Tithe Calculator Nigeria – Work Out Your 10% Tithe (Gross or Net)

Tithing is one of the most widely practised forms of giving among Christians in Nigeria, and the tithe calculator on this page exists to make one part of that practice simple: the arithmetic. Enter a salary, business profit, or any other income figure, choose whether you want to work from your gross pay or your net (take-home) pay, and the tool instantly shows what a traditional ten percent tithe looks like in naira, both as a monthly figure and an annual one. Nothing about the calculation is complicated, but doing it by hand every payday, especially when there are multiple income streams or deductions to account for, gets tedious. That is the gap this tool fills.

The ten percent figure itself comes from a long-standing tradition rooted in the Old Testament, where tithing was practised as giving a tenth of one's produce or income, generally understood in Christian teaching as an act of worship and provision for religious and community life. It is important to be clear from the outset that tithing in Nigeria today is entirely voluntary. No federal or state law compels an individual to pay a tithe, and no statute prescribes how it should be calculated. Whether you tithe on your gross salary or on what lands in your account after deductions is a matter of personal conviction, and different pastors, denominations, and individuals land in different places on the question. This calculator supports both approaches so you can see the numbers either way and decide what fits your own understanding.

A question that comes up constantly among salaried Nigerian workers is whether tithe should be computed before or after statutory deductions such as Pay As You Earn (PAYE) tax and pension contributions. There is no official position on this because, again, no law governs the practice. Some people reason that since PAYE and the mandatory eight percent employee pension contribution under the Pension Reform Act are taken before the money ever reaches them, it makes sense to tithe on what remains, the net pay. Others hold that tithing on the gross figure, the full amount earned before any deduction, better reflects the principle of giving from the "first fruits" of one's labour. This calculator lets you toggle between the two so you can compare both outcomes side by side rather than guessing. When you select the net option, the tool applies a simplified estimate of Nigeria's PAYE bands together with whatever pension and other percentage deductions you specify, purely to give you a reasonable net base figure; it is not a substitute for a full payroll calculation or professional tax advice.

It is worth understanding, separately from your personal tithing decision, how Nigerian tax law treats tithes and offerings once they reach a church, mosque, or similar body. Under the framework that has long applied through the Personal Income Tax Act and the Companies Income Tax Act, the income of an ecclesiastical, charitable, or educational institution of a public character is exempt from tax so long as that income is not derived from a trade or business the institution carries on. In practice, this has meant that offerings, tithes, and similar donations received by a registered church or mosque for its religious and charitable objectives generally fall outside the tax net, while commercial activities a religious body might run on the side, such as renting out property or operating a business, do not enjoy the same exemption. From 1 January 2026, Nigeria's consolidated tax framework, the Nigeria Tax Act and its accompanying administration legislation, carries this same principle forward: properly registered religious and charitable organisations remain exempt on income applied strictly to their approved religious or charitable objectives, provided they keep proper records and separate any commercial income. None of this changes anything about what an individual owes, since tithing has never been a tax obligation for the giver; it only explains why the institution receiving your tithe is generally not taxed on it.

For someone with more than one source of income, perhaps a salary plus a side business or rental income, the calculator allows you to add up to three additional income streams so the tithe is worked out on the combined total rather than on a single figure in isolation. This mirrors how many people in Nigeria actually earn money today, where a formal salary is often supplemented by freelance work, trading, or small enterprise income. The frequency selector then lets you view the resulting tithe as a monthly commitment, an annual total, or a one-time figure for an irregular payment such as a bonus, a harvest sale, or the proceeds from selling an asset.

Ultimately, this tool is a convenience, not a rulebook. It applies a straightforward ten percent calculation to whatever base you choose and presents the result clearly, in naira, using standard Nigerian number formatting so large figures remain easy to read. It does not store your information, does not require an account, and runs entirely in your browser. If you have questions about how much to give, on what basis, or what your faith teaches about giving more broadly, those are questions best directed to your pastor, imam, or religious community, not to a calculator. What this page can do is remove the friction of the arithmetic so you can focus on the decision itself.
