How to use this tithe calculator
- Enter your income for one pay period (or annual).
- Pick your frequency — weekly, bi-weekly, semi-monthly, monthly, or annual. The calculator shows both the per-period and annual totals.
- Choose gross or net. Gross income honors the firstfruits principle (Proverbs 3:9). Net is also faithful — Scripture doesn't bind you to one base.
- Adjust the tithe percentage (10% by default) and add an optional freewill offering on top.
What does the Bible say about tithing?
The word tithe simply means "a tenth." Tithing predates the Mosaic Law: Abraham gave a tenth of the spoils to Melchizedek (Genesis 14:20) and Jacob vowed a tenth to God at Bethel (Genesis 28:22). Under the Law, Israel tithed crops, herds, and produce as worship (Leviticus 27:30; Deuteronomy 14:22).
The famous tithing passage is Malachi 3:10 — "Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this." In the New Testament, Jesus commends tithing without abolishing it (Matthew 23:23), and Paul urges proportional, cheerful, weekly giving (1 Corinthians 16:2; 2 Corinthians 9:7).
Gross vs net: which should you tithe on?
Scripture doesn't specify a tax line. The principle that decides it is firstfruits — the first and best portion belongs to God (Proverbs 3:9–10; Exodus 23:19). Most teachers across traditions recommend tithing on gross income for that reason: you give from the top, before taxes and deductions take their share.
That said, tithing on net is not unfaithful. What Scripture cares about is a heart that gives cheerfully, generously, and consistently — not the spreadsheet math.

Frequently asked questions
Does the New Testament command tithing?
The New Testament never re-issues the 10% command, but it never abolishes the principle either. Jesus affirmed tithing in Matthew 23:23 ('these you ought to have done'), and Paul commands proportional, cheerful, regular giving in 1 Corinthians 16:2 and 2 Corinthians 9:7. Most evangelical churches teach 10% as the wise minimum baseline of New Covenant generosity.
Can I tithe to causes besides my local church?
Malachi 3:10 names 'the storehouse' — historically the local worshiping community where you are fed. Most teachers urge the tithe to go to your local church first, with freewill offerings on top going to missions, the poor, or parachurch ministries. Solomon Wealth Code follows that pattern in-app.
Should I tithe on my tax refund or bonus?
A refund is your own withheld income returning to you. If you tithed on gross income, you have already tithed on it. A bonus, however, is new income — most Christians tithe on bonuses as firstfruits when received (Proverbs 3:9).
Is it wrong to tithe with a credit card?
Romans 13:8 warns against owing anyone anything. If you pay the balance in full every month, a card simply changes the rails. If tithing pushes you into revolving debt, give what you can in cash and use our Debt Snowball Calculator to free up margin so generosity can rise.
