Enter both incomes and your shared monthly bills. Evenly shows each partner's fair share — and what you're each left with to save or spend.
Both left with the same to spend
✓ Both partners left with £1,060.00 — that's the fair split.
Your bills and split carry over — invite your partner and you’re set.
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.
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.
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.
