How it works
Field size times the rate gives the pounds of seed. Multiply that by the price per pound to get the seed cost.
Seeding rates depend on the crop and the planter. Check the seed tag or your seed dealer's guide for the rate you plan to use.
Worked example
A field of 5 ac sown at 100 pounds per acre needs 500 pounds of seed, which costs $425.00 at the price you entered.
Questions
Do I need to know the bag size?
Enter the price per pound from the tag or bag. The calculator works in pounds, so bag sizes do not change the answer.
Why can the bill be more than the math?
Seed is often sold in fixed bag weights, so the order can round up to the next full bag. Ask your dealer about bag sizes.
Should I buy extra seed?
Some growers add a little for poor germination or uneven ground. Compare the germination figure on the tag before you decide.
