Formula
Pounds = (sq ft ÷ 1,000) × rate.
Bags = pounds ÷ bag size, rounded up. Cost = bags × your price. Waste is not added on top. If you want extra for overlap, raise the rate.

Grass seed calculator from a seeding rate
This grass seed calculator multiplies area by the pounds per 1,000 square feet you enter. Use it as a seed calculator or a seeding rate calculator for a lawn or a small field. Bag count rounds up. The price per bag is an estimate you type.

Planning estimate from the numbers you enter. Coverage, density, waste and price are assumptions, not a supplier quote or an engineering specification.
How it works
Pounds follow the rate on the bag, not a universal number.
Pounds equal area divided by 1,000, times the rate. Eight thousand square feet at 6 pounds per 1,000 is 48 pounds. A 25 pound bag then means 2 bags, because 48 does not divide evenly, and the bag cost is 2 times your price. New seedings and overseedings use different rates. The 6 pound figure is a placeholder, not a recommendation for a species. Read the bag. A pasture seeding rate in pounds per acre is the same idea: convert the acre to square feet, or divide your per-acre rate by 43.56 to get pounds per 1,000 before you type it.

Example
8,000 square feet at 6 pounds per 1,000.
That is 48 pounds. At 25 pounds a bag you need 2 bags. At $60 a bag the seed estimate is $120. Change the rate and the pounds move in proportion. This seeding rate calculator does not pick the species.
03
Tips
Match the rate to new seed or overseed.
A new lawn often takes more seed than a thickening. Slopes and thin spots take more too. Starter fertilizer is a different product. Use the fertilizer calculator for nutrient pounds. Do not treat the bag price as a quote.

Equipment
A spreader or a tractor carries the rate.
Dengaro arranges financing for a spreader, a tractor, or other farm and landscape equipment. The seed cost is not sent as a loan amount.
Important questions
Know what to expect.
Is 6 pounds per 1,000 the right rate?+
Only if your seed label says so. It is the default so the page has a worked example. Replace it with the seeding rate for the mix you are buying.
How do I use a per-acre seeding rate?+
Divide pounds per acre by 43.56 to get pounds per 1,000 square feet, or type the acreage as square feet (acres times 43,560) and keep a per-1,000 rate.
Why round the bags up?+
You cannot buy a fraction of a sealed bag in this estimate. If your supplier sells by the pound, ignore the bag line and order the pounds.
Does the price include soil prep?+
No. The dollars are bags times the price you entered. Tilling, topsoil, and labor are separate.
