Frequently asked questions
What should I enter as the monthly expense?
One recurring cost, not your whole budget. Rent, a phone plan, a gym membership, insurance or a car payment all work — run the calculator once per expense to see what each one really costs over a year. If you want a single total across several costs, add them up first and enter the sum.
My bill changes every month. Which figure should I use?
An honest average. Add up the last twelve payments and divide by twelve — that smooths out a cold month of heating or a heavy month of driving. Using your cheapest month makes the annual total look better than your bank account will feel.
How do I handle a bill I pay yearly or quarterly?
Convert it to a monthly equivalent before entering it: divide a yearly amount by 12, or a quarterly amount by 3. A $480 yearly premium is $40 a month, and the calculator will then show the same $480 back on the annual line — which is a useful way to check the arithmetic.
Does the yearly total include price increases?
No. It assumes the amount stays identical for all twelve months and for the whole five years. Many bills rise with inflation or with an annual provider price change, so treat the five-year figure as a floor rather than a forecast, and re-run it whenever the price changes.
