Roommate Chore Fairness Calculator
Turn chore hours into money, compare them with who paid for what, and see exactly who owes whom so your household can settle up without an argument.
Is your household fair?
Add each roommate's chores and payments. The calculator compares everyone with the average.
Regular chores are things like dishes, tidying, and cooking. Unpleasant chores are the ones nobody wants, such as the bathroom, trash, and deep cleaning. Costs paid are shared bills and supplies each person covered this month.
To even things out, $230.00 per month needs to move between roommates. A score of 100 means everyone carries an equal load.

Quick examples
What is a roommate chore fairness calculator?
A roommate chore fairness calculator compares what each person in a shared home contributes, in both time and money, and shows whether the load is balanced. Most roommate disagreements are not about a single dirty dish. They come from a feeling that one person is doing more, and that feeling is hard to settle without numbers.
This calculator turns chore hours into a dollar amount using a shared time value, adds the shared costs each person paid, and compares everyone with the household average. The result is a fairness score, a list of who owes whom, and a plain summary you can send to your group chat.
How the time value split works
Each person's chore time is weighted first. Regular hours count once, and hours spent on unpleasant chores count more, based on the weight you choose. That weighted time is multiplied by your hourly value and by about 4.33 weeks in a month to get a monthly time value.
Then the calculator compares each person with the average. Someone above the average on time or on money paid is owed the difference, and someone below it owes.
Why unpleasant chores should count for more
An hour spent scrubbing a shower is not the same as an hour spent wiping a counter. When a household treats them the same, the person who reliably takes the worst jobs ends up quietly doing more for the same credit. A weight above 1 corrects that without forcing anyone to argue about which chores are worse.
Try weights between 1.25 and 2. If your house has one universally hated job, such as the bathroom, a higher weight makes sense. If everyone shares the hard jobs evenly, set the weight to 1 and the result will barely change.
Splitting costs and chores together
Chores and costs are two ways of contributing to the same home, so it helps to see them on one scale. A roommate who pays the internet and groceries is carrying part of the load even if they clean less. Another who barely pays but cleans constantly is doing the same in a different way.
Combining the two means the balance can be settled either way. The person who owes can pay the amount shown, or cover extra chore hours instead. Each roommate's card shows how many weighted hours per week would close their gap.
How to use the results at a house meeting
Agree on the hourly value and the unpleasant chore weight before anyone enters numbers, so the inputs feel neutral. Then have everyone add their own hours and payments, or copy the link into your group chat so each person can check the figures. Numbers that everyone helped enter are much easier to accept than numbers one person built alone.
Settle monthly, in cash or through a payment app, and start the next month fresh. If a balance keeps pointing at the same person, treat it as a signal that the chore plan needs a change rather than a reason for blame. For students, it also helps to lower chore hours during exam periods and revisit the split when schedules change at the start of a term.
A full worked example
Three roommates set a time value of 15 dollars an hour and count unpleasant chores at 1.5 times. Alex does 3 regular hours and 0.5 unpleasant hours a week, so their weighted time is 3.75 hours. Sam does 2 regular hours and 1.5 unpleasant hours, for 4.25 weighted hours. Jordan does 1 regular hour, for 1.00 weighted hours. The total is 9 weighted hours, so the fair share is 3.00 hours each.
At 15 dollars an hour over 4.33 weeks, the household's chore time is worth 585 dollars a month, or 195 dollars each. Alex's time is worth 243.75 dollars, Sam's is 276.25 dollars, and Jordan's is 65 dollars. Shared costs paid this month total 420 dollars, which is 140 dollars each: Alex paid 260, Sam paid 120, and Jordan paid 40.
Alex is 48.75 dollars above average on time and 120 dollars above on costs, so Alex is owed 168.75 dollars. Sam is 81.25 dollars above on time and 20 dollars below on costs, so Sam is owed 61.25 dollars. Jordan is 130 dollars below on time and 100 dollars below on costs, so Jordan owes 230 dollars. Jordan pays Alex 168.75 dollars and Sam 61.25 dollars. The fairness score is 77 out of 100 because 230 dollars of the household's 1,005 dollar total has to move to make it even.
Frequently asked questions
What does time value mean in this calculator?
Time value is the dollar amount you assign to one hour of chore work. The calculator multiplies each person's weekly chore hours by that rate and by the number of weeks in a month, which turns time spent on chores into a monthly amount that can be compared with money spent on shared costs. It lets a roommate who does more housework get credit against someone who simply pays more of the bills.
What hourly rate should we use?
Pick one shared rate for everyone, since the goal is fairness rather than measuring who earns more. A common choice is the going rate for a local cleaner or the local minimum wage. Using a single rate means an hour of dishes from a student on a low income counts the same as an hour from someone with a higher paying job, which keeps the comparison simple and easy to agree on.
Why do unpleasant chores count for more?
Most households have chores that nobody wants, such as cleaning the bathroom, taking out trash, or scrubbing the oven. If every hour counts the same, the person who always takes those jobs is treated the same as someone who does the easy tasks. The unpleasant chore weight multiplies those hours, so 1.5 means an hour of a disliked chore counts as an hour and a half of regular work.
Does the calculator split rent?
It splits the shared costs that roommates pay out of pocket, such as utilities, internet, groceries, cleaning supplies, and household items, by adding up what each person paid and dividing the total equally. It does not set rent shares, because rooms differ in size and price. If your rent is unequal, enter only the shared costs that should be split evenly and leave rent out.
How do we share the results with our roommates?
Use the copy button to grab a short summary you can paste into your group chat, or use the link button to copy a web address that reopens the calculator with your names and numbers already filled in. Everyone can then check the inputs, change anything they disagree with, and see the result update right away.
What if someone cannot do chores for a while?
Life gets in the way, especially during exams, illness, or a busy work stretch. Reduce that person's chore hours for the period, or agree that they cover more of the shared costs instead. The calculator is flexible about how the balance is settled, so a swap of money for time works just as well as an even split of hours.
How often should we settle up?
Monthly works well for most households because bills and chores follow a monthly rhythm. Track hours loosely during the month, pay the balance shown here at the end, and start fresh. If one person is far behind, a short check in every week or two avoids a large balance building up and makes the conversation less awkward.
Is a fair split the same as an equal split?
No. An equal split gives everyone the same share regardless of what they actually contribute. A fair split compares what each person put in, in time and money, against the household average. If everyone does the same amount, the two match. When contributions differ, this calculator shows the difference so it can be evened out with a payment or a swap of chores.
