About Zamcalc
Zamcalc is a free, independent financial tools platform built specifically for Zambia, and a product of Zamcalc Technologies, a registered Zambian company. Every calculator uses current official rates from Zambian authorities - ZRA, NAPSA, NHIMA, ZESCO, ERB, HELSB, Bank of Zambia, and others - and is updated whenever laws or tariffs change.
Why Zamcalc exists
Zambian workers, business owners, and individuals regularly need to calculate tax deductions, utility bills, loan repayments, and other financial figures. The official sources for these numbers are scattered across government websites, PDFs, and gazette notices. Zamcalc brings them together into simple, accurate tools that anyone can use for free.
What we cover
The platform spans more than 30 calculators and tools across tax, payroll, utilities, transport, loans, and savings - PAYE income tax, VAT, turnover tax, property transfer tax, NAPSA and NHIMA contributions, HELSB loan repayments, ZESCO electricity bills, solar kit costs, mobile money fees, loan repayments, savings goals, compound interest, government bonds, treasury bills, vehicle import duty, gratuity, and payroll summaries - with more added regularly. Zamcalc is free on the web and now available as a free Android app on Google Play, with every calculator working fully offline.
How we keep rates current
Every figure in Zamcalc traces back to its official source - the tax bands, contribution ceilings, utility tariffs, and duty rates published by ZRA, NAPSA, NHIMA, ZESCO, the Energy Regulation Board, and the Bank of Zambia. Each calculator cites the source it relies on, rates are held as a single source of truth, and they are revised whenever a law or tariff changes - so the figures you see reflect what is currently in force, not last year's. We are also building automated monitoring of these official sources into our pipeline, so rate changes are detected and applied quickly rather than depending on manual checks alone.
Who builds Zamcalc
