Frequently Asked Questions
How does this calculator handle daily expenses?
Enter the average amount you spend per day on each item, such as coffee or lunch. The tool multiplies that by an average of 30.44 days per month to estimate the monthly cost.
Why 30.44 days per month instead of 30?
A year has 365.25 days, which averages out to 30.44 days per month. Using this figure gives a more accurate monthly estimate than assuming every month is exactly 30 days.
What counts as a monthly expense versus a daily one?
Anything billed once a month, like rent, a phone bill, or a streaming subscription, belongs in the monthly section. Anything you spend on most days, like a coffee or a snack, belongs in the daily section.
How is my savings rate calculated?
Your savings rate is the amount left over after subtracting your total monthly spending from your monthly income, shown as a percentage of your income. A higher percentage means you are saving more of what you earn.
What if my expenses are higher than my income?
The tool will show your monthly shortfall in red instead of savings, along with how far over your income your spending is, so you can see exactly how much you need to cut back.
Is my financial information saved or sent anywhere?
No. All calculations happen instantly in your browser as you type. Nothing you enter is saved, stored, or sent to any server, so your numbers stay private.
