About the Tithe Calculator
This tithe calculator works out how much to give from each paycheck. Enter your gross pay and take-home pay for your pay period, choose whether you tithe on gross (before tax) or net (after tax) income, and it shows the tithe per paycheck along with weekly, monthly and yearly equivalents. The traditional tithe is 10%, but you can set any percentage you have committed to.
Tithing on gross or net income is a personal and church-tradition question — many give on gross income as the “firstfruits” before taxes, while others give on what they actually take home. Seeing both numbers side by side makes that decision clearer. You can also add regular offerings beyond the tithe, such as missions or a building fund.
The results include your total yearly giving, the share of take-home pay it represents and what remains from each paycheck, so you can build giving into a realistic budget. In the US, cash gifts to qualifying churches can reduce federal income tax: under the 2025 tax law (One, Big, Beautiful Bill), from tax year 2026 people who take the standard deduction may deduct up to $1,000 of cash gifts ($2,000 for married couples filing jointly), and itemizers can deduct only the part of their gifts above 0.5% of adjusted gross income. This calculator does not estimate the tax saving; keep records of every contribution.
With the default inputs, the tithe per paycheck is $300.00. Change any value above to recalculate instantly.
How to use the tithe calculator
- 1Choose how often you are paid.
- 2Enter your gross pay and take-home pay for one pay period.
- 3Pick whether you tithe on gross or net income, and the percentage.
- 4Add any regular offerings beyond the tithe.
- 5Use the per-paycheck figure when you give and the yearly total for your budget.
Formula and method
The tithe per paycheck is your gross or take-home pay for the period multiplied by your tithe percentage (10% by default). Yearly giving multiplies that by the number of pay periods in a year: 52 for weekly, 26 for every two weeks, 24 for twice a month, 12 for monthly and 1 for yearly.
Monthly and weekly figures are derived from the yearly total so they are accurate regardless of pay schedule — a biweekly paycheck is not the same as half a month. Total giving adds any regular offerings, and the remaining amount is take-home pay minus the tithe and offerings.

Worked examples
10% of a $3,000 biweekly gross paycheck
Ten percent of $3,000 gross is $300 per paycheck. With 26 paychecks that is $7,800 a year, or $650 a month. Tithing on the $2,300 take-home instead would be $230 per paycheck, and after a gross-based tithe $2,000 of take-home pay remains.
Tithing on take-home pay
On the $2,300 take-home paycheck, a 10% tithe is $230. Over 26 paychecks that is $5,980 a year — about $498 a month and $115 a week.
Monthly salary with a $50 offering
A 10% tithe on $3,400 of monthly take-home pay is $340. Adding a $50 offering brings giving to $390 a month, $4,680 a year, and leaves $3,010 of take-home pay each month.
Frequently asked questions
How much is a tithe?+
A tithe traditionally means one tenth, or 10%, of your income. On $50,000 a year a full tithe is $5,000 a year, which is about $417 a month or $192 per biweekly paycheck.
Should I tithe on gross or net income?+
Churches and Christian traditions differ, and the Bible does not mention income taxes. Many people tithe on gross income as the “firstfruits”, others on take-home pay. Choose what fits your convictions and budget and apply it consistently.
Is tithing tax deductible?+
In the US, cash gifts to qualifying churches are deductible within limits. Starting with tax year 2026, taxpayers who take the standard deduction can deduct up to $1,000 of cash gifts ($2,000 married filing jointly); gifts to donor-advised funds do not qualify for that deduction. Itemizers deduct gifts on Schedule A above a floor of 0.5% of AGI (amounts under the floor can carry forward), generally up to 60% of AGI for cash gifts to churches and other public charities. Keep a receipt or written acknowledgment for any single gift of $250 or more.
What is the difference between tithes and offerings?+
The tithe is the regular 10% (or your chosen share) given to your local church. Offerings are gifts above the tithe, such as missions, building funds, benevolence or special appeals.
How do I start tithing if 10% feels like too much?+
Many people start with a smaller percentage they can give consistently and increase it by 1% at a time as debts are paid down or income grows. Building giving into your budget first makes it easier to keep up.
