Calculators

Every number these tools use comes from a published rate, and each page shows you the source and the arithmetic.

• Grass seed calculatorHow many pounds you need for your lawn, by grass type, for a new lawn or for overseeding.
• Mulch calculatorCubic yards and bags, at the depth extension services actually recommend.
• Fertilizer calculatorPounds of the bag you bought for a target of nitrogen per 1,000 sq ft.
• Lawn size calculatorTurn an odd-shaped yard into the square footage every other calculation needs.
• Sprinkler run time calculatorThe tuna can test: measure what your heads put down, then set run times by zone.
• Sod calculatorPallets and square feet — with your farm's actual pallet size, not a blog's round number.
• Topsoil calculatorCubic yards and bags for lawn prep and till-in amendments, at Penn State–published depths.
• Lawn care pricing calculatorWhat to charge per mow from your wage, minutes, and overhead — Iowa 2025 custom-rate medians as a regional survey, never a marketplace $30/lawn.
• Gutter cleaning pricing calculatorCost-plus for this house from your wage and timed minutes — no marketplace gutter flat rates, no invented minutes table.
• Snow removal pricing calculatorPrice a driveway or walk from your costs and stopwatch. Iowa farm loader/blade/blower medians are context only, not a residential list price.
