Bird seed cost calculator
Use your bag’s price and net weight, then weigh what you add. A refill log can show the cost of measured additions without guessing how much the birds ate.
Your refill log
Enter the bag’s price and weight for its cost per pound, then log each refill you weigh. Your log starts empty and stays in this browser.
No refills yet. Weigh your next refill to start the log.
What to note at each refill
Note the bag’s price, its net weight and how much you added. Keep the date so you can see how long each refill lasts. If you weigh seed you throw out, log it on its own line; the log never guesses a percentage.
A hopper’s advertised liters or quarts cannot be converted into seed weight without a measurement. Different foods and mixes pack differently, so capacity alone cannot establish a cost per refill.
Old refills keep their old cost
Each logged refill retains the package price and weight you entered for it. Changing to a new bag does not rewrite the earlier entries. Totals show how many observations are complete and how many still lack a date or measurement.
The log stays in this browser when you save it. Public comparison links and analytics exclude refill amounts, dates and history. You can choose to include private history in a local backup from My setup.
