Tithe Calculator

Calculate Christian tithe (10% of income) with weekly, monthly, and annual breakdowns plus lifetime giving projection.

RELIGION · SOCIAL

Calculate your Christian tithe — 10% of income — with weekly, monthly, and annual breakdowns plus a lifetime giving projection over 10, 20, and 40 years.

Enter income at any frequency (weekly, biweekly, semimonthly, monthly, annual), choose gross (pre-tax) or net (take-home) as your basis, set tithe percentage (default 10%), and optionally add a free-will offering on top. Output covers per-period giving and a multi-decade projection to help model lifetime stewardship.

Disclaimer: Theological views on tithing differ across denominations — some teach 10% gross, others 10% net, others a free-will proportional model. US contributions to a 501(c)(3) church are generally tax-deductible if you itemize on Schedule A.

Biblical Tithing — Quick Guide

The tithe (literally "a tenth") appears throughout Scripture: Abraham gives a tenth of his spoils to Melchizedek in Genesis 14:20, Jacob vows a tenth in Genesis 28:22, and the Mosaic Law commands a tenth of every harvest in Leviticus 27:30.

Malachi 3:10 invites believers to "bring the whole tithe into the storehouse" — most US churches teach this as 10% of pre-tax (gross) income given to the local church. Free-will offerings (above the tithe) support missions, the poor, and special projects.

In 2026, the average US Christian household gives roughly 2.5% of income — well below the biblical 10%. This calculator helps you plan a consistent rhythm so giving becomes a habit, not an afterthought.

Educational tool only. Theological views on tithing differ across denominations — some teach 10% gross, others 10% net, and others a free-will proportional approach. Charitable contributions to a 501(c)(3) church or ministry are generally tax-deductible in the US if you itemize on Schedule A.
