Spending and budgeting tools

Use the numbers you already know. These tools run locally, explain their assumptions, and do not ask for a bank login.

Four private calculators for spending, subscriptions, budgeting, and savings

Match the calculator to your next decision

Start with the question you need to answer, then use the method notes to check what the result can and cannot show.

Spending Analyzer

Reconcile observed cash movement with categorized spending before deciding where the month can change.

What these tools do not do

They do not connect to financial institutions, recommend a particular account, or treat a generic ratio as a personal prescription. Outputs are educational scenarios based on the figures you enter, and each calculator names the evidence it cannot inspect. Review the financial calculator limits before using a result for a real decision.
