Budgeting as a couple raises a question singles never face: whose money pays for what? The cleanest starting point is to budget the combined household income and agree percentages before arguing about individual purchases.
Enter your combined monthly take-home pay and adjust the split to suit your situation — a household with a mortgage may need more than 50% for needs, while one deep in debt may want more than 20% aimed at repayment.

Frequently asked questions
Should couples budget together or separately?
Both work, but there is usually a shared middle: one joint account for shared needs and goals, plus personal accounts for individual spending. Budget the joint part with this calculator and agree a personal allowance for each person.
How do we split bills if we earn very different amounts?
A proportional split — each person paying the same percentage of their own income, rather than the same dollar amount — keeps things fair without leaving either person short at month end.
Does the 50/30/20 split suit couples?
It is a good default, but households with a mortgage or childcare often exceed 50% on needs. Shift the percentages to match reality, then protect the savings slice as far as you can.
What counts as a need for two people?
Housing, utilities, groceries, transport to work, insurance, minimum debt payments and childcare. Restaurants, streaming subscriptions and hobbies are wants — important, but the first place to trim when money is tight.
How much should a couple save each month?
Twenty percent of combined take-home pay is a solid target, split between an emergency fund covering three to six months of expenses and longer-term goals. If 20% is out of reach, start lower and raise it as debts clear.
