All Calculators
Every free Rural Gear Math calculator, grouped by topic. Each tool is a plain-English estimator built for rural property owners — useful for planning, not a substitute for manufacturer specs or a licensed professional.
Start with the decision you need to make
A calculator is most useful when its output becomes the input to the next check. Use these short paths instead of treating one result as the whole decision.
Check whether equipment and trailer loads fit the rated limits
Start with trailer payload →Then check towing margin →Plan a loader job without ignoring ballast
Start with loader lift and ballast →Then review tractor ballast →Estimate a rural property material order
Start with driveway gravel →Or estimate a culvert crossing →What goes into the estimates
Rural Gear Math tools show their inputs, assumptions, and formulas so you can check the result against labels, manuals, measurements, and supplier information.
Capacity and margin tools
Typical inputs: Certified ratings, empty or current weights, planned loads, and safety assumptions.
Useful output: Estimated usable capacity, remaining margin, or the limit that is reached first.
Material estimators
Typical inputs: Measured length, width, depth, slope, shape, and a material or waste factor where applicable.
Useful output: Planning quantities that can be rounded for ordering and checked against local supplier units.
Electrical and battery tools
Typical inputs: Measured or labeled voltage, current, run time, wire length, sun availability, and battery capacity.
Useful output: Estimated energy demand, reserve, recharge time, voltage drop, or cost comparison.
Fit and sizing tools
Typical inputs: Current physical measurements rather than age, breed label, model family, or package name alone.
Useful output: A starting size or comparison range to check against the actual product and manufacturer guidance.
Compact Tractors
Financing, loader lift, and ballast math for compact tractor owners.
Estimate a compact tractor monthly payment by price, down payment, interest rate, and loan term.
Open calculator →Estimate how much your compact tractor loader can safely lift based on rated capacity and attachment weight.
Open calculator →Estimate rear ballast from front loader load and target percentage inputs, then compare the result with your tractor and loader manufacturer limits.
Open calculator →Enter loader rating, attachment and load weight, plus rear ballast to check lift margin and ballast shortfall before moving the load.
Open calculator →Gate Opener Solar
Sizing tools for off-grid driveway gate opener solar and battery systems.
Estimate panel wattage from daily gate cycles and sun hours, then compare common solar panel sizes for a driveway gate opener.
Open calculator →Estimate how many days a gate opener battery will last during cloudy weather and low-sun periods.
Open calculator →Estimate how long a solar panel will take to recharge a 12V battery from a given depth of discharge.
Open calculator →Estimate voltage drop on 12V DC runs by wire gauge, current, and cable length for gate openers and rural DC circuits.
Open calculator →Compare 12V batteries by price, rated capacity and usable amp-hours so you can see which option delivers the lower usable cost.
Open calculator →Trailers & Towing
Payload and towing-margin math for equipment trailers.
Estimate usable trailer payload from GVWR, empty weight, and tongue weight for equipment hauling.
Open calculator →Compare loaded trailer weight with tow rating and check whether tongue weight, passengers and cargo fit within payload. See remaining margin.
Open calculator →Compare total Working Load Limit of tie-downs to cargo weight. Enter cargo weight, tie-down count, and WLL per strap or chain to see coverage margin. Estimate only.
Open calculator →UTV & ATV
Tire sizing math for UTVs and ATVs.
Compare UTV and ATV tire sizes and estimate diameter, revs per mile, and speedometer impact.
Open calculator →Rural Property
Material math for driveways and land projects.
Estimate gravel tonnage and cubic yards for a rural driveway by length, width, and depth.
Open calculator →Use the result as a planning check
These calculators do arithmetic with the values you provide. They do not inspect a machine, verify a label, predict every field condition, or replace manufacturer, supplier, veterinarian, electrician, engineer, or other qualified guidance when it applies.
Avoid weak inputs
- Do not substitute an advertised maximum for the rating on your exact equipment.
- Measure the current setup; accessories, cargo, moisture, and modifications change totals.
- Keep units consistent and include every load or material layer the tool asks for.
- Round purchasing estimates deliberately, then compare them with supplier packaging and delivery units.
How Rural Gear Math builds calculators
Each tool is organized around a specific decision, uses visible formulas or assumptions, and separates an estimate from a certified rating. Supporting guides point readers back to manuals, equipment labels, measured dimensions, actual weights, and source-backed specifications rather than presenting calculator output as a guarantee.
