About the Monthly Budget Planner
The value of a budget is not the plan, it is seeing the gap between what you expected to spend and what you did. This planner keeps categories simple enough that you will keep using it after week two, and stores everything in your browser's local storage — no account, no bank connection, no data leaving your device. Because it is local, clearing site data will clear your budget, so export or note your figures if they matter.
Please note: this is an educational estimator. It does not account for processing fees, insurance bundling, prepayment penalties, floating-rate resets or local tax rules, so the figure on a real agreement will differ. Use it to compare options, then confirm with your lender or a licensed financial adviser. Full disclaimer.
Frequently asked questions
Is my budget data private?
Yes. Everything is stored locally in your browser and never uploaded.
Will my data survive if I close the tab?
Yes, it is saved on the device. It will be lost if you clear browser data or use private browsing.
What budgeting split should I aim for?
A common starting point is roughly 50% needs, 30% wants and 20% savings, then adjust to your own situation.
Can I use it as a monthly money manager?
Yes. Log income and expenses by category and the running balance shows what is left. As a lightweight manager it is meant for seeing where a month actually goes, not for reconciling bank transactions.
