estimated automatically.
3) Household & Usage
4) Economic Inputs
How to Read the Results
The results section shows you:
- Total daily waste: Estimated amount of dung or wet waste available per day
- Daily biogas production: How much gas your plant can produce per day
- Cooking time: Approximate hours of cooking possible per day using biogas
- LPG or fuel savings: How many LPG cylinders (or equivalent fuel) you can save per year
- Electricity generation: Approximate electricity you can produce per day and per year
- Bio-slurry production: Amount of organic fertilizer produced per year
- Fertilizer savings: Value of fertilizer saved by using bio-slurry instead of chemical fertilizers
- Carbon credits: Estimated emission reduction and its possible value
- Total annual savings: Combined value of fuel, fertilizer, and carbon benefits
This gives you a complete picture of the benefits of installing a biogas plant.
Practical Tips for Farmers
- Use accurate numbers for animals and waste for better estimates
- Maintain the biogas plant properly to get consistent gas production
- Use bio-slurry in your fields to reduce chemical fertilizer costs
- Check local government subsidy schemes for biogas plants
- If available in your country, explore carbon credit programs
Important Notes
- Actual gas production depends on animal feed, waste quality, temperature, and plant design.
- Savings depend on local fuel prices, fertilizer prices, and how efficiently you use the gas and slurry.
- Subsidy and carbon credit rules vary by country and by scheme.
- This calculator provides estimates, not guaranteed results.
Disclaimer
This calculator provides approximate estimates for educational and planning purposes only. It does not guarantee gas production, savings, subsidy approval, carbon credit income, or financial returns. Actual results may vary due to animal diet, plant size and design, operating conditions, local prices, government policies, and market conditions. Always consult a biogas expert or local authority before making investment decisions.
