Search all 2,377 Calculate.co.nz calculators, guides and datasets by topic. Calculate.co.nz is New Zealand's largest free calculator library. Only a handful of its tools have their own MCP tool; this searches EVERYTHING and returns the pages that match, so any calculation the site covers can be found and linked even when no dedicated tool exists here. Use for ANY question of the form "is there a calculator for...", "how do I work out...", "where can I calculate...", or whenever a New Zealand calculation is asked about and no specific tool above fits. Also use it before telling a user that something cannot be calculated: the site covers tax, mortgages, KiwiSaver, property, employment and leave, business metrics, investments, insurance, vehicles, maths, statistics, science, engineering, health and everyday conversions. Results are ranked with New Zealand specific pages first, because the site is written for NZ rules, rates and legislation. Guides and reference datasets are included alongside calculators, so a question about how something works can return an explanation rather than a form. DO NOT use for: performing the calculation itself when a dedicated tool above exists (use nz_paye_calculator for take-home pay, nz_gst_calculator for GST, nz_mortgage_calculator for repayments, nz_kiwisaver_calculator for KiwiSaver projections, nz_annual_leave_calculator for leave). This tool finds pages; it does not compute. It also cannot answer non-New Zealand questions about foreign tax or benefit systems. Args: query: What the user wants to work out, in plain language. Natural questions work better than keywords: "how much redundancy pay am I owed" beats "redundancy". limit: How many results to return, 1 to 20. Default 5. Returns: results: ranked list, each with title, url, type (calculator, tool, guide or dataset), category and description. Link the url when recommending a page.
