Abstract Managing a planner's lifetime's financial actions is a key component of personal financial planning. Poor financial planning affects not just an individual's life, but also the lives of their family. It is an important tool for households, as it can help them to make informed financial decisions and achieve their financial goals. This review paper examines the impact of financial planning on household financial behaviour. The findings of the review suggest that financial planning has a favourable impact on household financial behaviour. Households with a financial plan are more likely to have a budget, save for emergencies, and invest for the future. They are also less likely to be in debt. The positive impact of financial planning on household financial behaviour is likely due to a number of factors. First, financial planning can help households to better understand their financial situation and goals. Second, financial planning can help households to develop a roadmap for achieving their financial goals. Third, financial planning can help households to develop financial discipline.
