Formula Used
Total Income = All income sources added together
Essential Expenses = Housing + Utilities + Groceries + Transport + Insurance + Healthcare + Childcare + Education + Subscriptions
Discretionary Expenses = Entertainment + Miscellaneous expenses
Total Living Expenses = Essential Expenses + Discretionary Expenses
Total Savings = Retirement Savings + Emergency Savings + Sinking Fund Savings
Total Committed Outflow = Total Living Expenses + Debt Payments + Total Savings
Net Cashflow = Total Income - Total Committed Outflow
Savings Rate = (Total Savings / Total Income) × 100
Debt Ratio = (Debt Payments / Total Income) × 100
Emergency Coverage Months = Current Emergency Fund / Essential Expenses

FAQs
1. What does net cashflow mean?
Net cashflow is what remains after living expenses, debt payments, and planned savings are subtracted from monthly income. A positive result shows surplus. A negative result shows a monthly shortfall.
2. Should savings be treated like an expense?
Yes. Planned savings behave like a committed outflow in a cashflow plan. Treating savings this way helps you see whether your current income truly supports your financial goals.
3. What is a healthy savings rate?
A healthy rate depends on goals, debt, and income stability. Many households aim for at least 10% to 20%, but your ideal rate may be higher or lower.
4. Why separate essential and discretionary spending?
Essential costs are harder to cut quickly. Discretionary costs are usually easier to reduce. Separating them helps households react faster when income changes or targets are missed.
5. How is emergency fund coverage calculated?
The calculator divides your current emergency fund balance by essential monthly expenses. The result estimates how many months of core living costs your reserve could cover.
6. What if my result shows a deficit?
A deficit means monthly commitments exceed income. Review discretionary expenses first, then debt structure, then savings pacing. You may also need to improve income or rework targets.
7. Can I use this for weekly planning?
This version is designed for monthly household planning. You can still use weekly amounts, but all values should follow the same time period for accurate results.
8. What is the target gap?
The target gap compares your actual net cashflow with your desired monthly surplus. A positive gap means you beat the goal. A negative gap means you fell short.
