Start with a monthly budget covering household bills, food, transport, childcare, debt repayments and savings, then compare it with your take-home income. Set realistic spending limits for non-essentials and try to build an emergency fund gradually, even if you can only save a small amount each month. Check whether you qualify for benefits or support using the official GOV.UK benefits calculator, particularly if your income or family circumstances change. Review the budget regularly and consider guidance from a free, regulated money advice service if debt or rising costs are making things difficult.
