Monthly expenses refer to the costs that a person or household incurs on a regular basis over the course of one month. These can include bills such as rent, mortgage payments, utilities (electricity, gas, water), phone service, internet service, insurance premiums, and any other recurring expenses like groceries, transportation costs or subscriptions. The total amount of these expenses can vary from person to person depending on their lifestyle, location, income level, and spending habits. Tracking monthly expenses is an important part of personal finance management as it helps individuals understand where their money is going and make informed decisions about budgeting and saving for the future.
