Frequently Asked Questions
Why should I budget annually instead of just monthly?
Monthly budgets often fail when non-monthly expenses arrive—such as car insurance, property tax bills, holiday travel, and annual subscriptions. An annual budget captures these irregular expenses so you can set aside funds each month.
