Track income and expenses
The Simple Budget Calculator is a straightforward personal finance tool designed to give you a clear snapshot of your financial health. Based on the 50/30/20 rule or your own custom needs, it allows you to list your monthly income sources against your expenses. It visualizes the data to show exactly how much "disposable income" you have left after bills. Unlike complex banking apps, this tool requires no login and stores no data—it is a quick, private way to run the numbers and plan your monthly savings.
