Put the bills everyone uses into one shared pool, give each bill one rule, and settle once a month. Housing can follow income, utilities and internet can be equal, and groceries can follow days at home. For four adults with $3,255 of bills, that gives monthly shares from $573.75 to $1,053.75.

Key points:
- Pool only what everyone uses and the household is billed for. Personal phones, personal subscriptions and one person's car stay with that person.
- Give each bill one rule: income for housing, equal for utilities and internet, days at home for groceries.
- In the example, four adults owe $1,053.75, $813.75, $573.75 and $813.75 on $3,255.00 of bills.
- Spread the bills across different names and settle once a month, so nobody fronts everything. Here three transfers close the month.

## Which bills belong in the shared pool?

A bill goes in the pool when everyone in the home uses it and the household is billed for it, not one person. That usually means the rent or mortgage payment, electricity, gas, water, trash, internet, shared groceries and cleaning supplies. Each person's phone, personal subscriptions and a car loan stay with their owner.

This page is for adults who share a home, in any mix: partners, siblings, a parent and an adult child, or roommates. Say Rosa and her partner Jack live with Rosa's brother Tomas and their mother Lena. Take-home pay is $3,600 for Rosa, $2,800 for Jack, $2,400 for Tomas and $1,200 for Lena, which is $10,000 in total.

## Which rule goes with which bill?

Use one rule per bill, chosen for how the bill behaves. The household's bills come to $3,255.00 a month.

| Bill | Monthly cost | Rule | Why |
|---|---|---|---|
| Housing | $2,000.00 | By take-home pay | The largest bill, and incomes differ |
| Utilities | $310.00 | Equal | Used by the whole home |
| Internet | $65.00 | Equal | Everyone uses it |
| Groceries | $880.00 | By days at home | Jack is away 10 days a month |

## What does each person owe?

Work each rule out once, then add across.

- **Housing by income.** Rosa pays 36% of $2,000, which is $720.00. Tomas pays 24%, $480.00. Lena pays 12%, $240.00. Jack pays 28%, $560.00. The method is in [how to split bills based on income](https://www.evenoutapp.com/guides/split-bills-based-on-income).
- **Utilities and internet equally.** $310.00 ÷ 4 = $77.50 and $65.00 ÷ 4 = $16.25, which is $93.75 each.
- **Groceries by days at home.** Rosa, Tomas and Lena are home 30 days and Jack 20, so there are 110 person-days. $880.00 ÷ 110 = $8.00 a person-day. That is $240.00 each for three people and $160.00 for Jack.

| Person | Housing | Utilities and internet | Groceries | Total |
|---|---|---|---|---|
| Rosa | $720.00 | $93.75 | $240.00 | $1,053.75 |
| Tomas | $480.00 | $93.75 | $240.00 | $813.75 |
| Lena | $240.00 | $93.75 | $240.00 | $573.75 |
| Jack | $560.00 | $93.75 | $160.00 | $813.75 |

The totals add to $3,255.00. Check each total against take-home before you accept it. Lena's $573.75 is 47.8% of her $1,200, and Rosa's $1,053.75 is 29.3% of $3,600. That gap comes from the equal and per-day bills. If it is too steep, put every bill on the income rule, which makes each person pay 32.55% of their take-home.

## Who pays which bill?

Spread the bills across different people and settle once a month. Say Rosa pays the housing, Tomas pays utilities and internet, Jack pays the groceries, and Lena pays nothing up front. Comparing what each person paid with what they owe gives the settle-up.

| Person | Paid up front | Share of the bills | Net |
|---|---|---|---|
| Rosa | $2,000.00 | $1,053.75 | Owed $946.25 |
| Tomas | $375.00 | $813.75 | Owes $438.75 |
| Lena | $0.00 | $573.75 | Owes $573.75 |
| Jack | $880.00 | $813.75 | Owed $66.25 |

Three transfers close the month. Tomas pays Rosa $438.75, Lena pays Rosa $507.50 and Lena pays Jack $66.25. Rosa receives $946.25 and Jack receives $66.25, while Tomas sends $438.75 and Lena sends $573.75, so every net balance reaches zero.

## When should you re-run the numbers?

Re-run them when someone moves in or out, when anyone's income changes by a lot, and when a bill changes by more than you would shrug off. Add a reminder for the month the lease or the internet plan renews. The days at home are the one input that changes every month, so count them from a shared calendar or ask each person for their number on the settle-up day.

## How do you set it up in EvenOut?

Make a "Household" group ("Rent and bills") and add the other three. Then add each bill as an expense with "Paid by" set to whoever paid it.

1. **Housing.** Type $2,000.00, choose the split, open "Percent" and enter 36, 24, 12 and 28. The pill reads "Adds up to 100%".
2. **Utilities and internet.** Leave "Split equally".
3. **Groceries.** Choose "Shares" and type 30, 30, 30 and 20. The sheet reads "110 shares · $8.00 a share".

Under "Photo, repeat, pending or note", "Repeat" set to "Monthly" adds the same expense each month. It suits housing and internet but not utilities, which change every month. "Simplify debts" is on by default, so EvenOut proposes the fewest payments. Record each transfer with "Settle up". EvenOut records the payment and you send the money yourselves. A printable version of the bill list is in the [household bills spreadsheet](https://www.evenoutapp.com/templates/household-bills-tracker).

## What should you do next?

Write down the bill list, the rule for each bill, and the percentages, then send it to the household for a yes. Try the first month, then compare the amounts with take-home. The [roommate expense calculator](https://www.evenoutapp.com/tools/roommate-expense-calculator) splits rent by weights, so take-home pay works as the weights, and shares the other costs equally.

## Frequently asked questions

### Is an equal split of household bills fair?

It is equal in dollars and uneven in effect. On the $3,255 pool an equal split is $813.75 each, which is 22.6% of Rosa's $3,600 take-home and 67.8% of Lena's $1,200. Check each person's amount against their take-home before settling on equal.

### What if someone is away for most of the month?

Weight groceries and other usage-based costs by the days each person is home. Keep fixed bills such as housing and internet unchanged, because the bill does not shrink when someone is away. In the example, 10 days away takes Jack's groceries from the $220.00 an equal split would charge to $160.00.

### What if someone would rather not share their income?

Agree on percentages instead of incomes. Saying 36, 24, 12 and 28 percent states the split without anyone's pay. The percentages still show the ratios between people, so if that is too much, split equally or agree dollar amounts directly.

### Whose name should the bills be in?

Spread them across the household, so no one person carries every account or fronts every payment. The name on a bill is who the company deals with. Your split is a separate agreement about who repays whom, and a monthly settle up evens it out.
