Frequently Asked Questions

What is base income?

Base income refers to the regular, consistent income an individual or entity receives before any deductions, taxes, or changes in expenses. It can include wages, salaries, and other forms of steady earnings.

How can change in expenses impact financial stability?

A change in expenses, whether an increase or decrease, can significantly impact financial stability. An increase in expenses without a corresponding increase in income can lead to income erosion, reducing the amount of disposable income available for savings or investments. Conversely, a decrease in expenses can enhance financial stability by increasing disposable income.

Why is it important to calculate income erosion?

Calculating income erosion is important because it helps individuals and businesses understand how changes in expenses affect their net income. This understanding can lead to better financial planning and decision-making to ensure financial stability and growth.

Can income erosion be reversed or mitigated?

Yes, income erosion can be mitigated through various strategies such as increasing the base income through additional sources of revenue, reducing unnecessary expenses, or optimizing existing expenses. Financial planning and budgeting are key to managing and reversing income erosion.
