Split the fixed costs by ownership share and the variable costs by nights stayed, with a peak night counting as 1.5 off-peak nights. In one example with four owners at 40/20/20/20, $15,000 of fixed costs is $6,000, $3,000, $3,000 and $3,000, and $3,600 of cleaning and metered utilities over 120 weighted nights is $30 a night.

Key points:
- Fixed costs such as property tax, insurance, association dues and base utilities follow ownership share. Variable costs follow nights stayed.
- At a peak weight of 1.5, 120 weighted nights sharing $3,600 make an off-peak night $30 and a peak night $45.
- Illustration for four owners at 40/20/20/20: $20,100 a year, from $15,000 fixed, a $1,500 reserve and $3,600 variable.
- A guest night counts as the night of the owner who invited the guest.
- Rental income offsets cost by arithmetic only: $4,000 of rent against $20,100 leaves $16,100 to split.

## Which vacation home costs follow ownership, and which follow nights?

Costs that arrive whether or not anyone stays follow ownership share. Costs that rise with each stay follow nights. A reserve for repairs sits with the first group.

| Cost type | Split by | Typical lines |
| --- | --- | --- |
| Fixed | Ownership share | Property tax, insurance, association dues, base utilities |
| Reserve | Ownership share | Roof, appliances, repairs |
| Variable | Nights stayed, peak nights weighted | Cleaning, consumables, metered utilities |

Every number below is an illustration with round figures, not a typical bill. Replace them with your own.

## How do you split the fixed costs?

Multiply each cost by each owner's share. Say four owners hold 40, 20, 20 and 20 percent. The year's fixed costs are property tax $6,800, insurance $2,400, association dues $3,600 and base utilities $2,200, which is $15,000.

- Owner A, 40 percent: $15,000 × 0.40 = $6,000.
- Owners B, C and D, 20 percent each: $15,000 × 0.20 = $3,000 each.

The four amounts add back to $15,000. Monthly, $15,000 ÷ 12 is $1,250, so the owners pay $500, $250, $250 and $250 a month.

## How big should the reserve be?

Pick a percent of the annual fixed costs and write it down. Say the owners choose 10 percent of the $15,000. That is $1,500 a year, split by ownership share: $600 for owner A and $300 for each of the others. When a repair is paid from the reserve, top the fund back up to the amount you chose.

## How do you split cleaning, supplies and metered utilities by nights?

Count each owner's nights, give peak nights extra weight, and divide the cost by the weighted total. Decide which dates are peak before the season starts. With a peak night counting as 1.5 off-peak nights, the weighted nights are the off-peak nights plus 1.5 times the peak nights.

Say the variable costs are $3,600 for the year.

| Owner | Off-peak nights | Peak nights | Weighted nights | Pays |
| --- | --- | --- | --- | --- |
| A | 24 | 8 | 36 | $1,080 |
| B | 18 | 6 | 27 | $810 |
| C | 30 | 0 | 30 | $900 |
| D | 18 | 6 | 27 | $810 |

The weighted nights add to 120, and $3,600 ÷ 120 is $30. An off-peak night costs $30 and a peak night costs 1.5 × $30, which is $45. Owner A's 36 weighted nights at $30 is $1,080, and the four amounts add back to $3,600.

The nights in the table already include guests. A guest night is counted for the owner who invited the guest, so a friend who stays 4 off-peak nights with owner C is 4 of C's 30.

## What does each owner pay in the year?

Add the fixed share, the reserve and the nights charge.

| Owner | Fixed | Reserve | Nights | Year total |
| --- | --- | --- | --- | --- |
| A | $6,000 | $600 | $1,080 | $7,680 |
| B | $3,000 | $300 | $810 | $4,110 |
| C | $3,000 | $300 | $900 | $4,200 |
| D | $3,000 | $300 | $810 | $4,110 |

The totals add to $20,100, which is $15,000 fixed plus $1,500 reserve plus $3,600 variable.

## How does rental income fit in?

If the owners rent the home out for some weeks, rent received lowers the total to split by plain arithmetic. Say $4,000 comes in. Against $20,100 of costs, $16,100 is left. Share the $4,000 by ownership share, which is $1,600 for owner A and $800 each for B, C and D, and subtract each credit from that owner's year total. A pays $6,080, B pays $3,310, C pays $3,400 and D pays $3,310, which adds to $16,100.

That is arithmetic only. How rental income is taxed or reported is outside this page, so ask an advisor about it.

## How can EvenOut keep the numbers?

Make a group, and choose the Household type, which EvenOut describes as rent and bills. Log each fixed bill with the Percent split and type 40, 20, 20 and 20, and EvenOut shows "Adds up to 100%" when they match. For the nights charge, choose Shares and enter each owner's weighted nights as their shares, which is 36, 27, 30 and 27 in the example.

A bill that comes every month, such as association dues, can be set to repeat monthly and EvenOut adds it for you. Owners who are not on EvenOut can be added with "Add a guest", and the group's charts show spending by category, person and month at no cost. EvenOut records what each owner owes and does not move money, so each owner still pays by their own bank or app.

For a boat owned the same way, see [co-owning a boat](https://www.evenoutapp.com/guides/co-owning-a-boat-costs), which splits fuel by engine hours. If one car is shared instead, [sharing a car with a friend](https://www.evenoutapp.com/guides/sharing-a-car-with-a-friend) covers the same split-by-use idea.

## Frequently asked questions

### What counts as a peak night?

Whatever the owners decide before the season, written down as dates, such as school holidays and summer weekends. The weight is a choice too. A weight of 1 means no weighting, and a higher weight moves more of the cost onto the owners who stay in the busy weeks.

### What if an owner never uses the house?

Fixed costs and the reserve still follow ownership share, because those bills arrive whoever stays. In the example, an owner holding 20 percent with no nights pays $3,000 fixed and $300 reserve, so $3,300 for the year, and nothing toward the nights charge.

### When do owners settle up?

Monthly for fixed bills, which are known in advance, and once after the season for the nights charge. The cost per weighted night is only known when the season's costs and everyone's nights are in, so settling it earlier means guessing.

### Does this cover buying a vacation home with friends?

No. This page covers running costs once the home is owned. Buying, financing and the way ownership is structured each need their own professional advice.
