FAQs
1) Why does the calculator convert everything to monthly?
Monthly normalization lets you compare weekly, yearly, and daily amounts on the same scale. It simplifies budgeting and highlights which recurring costs have the biggest monthly impact.
2) How accurate is the weekly conversion?
Weekly amounts use 52 weeks per year divided by 12 months. It is a standard budgeting approximation and works well for planning, even if specific months vary slightly.
3) What if my income is irregular?
Add separate lines for typical months and use a conservative estimate. You can also increase the projection months to see longer-term averages and build a buffer in your starting balance.
4) Can I track multiple accounts or cash and bank balances?
Yes. Combine them into one starting balance for a quick overview, or run separate calculations per account and export each report for comparison.
5) What does a negative net balance mean?
A negative net balance means expenses exceed income on a monthly basis. Review the top expense categories and reduce discretionary costs or increase income sources to move positive.
6) How should I use the savings rate?
Savings rate shows how much of your income remains after expenses. Many budgets target 10–20% or more, but the best rate depends on debt, goals, and living costs.
7) Does the savings goal include investments?
The goal compares against the projected closing balance. If you want to include investments, add them to the starting balance or list contributions as an expense to reflect cash outflow.
8) Why is my goal status “No goal set”?
If the goal field is zero or empty, the calculator assumes you are only tracking cash flow and balances. Enter any positive number to enable the goal comparison.
