A tithe is a portion of income given to a church or charity, traditionally one tenth, which is 10%.

Do I tithe on gross or net income?

It is a personal choice: some tithe on gross income (before tax) and others on net (after tax). This tool supports both — pick the basis that fits your conviction.

Is my income kept private?

Yes: every calculation runs locally in your browser and nothing is sent anywhere.

How do I calculate a 10% tithe?

Multiply your chosen income by 0.10. For example, a 10% tithe on $3,000 is $300, leaving $2,700.

Can I use a rate other than 10%?

Yes. The rate field is editable, so you can enter any percentage — for example 5% for a partial pledge or a higher figure for a larger gift.

What is the difference between tithe and offering?

A tithe is traditionally the fixed tenth of income, while an offering is any additional voluntary gift on top. This calculator handles the percentage-based tithe; add offerings separately.

Does the rate change the remaining amount?

Yes. The remaining figure is your income minus the tithe, so a higher rate gives a larger tithe and a smaller remainder.

Tithe calculator

This calculator works out a tithe — traditionally a tenth of income given to a church or charity — and shows what remains afterward. It supports tithing on either gross or net income and any rate you choose, so it fits different convictions and giving plans.

How it works

The maths is a simple percentage of your chosen income basis:

tithe     = income × rate / 100
remaining = income − tithe

You select whether income is gross (before tax) or net (after tax) — that choice is yours; the calculation is identical either way. The rate defaults to the traditional 10% but can be set to any value. Results are rounded to two decimal places.

Example

On a monthly income of $3,000 at the traditional 10% rate, the tithe is 3000 × 0.10 = $300.00, leaving $2,700.00. Change the rate to 5% and the tithe becomes $150.00, leaving $2,850.00.

Income	Rate	Tithe	Remaining
$2,000	10%	$200.00	$1,800.00
$3,000	10%	$300.00	$2,700.00
$5,000	10%	$500.00	$4,500.00
