Zakat / Tithe Calculator — Free
Work out one figure, right here. Zakat mode nets your zakatable assets against your liabilities, checks them against your own nisab, and shows the amount at the rate you set. Tithe mode totals your income and applies your rate. You set every threshold and rate — the tool only does the arithmetic — and nothing is saved or sent. Use it in your browser, or download the fillable spreadsheet to keep.
Zakat / Tithe Calculator
Net wealth × your rate
You set every threshold and rate; this tool only does the arithmetic on the figures you enter. Pre-filled with an example — replace it with your own. Runs entirely in your browser; nothing is saved or sent. It is not tax, financial, or religious advice, and not a substitute for a tax professional or a religious authority — follow the method you trust.
Take it with you — free, no signup
Direct download. No email, no account — just the files.
What it does
- Zakat: nets your zakatable assets minus liabilities, tells you whether you've reached your nisab, and shows the amount at your rate.
- Tithe: totals your income and applies your rate — on whichever basis, gross or net, you've decided to use.
- You set your own nisab, basis, and rate — it never decides your obligation for you.
- Runs entirely in your browser; nothing is saved or sent. Or download the fillable spreadsheet (Excel, Google Sheets, or LibreOffice).
Own it, don't rent it
Ready to organize a whole year of giving?
This free tool computes one figure. The full workbook is where a whole year of giving gets organized: a giving log that totals your giving, the tax-deductible share, and cash versus non-cash; a year-end summary with a by-category breakdown for tax time; a non-cash donation log; and richer zakat and tithe worksheets that pull what you've already given from the log — an 8-tab workbook you own (Excel, Google Sheets, or LibreOffice) plus four guides and a one-click Google Sheets copy.
A one-time purchase you keep and reuse — the owned workbook between a blank spreadsheet and a rented giving app.
A calculation tool, not tax, financial, or religious advice, and not a substitute for a tax professional or a religious authority. You set every threshold and rate; follow the method you trust. Free to use; please don't resell or redistribute.
