Tithe & Offering Calculator

A tithe is traditionally defined as one-tenth (10%) of a person's income given to a church or religious organization as an act of worship, obedience, and support for the community of faith. The word "tithe" comes from the Old English "teogotha," meaning "tenth," and the practice has deep roots in biblical tradition — tithing is mentioned in Genesis (Abraham's tithe to Melchizedek), Leviticus (the Levitical tithe for supporting the priesthood), and Malachi (where God challenges Israel to "bring the whole tithe into the storehouse"). While the specific percentage and calculation basis (gross vs. net income) vary by denomination and personal conviction, 10% of income remains the most widely recognized benchmark across Christian traditions worldwide. This tithe calculator makes it easy to determine your tithe amount based on your actual income and chosen parameters.

Whether to tithe on gross income (your total earnings before taxes and deductions) or net income (your take-home pay after taxes) is one of the most common questions about tithing, and the answer varies by denomination and personal conviction. Those who advocate tithing on gross income argue that you should give from your "first fruits" — the full amount before the government takes its share. Those who advocate net income tithing argue that since taxes are mandatory and not discretionary spending, your tithe should be based on what you actually have available. Many pastors suggest starting where you are comfortable and growing your generosity over time. This tithe and offering calculator lets you toggle between gross and net income with a single click, so you can see both amounts side by side and make an informed, prayerful decision about which approach aligns with your convictions.

Yes. This tithe and offering calculator supports multiple additional offering categories beyond the base tithe. You can add custom categories with descriptive labels — for example, a missions fund, building fund, benevolence offering, pastor's appreciation gift, youth ministry support, or any other cause you want to contribute to. Each category has its own dollar amount field, and the summary section combines your tithe and all additional offerings into a clear total giving figure. This feature is especially useful for families who give to multiple causes and want to see their total charitable commitment in one place. The calculator also shows your combined giving as a percentage of your income, helping you understand the full picture of your generosity.

No. This tithe and offering calculator is designed with absolute financial privacy as a core principle. All calculations happen in real time in your web browser using simple JavaScript math — nothing is saved to localStorage, cookies, or any form of persistent storage. When you close the browser tab, all the numbers you entered are gone completely. No data is ever transmitted to any server, cloud service, analytics platform, or third-party system. There is no account system, no login, and no tracking of any kind. Your income information and giving calculations remain entirely on your screen and in your control. This makes it a safe tool for planning your charitable giving without any risk of your financial information being stored or exposed.

This tithe and offering calculator supports four common pay frequencies to match your income schedule: weekly (paid every week, typically 52 paychecks per year), bi-weekly (paid every two weeks, typically 26 paychecks per year), semi-monthly (paid twice a month, 24 paychecks per year), and monthly (paid once a month, 12 paychecks per year). You can also enter your annual income directly. The tool annualizes your income based on the selected frequency and then calculates your tithe on the annualized amount, displaying results as both a per-period amount (matching your paycheck frequency) and an annual total. This ensures accuracy regardless of how you receive your income and makes it easy to set up recurring giving with your church that aligns with your pay schedule.

The tithe calculator multiplies your selected income base (gross or net) by the tithe percentage you specify (default 10%) and divides it according to your pay frequency to show both per-period and annual amounts. The formula is straightforward: if you earn $5,000 per month gross and tithe at 10%, your monthly tithe is $500 and your annual tithe is $6,000. If you switch to net income of $3,800 per month, the tithe drops to $380 monthly or $4,560 annually. You can adjust the tithe percentage up or down from the default 10% to match your personal conviction — some people give 5% as they build toward a full tithe, while others give 12% or 15% as an expression of generous stewardship. Any additional offerings you add are calculated separately and combined with the tithe in the summary.

Yes. This tithe and offering calculator is completely free to use with no advertisements, no premium tier, no account registration, and no restrictions on usage. You can calculate your tithe and offerings as many times as you need, adjust any parameters, and compare gross vs. net scenarios without paying anything. The tool runs entirely in your browser using simple JavaScript calculations with no server-side processing, which means there are no operating costs to maintain and it will remain free permanently. It is designed to be a helpful, accessible resource for anyone planning their charitable giving, regardless of their denomination, income level, or technical expertise.

In Christian financial stewardship, a tithe and an offering are related but distinct concepts. The tithe is the baseline 10% of income that many Christians consider a minimum standard of giving, based on the biblical principle of returning a tenth to God. An offering (sometimes called a "free-will offering" or "love offering") is any amount given above and beyond the tithe — it is voluntary, discretionary, and often directed toward specific causes such as missions, building funds, disaster relief, or community outreach. Think of the tithe as the foundation and offerings as the additions you build on top of it. This calculator distinguishes between the two by calculating your tithe first and then allowing you to add separate offering categories, giving you a complete view of your total giving commitment.

Absolutely. While the terminology of "tithe" and "offering" comes from the Christian tradition, the underlying calculation is a simple percentage of income, which applies universally to any form of charitable giving. You can use this tool to calculate Islamic Zakat-inspired giving, Jewish tzedakah, Sikh dasvandh, secular charitable donations, or any other tradition of proportional generosity. Simply adjust the percentage from the default 10% to whatever amount aligns with your tradition or personal goals, and use the additional offering categories to itemize specific charities or causes. The calculator does not enforce any particular religious framework — it is a practical financial planning tool that helps anyone determine how much they can give based on their income.

This tithe and offering calculator is an excellent starting point for creating a comprehensive giving budget. Start by entering your actual income amount and selecting whether you want to calculate based on gross or net. Set your tithe percentage at your target level (whether that is the traditional 10% or a different amount). Then, use the additional offering categories to add each specific cause or organization you want to support — for example, $200 per month to your local church building fund, $50 per month to a missions organization, and $100 per month to a local food bank. The summary section will show you the total combined amount and what percentage of your income it represents. You can screenshot or note down these numbers and use them to set up recurring transfers or giving through your church's online platform, making your charitable commitments consistent and sustainable.
