Three ways couples split rent

  • Equal shares

    Half each. It is the simplest, and it works well when you earn about the same and have similar rooms.

  • In proportion to income

    Each of you pays the share of the total that matches your take-home pay, so £2,800 and £1,800 a month share 61% and 39%.

  • In proportion to room size

    Each of you pays by the size of your room, so the person with the bigger room pays a little more.

Questions people ask

How do couples split rent fairly?

There is no single right answer. Some couples pay half each, some pay in proportion to what they earn, and some pay by the size of their room. This calculator shows all three side by side so you can see the difference in pounds each month, then choose what feels fair to both of you.

Should we split rent equally or by income?

Equal shares are simple and easy to explain. Splitting by income means the person who earns less pays less, and the person who earns more pays more, but each keeps a similar share of their pay. Try both and talk about which one suits the two of you.

How does splitting by room size work?

Each of you pays in proportion to the size of your room. If one bedroom is 16 square metres and the other is 12, the shares are 57% and 43%. You can type bedroom sizes, or any numbers that show the shares you have in mind, such as extra weight for an ensuite.

Are bills included in the split?

Yes, if you fill them in. The calculator adds bills to the rent and shares the total the same way. If you would rather split bills equally and rent another way, leave the bills box empty and work them out separately.

What if one of our incomes changes?

Change the number and the shares update straight away. You might agree to look at the split again when one of them changes job, has a pay rise or goes part time, so it keeps feeling fair.
