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.
