Frequently asked questions
What is a good savings rate?
Many planners suggest 10–20% as a starting goal, but your target depends on your goals and costs.
Should I use net or gross income?
Use the amount you actually receive if that is how you manage cash flow.
Can I use estimated values?
Yes. Refine categories when you have exact figures.
How often should I update my budget?
Monthly is ideal; at minimum after income or major expense changes.
What if my expenses exceed income?
The calculator will show a negative balance — a signal to review spending or income.
