How It Works

Enter the bill total

Type the full amount to split — rent, groceries, or any shared expense.

Add each person’s monthly income

Add a row per person and enter their monthly take-home income. Add as many people as you need.

Split proportionally

Each person’s share equals their fraction of the combined income. Earn twice as much, pay twice as much.

Worked Example

Alex and Sam split $1,500 of rent. Alex earns $4,000/month and Sam earns $2,000/month, so the combined income is $6,000. Alex’s share is 4,000 ÷ 6,000 = 66.67% and Sam’s is 33.33%:

Person	Monthly income	Share
Alex	$4,000	$1,000.00 (66.67%)
Sam	$2,000	$500.00 (33.33%)
Total	$6,000 combined	$1,500.00

Frequently Asked Questions

Should I use gross or net income?

Net take-home pay is fairer, since it reflects what each person actually has available to spend.

What if someone has no income right now?

Give them an income of 0. If everyone’s income is 0, the calculator falls back to an equal split.

Is a proportional split fair for couples?

Many couples find it fairer than 50/50 when earnings differ. Agree on the approach first, then use the numbers.

Is my income data sent to a server?

No. The calculation runs entirely in your browser. Nothing you enter is uploaded, stored, or shared.
