Hannah and Max have always split their money equally even when one has earned considerably more than the other. "We've always wanted to do things 50/50," Max, 31, says. The couple got married after two years together, when Max was earning £70,000 a year working in tech, and Hannah, who works in the charity sector, was earning considerably less. Their salaries go into a joint account and their mortgage, bills, food, petrol and other household costs are paid out of this. They also divide money into different pots, including savings and smaller funds for predictable spending like haircuts.
