A tithe calculator tells you exactly how much to give based on your income, pay frequency, and chosen tithe percentage — so you can focus on faithful giving rather than mental arithmetic. Enter your income per period, select whether to base giving on gross or net pay, and the tool returns your tithing amount for every pay cycle, month, and year at once.

What Is a Tithe Calculator?
A tithe calculator is an online tool that computes a biblical tithe or any charitable giving amount from your income. The word tithe comes from an Old English term meaning “one tenth,” and it refers to the practice of giving 10% of earnings to a local church or ministry as an act of Christian stewardship and worship.
While the traditional standard is 10%, many believers today choose to give more or less depending on their circumstances, denomination, or season of life. A tithing calculator accommodates that flexibility — it is not locked to any single percentage.
It is also worth distinguishing a tithe from an offering. A tithe is a structured, recurring commitment usually set at a fixed percentage of income. An offering is an additional, voluntary gift given above the tithe — often spontaneous or occasion-based. This tool handles the tithe portion of Christian giving; any offering on top of that is separate.
How a Tithe Is Calculated?
The Tithe Formula
The core tithe formula is straightforward:
Tithe Amount = Income per Period × Tithe Percentage
For a traditional 10 percent tithe:
Tithe Amount = Income per Period × 0.10
If your weekly paycheck is $1,200, your weekly tithe at 10% is $120. If you earn $5,000 per month, your monthly tithe is $500. The arithmetic is simple — the real decision is what counts as “income” and which percentage to apply.
Gross Income Tithe vs. Net Income Tithe
This is the most common question in Christian giving discussions, and the answer is a matter of personal conviction rather than a single scriptural command.
Tithing on gross income means calculating the tithe percentage before taxes and deductions are removed. Proponents point to the biblical “firstfruits” principle — that giving comes from the top of what you earn, not the remainder after expenses. The calculator’s Gross Income mode applies this approach.
Tithing on net income means calculating from take-home pay after taxes, Social Security, health insurance, and other deductions. Some believers argue this reflects the income they actually receive and can steward. The calculator’s Net Income mode supports this.
There is no universally mandated rule. What matters most is consistency and intentionality. Choosing gross or net and sticking to it is far more meaningful than toggling back and forth.
How to Use the Tithe Calculator?
The calculator interface has five inputs. Work through them in order from top to bottom:
- Select “Calculate On.” Choose Gross Income (before taxes and deductions) or Net Income (take-home pay). The selector at the top of the form defaults to Gross Income, which reflects the traditional firstfruits approach.
- Choose your pay frequency. Pick how often you are paid: Weekly, Bi-Weekly, Monthly, or Annually. This tells the calculator which time unit your income figure represents, so it can project the right annual and per-period totals.
- Enter your income per period. Type your salary tithe base in the “Your Income Per Period” field. If you chose Weekly, enter your weekly gross or net earnings. If you chose Monthly, enter your monthly figure. The field accepts dollar amounts; include cents if needed.
- Add any additional income sources (optional). Click + Add source to include side income, freelance earnings, rental income, or any other stream you want factored into your giving. Each source is added individually and the calculator sums them automatically.
- Set your tithe percentage. Drag the slider or type directly into the percentage box on the right. The slider runs from 1% to 30%, with the midpoint marker at the traditional 10% tithe. Adjust this to match your personal commitment or denominational guideline.
- Click “Calculate My Tithe.” Results appear immediately, showing your tithing amount for the selected pay period. Use the figures to set up recurring giving through your church’s portal or auto-transfer.
Worked Example — Tithe from Salary at Different Pay Frequencies
The table below illustrates how the tithe formula works across common salary tiers and pay periods at the traditional 10% rate. All figures assume gross income tithing.
Annual Gross Income | Weekly Tithe | Bi-Weekly Tithe | Monthly Tithe | Yearly Tithe |
$30,000 | $57.69 | $115.38 | $250.00 | $3,000 |
$50,000 | $96.15 | $192.31 | $416.67 | $5,000 |
$75,000 | $144.23 | $288.46 | $625.00 | $7,500 |
$100,000 | $192.31 | $384.62 | $833.33 | $10,000 |
$150,000 | $288.46 | $576.92 | $1,250.00 | $15,000 |
Hourly wage example: An employee earning $20/hour working 40 hours per week has a weekly gross of $800. At 10%, their weekly tithe is $80, their monthly tithe is approximately $346.67, and their yearly tithe is $4,160.
Practical Tips for Consistent Giving
- Automate your tithe. Most churches accept ACH transfers or online giving through platforms like Pushpay or Tithe.ly. Setting up a recurring transfer tied to your pay date removes decision fatigue and keeps your local church tithe consistent.
- Budget from your giving line first. Financial stewardship teachers often recommend treating your tithe as a fixed expense — the first line item in your budget — rather than whatever is left at month end. Using your yearly tithe figure from the calculator helps set that annual budget target.
- Review annually. When your income changes — raise, new job, spouse returning to work — revisit the calculator with the updated figure. Church giving should reflect current income, not a figure set years ago.
- Keep records for your own tracking. While tithing to a registered 501(c)(3) church may be tax-deductible in the United States (consult a tax professional for your specific situation), many people track their giving independently of tax motivations — simply as a record of their stewardship commitment.

Frequently Asked Questions
Multiply your income per pay period by your tithe percentage. For a 10% tithe on a $4,000 monthly salary, the calculation is $4,000 × 0.10 = $400 per month. Enter those same figures in the calculator above and it will handle the math instantly.
Tithe Amount = Income × Tithe Rate. The traditional rate is 10% (expressed as 0.10 in the formula), based on the Old Testament standard of giving a tenth of one's increase.
This is a personal and doctrinal decision rather than a mandated rule. Tithing on gross income applies the percentage before taxes are removed, following the firstfruits principle. Tithing on net income uses take-home pay. Both approaches are widely practiced; what matters most is making a deliberate, consistent choice.
For a monthly tithe, divide your annual gross (or net) income by 12, then multiply by your tithe rate. For a weekly tithe, divide the annual figure by 52 and multiply by the rate. The calculator automates this — simply select your pay frequency and enter your per-period income.
A tithe is a structured, recurring gift — typically 10% of income — given as a proportional commitment. An offering is any additional, voluntary gift given beyond the tithe, often in response to a specific need, campaign, or personal prompting.
Many believers apply their tithe rate to bonuses and commission income the same way they do to regular wages, treating all earned income consistently. Others give an offering on irregular income rather than a strict tithe. There is no universal rule; the decision rests on personal conviction and denominational guidance.
The primary Old Testament reference is Malachi 3:10, which instructs bringing "the whole tithe into the storehouse." Leviticus 27:30 describes the tithe as "holy to the Lord." In the New Testament, Jesus affirms tithing in Matthew 23:23 while emphasizing that justice and mercy matter alongside it. The Apostle Paul in 2 Corinthians 9:7 encourages giving that is intentional and cheerful rather than compelled.
The tool multiplies your income per period by your chosen tithe percentage. Select your income basis (gross or net), your pay frequency, enter the income amount, optionally add extra income sources, set the tithe percentage slider, and click "Calculate My Tithe." Results are instant and require no login or personal data.
