Why do project calculators usually recommend a buffer?
Because real-world jobs involve cuts, waste, uneven surfaces, and ordering inefficiencies that simple formulas do not fully capture.
Can I use these tools for exact supplier orders?
They are best used as planning estimates, then checked against supplier packaging, local pricing, and job-site realities.
Which utility calculator should I use for home energy budgeting?
Start with electricity cost for a quick running-cost estimate and appliance energy if you want to focus on annual consumption for one device.
