Home › Everyday & Building Calculators
This hub brings together every everyday, building and small-utility calculator on the site in one browsable list, covering renovation, running costs, everyday money, health, dates and quick web tools that do not fit under finance, mortgages or science. If you are planning a job, work out how much paint, concrete, decking, gravel, brick, tiles, plasterboard or insulation you need, or price up a fence, retaining wall or roof pitch before you buy materials. If you are managing everyday costs, compare running costs for an EV, heat pump, appliance, pool or power plan, split a bill, a flat's rent or a group trip evenly, or budget for a wedding, a move or a new baby. Health and fitness tools cover BMI, calories, macros, heart rate and running pace, while date and time tools handle ages, countdowns, business days and time zones. The list also includes handy generators and converters for text, passwords, colours, units and data formats. Click any calculator to open it, enter your own numbers, and get an instant, NZ-relevant result with no sign-up and no cost. Use the list below to browse by name, or press Ctrl+F to jump straight to the calculator you need. Because this category spans so many different tools, treat each result as general guidance for that specific calculator rather than professional advice.
