Why small recurring costs are easy to miss
A $5, $12, or $20 charge rarely feels important by itself. The problem is repetition. A charge that looks tiny at checkout can become hundreds of dollars per year when it repeats automatically.
This calculator converts different frequencies into the same monthly and yearly view so you can compare unlike expenses. It is a simple budgeting visualization, not financial advice.
How the calculator works
- Daily expenses are multiplied by 365 and divided into monthly equivalents.
- Weekly expenses are multiplied by 52 and divided into monthly equivalents.
- Monthly expenses are multiplied by 12 for the yearly view.
- Yearly expenses are divided into monthly equivalents and projected across five years.
The five-year figure is a simple projection. It does not account for inflation, investment returns, taxes, interest, price changes, or cancellations.
