Tithing — giving one-tenth of your income to your church or ministry — is a deeply held practice for millions of Christians across Africa and worldwide. While the principle is straightforward, the practical calculation raises questions that many believers wrestle with. Should you tithe on your gross salary or your take-home pay? What about bonuses, gifts, and side income? And how do mandatory deductions like tax, pension, and NHF factor into the equation?

Our free Tithe Calculator takes the guesswork out of the process. Enter your income details, choose whether to calculate on gross or net, and the tool gives you an exact tithe amount along with a breakdown that accounts for your specific deductions and additional income sources.

What Is a Tithe?

A tithe is 10% of your income given to God through your local church or designated ministry. The word comes from the Old English for “tenth.” The practice has deep roots in both the Old and New Testaments, with the Old Testament establishing the principle through passages about giving the first fruits and a tenth of produce and livestock. The New Testament shifts emphasis toward generosity and cheerful giving, with different denominations interpreting the exact expectations differently.

Regardless of theological nuance, the practical question remains the same: 10% of what exactly?

Gross Income vs Net Income: The Core Debate

The Case for Tithing on Gross Income

Many believers hold that tithing on gross income (your full salary before any deductions) is the proper approach. The reasoning is rooted in the first-fruits principle — giving God the first and best portion of what you earn, before anything else is taken out. Under this view, taxes, pension contributions, and other deductions are obligations that come after your obligation to God.

For a Nigerian salary earner with a gross monthly income of N500,000, tithing on gross means giving N50,000 each month, regardless of the fact that PAYE tax, pension, NHF, and other deductions may reduce your take-home pay to N350,000 or less.

The Case for Tithing on Net Income

Others argue that net income (your actual take-home pay after mandatory deductions) is the more practical and fair basis for tithing. The reasoning is straightforward: you never actually receive the money deducted for taxes and pension. It goes directly from your employer to the government and pension fund administrators. How can you give what you never possessed?

Using the same example, tithing on net income of N350,000 means giving N35,000 — a difference of N15,000 per month or N180,000 per year compared to tithing on gross.

Finding Your Conviction

There is no universally agreed-upon answer across all Christian denominations. Different churches teach different positions, and many leave it to individual conviction. What matters is consistency and sincerity in your giving. Whether you choose gross or net, committing to a clear approach and following through faithfully is more important than the specific calculation method.

To understand exactly how your salary breaks down between gross and net, use our salary after tax guide alongside the tithe calculator.

Calculating Tithe on a Nigerian Salary

Let us walk through a practical example for a Nigerian salary earner on a gross monthly salary of N600,000.

Deductions

Total deductions: N143,000

Net salary: N457,000

Tithe Amounts

The monthly difference is N14,300, which over a year amounts to N171,600. This is a significant sum, and it is why the gross-vs-net question matters practically, not just theologically. You can model your own salary deductions with our PAYE tax guide.

What About Other Income Sources?

Most tithers do not earn only a salary. Additional income sources raise their own questions:

Business Profits

For business owners and entrepreneurs, tithing on revenue would be unsustainable — you would be tithing on money that belongs to suppliers, employees, and landlords. Most financial counsellors and pastors recommend tithing on profit (revenue minus business expenses), which is the true income equivalent for a business person.

Bonuses and 13th Month

If you receive annual bonuses or a 13th-month salary, applying the same tithe percentage to these amounts is the most consistent approach. A N500,000 annual bonus would generate a N50,000 tithe if you tithe on gross bonus income.

Financial Gifts

Some tithers include monetary gifts from family and friends as titheable income. Others view gifts as a separate category. There is no consensus on this point — it depends on your personal conviction and your church’s teaching.

Investment Returns

Interest on savings, dividends from stocks, and profits from property sales are all forms of income. Many tithers include investment returns in their tithe calculation, particularly when the returns are realised (actually received as cash). Unrealised gains (paper profits on investments you have not sold) are generally not included.

Side Hustles and Freelance Work

Freelance income, gig work, and side businesses follow the same logic as primary business income. Tithe on the net profit after deducting legitimate business expenses. Our freelance pricing guide can help you think about structuring your side income.

Tithing on Irregular Income

Many Africans do not earn a fixed monthly salary. Farmers, traders, artisans, and gig workers have income that fluctuates week to week and season to season. For irregular earners, two approaches work well:

  1. Tithe as you earn: Each time you receive income (a sale, a payment, a harvest), immediately set aside 10% before spending any of it. This is the simplest approach and aligns with the first-fruits principle.
  2. Monthly accounting: Track your total income for the month, subtract business expenses, and tithe on the net figure at month end. This works better for people who prefer to see the full picture before calculating.

Practical Tips for Consistent Tithing

1. Automate Where Possible

If your church accepts bank transfers or mobile money, set up a standing order for your tithe amount on your payday. Automation removes the temptation to skip or reduce your tithe when money feels tight.

2. Keep Records

Track your tithes alongside your income in a simple spreadsheet or notebook. This helps you stay accountable to your commitment and makes year-end reviews straightforward.

3. Budget Your Tithe First

In personal budgeting, treat your tithe as a non-negotiable first expense rather than something you give from whatever is left over. This aligns with the first-fruits principle regardless of whether you calculate on gross or net income.

4. Communicate With Your Spouse

In married households, tithing decisions affect the entire family budget. Ensure both partners agree on the approach — gross vs net, which income sources to include, and how the tithe is paid.

Tithing and Financial Responsibility

A question that comes up frequently: should you tithe when you are in debt, struggling financially, or unable to meet basic needs? This is deeply personal, and different pastors and financial advisers give different counsel.

What is broadly agreed is that tithing should not come at the expense of feeding your family or paying for essential medicine. Equally, financial difficulty is not automatically a reason to stop giving entirely. Many faith communities offer flexible guidance, encouraging members to give what they can while working toward financial stability.

Building a solid financial foundation supports consistent giving over the long term. Our Savings Goal Planner can help you balance tithing commitments with emergency fund building and debt repayment.

Frequently Asked Questions

Should I tithe on gross or net income?

This is a matter of personal conviction. Tithing on gross income honours the first-fruits principle of giving before anything else is deducted. Tithing on net income is practical since you never receive the amounts deducted for tax and pension. Both approaches are valid, and the most important thing is consistency and sincerity.

How do I calculate 10% tithe on my salary?

Multiply your chosen income figure (gross or net) by 0.10. For example, if your monthly net salary is N350,000, your tithe would be N35,000. Use our Tithe Calculator for an instant breakdown.

Do I tithe on bonuses, gifts, and other income?

Many tithers include all income sources: salary, bonuses, business profits, financial gifts, and investment returns. Others tithe only on regular income. The decision depends on your personal conviction and your church’s teaching.

Is tithing compulsory for Christians?

Views differ across denominations. Many churches teach tithing as an expected practice. Others view it as a guideline, emphasising generous and cheerful giving over a fixed percentage. The New Testament emphasises giving from the heart rather than prescribing a specific amount.

Can I split my tithe between multiple churches or ministries?

This depends on your church’s teaching. Some denominations teach that the full tithe should go to your local church, with additional offerings directed elsewhere. Others allow tithers to distribute their 10% across multiple ministries. Consult your church leadership for guidance.
