To split bills as a couple, sort shared costs into fixed, variable and occasional, pick one rule for each (equal, by income percent, or one partner covers it), decide how money moves, and settle up on a set day. In the worked month below, $2,400 of shared costs ends in one $440 transfer.

Key points:
- Sort shared costs into fixed monthly, variable monthly and occasional, then pick one rule per bucket.
- One possible mix is rent by income and groceries equal. At take-homes of $4,500 and $3,000, income shares are 60 and 40 percent.
- Fixed bills can repeat on a schedule. Variable bills are recorded as they come, then one settle-up evens everything out.
- In EvenOut, a one-on-one friend page needs no group. It supports equal and percent splits, a monthly Repeat and one Settle up.

## Step 1: sort your shared costs into three buckets

Start by listing everything you both pay for and sorting it by how it behaves. Rules that work for rent do not always work for groceries.

| Bucket | Examples | What to watch |
|---|---|---|
| Fixed monthly | Rent, internet, a phone plan | Same amount on the same date, so it can run on a schedule |
| Variable monthly | Electric and gas, groceries | The amount changes, so each one gets recorded |
| Occasional | Trips, gifts, a sofa | Rare, so agree the rule before the money is spent |

Personal spending stays outside the buckets. Only costs you both agree are shared go on the list.

## Step 2: pick one rule for each bucket

Each bucket gets one rule, and there are three to choose from.

- **Equal.** Each partner pays half. A $1,500 rent is $750 each.
- **By income percent.** Each pays their share of combined take-home pay. At take-homes of $4,500 and $3,000, the shares are $4,500 ÷ $7,500 = 60% and 40%, so the same rent is $900 and $600. The [split bills based on income guide](https://www.evenoutapp.com/guides/split-bills-based-on-income) covers the formula.
- **One partner covers it.** One of you pays a bill outright, and the other covers a different one of similar size.

Mixing rules is fine. One mix is fixed costs by income and variable costs equal. The point is that each bucket has one rule, so nobody has to decide again when a bill arrives.

## Step 3: choose how the money moves

There are three common patterns, and each one asks for different bookkeeping.

1. **One partner pays every bill** and the other sends their share on a set date. You record each expense, and the second partner sends one transfer.
2. **Each partner pays certain bills.** One of you pays the rent and the other pays utilities and groceries. You record each expense, and one transfer evens up the difference at the end.
3. **A joint account pays the bills.** Both of you fund it on payday. You record nothing between you, but you do need to agree the transfer amounts. [Joint account or separate accounts](https://www.evenoutapp.com/guides/joint-account-vs-separate-accounts) compares the monthly mechanics.

## Step 4: fix a settle-up day and put fixed bills on repeat

Pick one day a month to even up, for example the 1st. Between those days, record variable costs as they happen. Fixed bills do not need to be typed in again each month, because an app with repeating expenses can add them for you. That leaves only the variable costs and the one-offs to enter by hand.

## Step 5: re-check the rule when income or housing changes

A split that fit last year can stop fitting. Re-run the numbers when either take-home changes or when your housing costs change. If the lower earner's take-home rises from $3,000 to $4,500, the income split becomes 50/50 and the $1,500 rent is $750 each. Put a recurring date in your calendar, such as every January, to look at it.

## A worked month: $2,400 of shared costs

Say Sam takes home $4,500 and Jo takes home $3,000. They split fixed costs 60/40 and everything else equally. Sam paid the rent and some groceries. Jo paid the rest.

| Cost | Paid by | Rule | Sam / Jo |
|---|---|---|---|
| Rent, $1,500 | Sam | 60/40 | $900 / $600 |
| Internet, $100 | Jo | 60/40 | $60 / $40 |
| Electric and gas, $200 | Jo | Equal | $100 / $100 |
| Groceries, $300 | Sam | Equal | $150 / $150 |
| Groceries, $200 | Jo | Equal | $100 / $100 |
| Wedding gift, $100 | Jo | Equal | $50 / $50 |

The costs add to $2,400. Sam's shares add to $1,360 and Jo's to $1,040. Sam paid $1,500 + $300 = $1,800, so Sam is owed $440 ($1,800 minus $1,360). Jo paid $100 + $200 + $200 + $100 = $600, so Jo owes $440 ($1,040 minus $600). One transfer of $440 from Jo to Sam clears the month.

## How do you set this up in EvenOut?

EvenOut's friend page is a ledger for two, so you do not need a group.

1. **Connect with your partner.** On the Friends tab, tap "Add a friend" and have them scan your code or open your invite link.
2. **Add an expense.** Open their page and tap "Add expense". Type the amount and what it was for, then choose "Paid by you" or "Paid by Jo".
3. **Pick the split.** Tap the split chip, which reads "Split equally" by default. For an income split, choose "Percent" and type 60 and 40. The pill reads "Adds up to 100%" when it works.
4. **Put fixed bills on repeat.** Under "Photo, repeat, pending or note", tap "Repeat" and choose "Monthly". EvenOut adds each later bill itself with the same payer and split, so it suits rent and internet rather than bills that change.
5. **Settle up.** On the settle-up day, open the friend page and tap "Settle up". It records the full balance, which here is $440.

The friend page's "…" menu has "Charts" ("Where your shared money goes") and "Remind Jo". EvenOut has no daily expense limit on its free plan, and repeating expenses and charts are free.

## Frequently asked questions

### How often should a couple settle up?

Once a month on a fixed date is a simple rhythm, because the fixed bills and the variable ones have all landed by then. Settling after every purchase creates many small transfers for the same net amount.

### Do we need to track every grocery trip?

Only if the groceries are split. If you cover groceries one month and your partner covers them the next, the amounts roughly cancel and you can skip the receipts. If one of you does most of the shopping, record each trip so the balance stays honest.

### Can we split a bill unequally just once, like a gift?

Yes. The split is chosen per expense, so a one-off can be equal while rent runs by percent. In EvenOut you can also pick Exact amounts for a one-off.

### What if one of us stops earning for a while?

Re-run the income percentages with the new take-home figures, then set a date to look again. If one take-home drops to $0, the percent split puts the whole bill on the other person, so you may want a different rule for that stretch.
