One bill, shared in proportion to what each of you earns.
Enter the amount on the bill, then each person's income below.
Use this when you earn different amounts and are sharing a cost — rent, a household bill, a holiday. The person who earns more pays more, which most people find fairer than a straight 50/50.
Turn this on for a coupon, a member discount or a deal — it comes off the bill first.
Turn this on when the bill shows tax as a separate line, or you want to work it out from a rate.
Turn this on to add a tip — 15, 18 and 20 are one tap.
Each person pays
Enter the bill, then what each person earns. The page turns the incomes into percentages and charges each person that share of the bill. Somebody on 60% of the combined income pays 60% of the bill. The percentages are shown next to each name so you can see the split before you agree to it.
Put both incomes in — monthly or yearly, whichever you like, as long as you use the same unit for both. The bill is then divided in those proportions instead of down the middle. This is the usual approach for couples who keep separate accounts but share rent and household costs.
Same idea, with one income per person. Tap Add a person until everyone is in, then fill in each income. With three or more people the percentages still work the same way — each person pays their own share of the combined income.
If you already know the percentages you want rather than the incomes, set the incomes so they carry the ratio you have in mind — 6000 and 4000 gives 60/40, 7500 and 2500 gives 75/25. The percentages each person ends up paying are printed beside their name.
Proportional means the same thing here: the split follows income. Nothing is rounded to a tidy number, and the shares are rounded to the cent in a way that always adds back up to the exact bill — so you will not be a penny short when you pay.
Use either figure. If you enter yearly salaries, the split is identical to entering the monthly equivalent, because only the ratio between the two incomes matters. Enter both in the same unit and the result is the same either way.
Then the split is 50/50 and the page says so — equal incomes give equal shares. If you would rather split evenly no matter what the incomes are, leave the income boxes empty: with nothing to go on, the page falls back to an equal split.
Fair is a judgement, not a formula. Splitting by income is the common answer when earnings differ a lot, because a 50/50 split of a large shared cost hits the lower earner harder. What this page does is make the proportion visible and exact, so the two of you are deciding about a number you can both see.
