Home › Everyday & Building Calculators
The everyday and building calculators bring together the tools New Zealanders reach for most, from building and renovating to health, dates, vehicles, energy and shopping. Work out how much paint, concrete, decking or gravel a job needs, split a bill or a flat's rent, check running costs for an EV or a heat pump, count business days, or estimate the cost of a baby, a wedding or a move. There are also fitness and health tools, timers, generators and quick everyday calculators for daily life. Every calculator is free, built for New Zealand conditions and prices where relevant, and needs no sign-up. Browse the full list below and pick the tool you need. These calculators are provided for general guidance and planning only.
