How to use this calculator
Open the short walkthrough for choosing and checking inputs.
Equal mode assigns the same weight to every included person. Income and room-size modes divide rent in proportion to the entered weights, then use a largest-remainder cent allocation so every share adds exactly to rent.

Before acting
Assumptions to check
Review the real-world details that can change the estimate.
The key inputs are Total monthly rent, Split method, People sharing the rent, Person 1 income or room-size weight, Person 2 income or room-size weight. Equal mode ignores entered weights; income and room-size modes use proportional weights and a largest-remainder cent allocation so the included shares always add exactly to rent.

When to round up
Agree on the method and inputs before using the result. This version divides rent only; it does not automatically value shared rooms, couples, bathrooms, amenities, utilities, lease liability, or legal fairness.
When to use this calculator
- Answering the specific rent split question with your own inputs
- Testing how one entered assumption changes the result
- Preparing a documented planning scenario before checking current quotes, contracts, rules, or nonfinancial tradeoffs
Tips for better estimates
- Replace every sample value with a current amount that uses the same unit and time period as the field label.
- Change one assumption at a time so the effect on the result remains clear.
- Confirm contracts, quotes, policies, eligibility, safety limits, and nonfinancial tradeoffs outside the arithmetic.
How this calculator is reviewed
This page is checked for inputs, formulas, examples, assumptions, topic fit, and related links. For this calculator, the review also covers total rent, included occupants, the agreed split method, entered weights, exact-cent reconciliation, shared-room tradeoffs, and lease responsibility.
The sample result is covered by automated tests, and the page links to related calculators and, where available, supporting guides so readers can check the assumptions before acting. If a formula, label, or assumption looks off, send the page URL and your inputs through the contact page.
Sources to verify assumptions
Use these official and consumer-reference sources to check the terms and rules behind the inputs. The calculator result still depends on the values and method you select.
Worked example
Example inputs: Total monthly rent: $2500; Split method: Proportional to income; People sharing the rent: 3 people; Person 1 income or room-size weight: 3000; Person 2 income or room-size weight: 4000; Person 3 income or room-size weight: 5000. With those values, the calculator returns $2,500.00 rent allocated by income. The entered rent is divided among 3 people using income. Shares are reconciled to the cent so they add back to the full rent.
Example scenarios
- A $2,500 rent split by entered incomes of $3,000, $4,000, and $5,000 assigns exact cent-reconciled shares rather than leaving a rounding remainder.
- Run equal and room-size modes separately to make the tradeoff visible before roommates agree.
- The private allocation does not change the lease's legal responsibility or automatically include utilities and shared fees.

FAQs
Rent Split Calculator questions
Does this calculator decide the fairest split?
No. It makes one chosen method transparent. Roommates still need to agree on whether equal shares, income, room size, or another arrangement fits their household.
Why do some shares differ by one cent?
When rent cannot be divided evenly to the cent, the calculator assigns leftover cents deterministically so the shares reconcile exactly to the rent.
Can I use income and room size together?
Not in the same calculation. Run both methods and compare them, or agree on custom percentages outside this calculator.
Does this change what each tenant owes under the lease?
No. The lease and applicable law control legal responsibility. This is a private planning allocation only.
