How to split bills fairly with your partner

There’s no single “correct” way to split household bills — only the way that feels fair to both of you. The three most common approaches are a straight 50/50 split, splitting in proportion to income, and splitting so you’re both left with the same amount of free money afterwards.

What's the fairest way for couples to split bills?

Many couples find splitting bills in proportion to income fairer than 50/50, because it leaves both partners with a similar amount of spending money. The 'fair share' option goes further and splits so both are left with exactly the same after bills.

How do you split bills when one partner earns more?

Use the 'by income' or 'fair share' method. If Partner A earns £2,600 and Partner B earns £1,700, a 50/50 split leaves the lower earner with much less spare cash. Splitting by income keeps it proportional and feels fairer.
