Farm calculations should be easy to use in the field
When you are checking a poultry house, a calculator should help you answer the question in front of you. It should be readable on your phone, make the result easy to find, and work with the units you use on your farm.
We have updated Poultry Log's free poultry farm calculators with that in mind. The calculator pages have larger controls, simpler headings and a clearer main result. Wider screens put the form and estimate alongside each other; phones follow a straightforward form-then-result layout.
You can use these free tools without creating an account.
Choose Metric or Imperial
Use the Metric or Imperial buttons beside the house-details heading. Switching converts the numbers you have entered and the displayed result. Temperature, lengths, airflow, water volumes and other supported measurements follow the selected system.
For example, you can work with metres, Celsius and litres, or feet, Fahrenheit and US gallons. The underlying estimate stays consistent when you switch. The flock budget supports kilograms and payment rates per kilogram, with a CSV download in your selected units. Monetary figures remain in USD.
Pick the calculator that answers your question
- Minimum ventilation: estimate airflow and fan run time for moisture removal.
- Air leaks: estimate leakage area from your house measurements and fan test.
- Air inlets: review inlet opening needs and the estimated share of air entering through leaks.
- Heating loss: estimate extra propane use and cost attributable to air leaks.
- Litter drying: estimate the time needed to reach your target litter moisture.
- Cooling pads: estimate cooled-air temperature and water use.
- Tunnel airflow: estimate fan capacity for house dimensions and target air speed.
- Flock budget: compare expected grower-paid costs with revenue or grower payment.
Try one question with your own numbers
Start with a question that matters to your next decision: how much extra propane could leakage be costing, or what payment rate would cover the costs in your flock plan?
Choose your units, enter the measurements, and calculate. Review the main estimate, any warnings, and the assumptions when you need more detail. The engineering calculators also provide print and share actions; signed-in users can save an estimate to their farm records.
These are planning estimates. Actual conditions, prices and the completeness of your measurements determine how useful they are. Compare the estimate with what happens on your farm before using it to justify a purchase or a change.
Connect the estimate to the money you actually spend
A useful estimate gives you something specific to check. Actual expense and income records show whether the flock is working out as planned.
Poultry Log lets growers keep those financial records alongside their flock history. Start with one cost you want to understand, record it consistently, and compare the outcome when the flock closes.
