- Then, choose the tithe percentage you'd like to give (example: 10%)
- Move the decimal of the tithe percentage two spots to the left (example: 10 becomes .10)

Do I pay tithing on gross or net income?
Many people pay tithe on their gross (before-tax) income, which is why our calculator uses gross income.
However, there doesn't seem to be a hard-and-fast rule on how to calculate your tithing.
Ultimately, this choice is up to you. If you find that paying tithes on net (after-tax) income is preferable, go for it.
What is considered a full tithe?
Tithe is typically 10% of your annual gross income.
However, your tithe can be as much or as little as you want. Everyone's financial situation is different and it's up to you to decide how much you're comfortable giving.
For this reason, our tithe calculator lets you choose the percentage you want to give.
According to a study from Subsplash,
77% of regular tithers give between 11% - 20% of their income. However, between 75% and 90% of church members don't pay tithe at all.

How to calculate tithe in retirement?
Many people take different approaches to tithing on retirement income. Here's a few ways you can calculate your retirement tithing:
- Calculate 10% of the fixed income you receive. If you receive Social Security, rental income, a pension, or any other fixed income, you might keep it easy and calculate 10% of that to pay to the church.
- Calculate 10% of your investment income. If your portfolio is generating an income for you via dividends, you might calculate 10% of that as a tithe.
- Calculate 10% of your retirement account distributions. If you receive distributions from a retirement account that you've been paying into, you might tithe 10% of your yearly distribution amount.

Is tithe a charitable donation?
Yes, tithing can count as a charitable donation and is tax deductible.
To deduct your tithing from your taxes, be sure to verify your donation amount with either a bank record or written acknowledgement from your church.
According to H&R Block, if any of your cash donations exceed $250, you must get a receipt from the church. In this case, a bank record won't count as verification.[2]
Bottom Line
Tithing is important to many churches, and it helps fund the work they do in their community. If you decide to tithe, use this calculator to figure out how much you'll give per week, month, and year. And remember, there's no "right" way to tithe - anything you decide to give is surely appreciated.
