Unpredictable or unexpected spending may lead you to make unwise decisions, further putting you in an undesirable financial situation. An emergency cash fund can help prevent going into debt or depleting other savings. In addition, it reduces your stress and provides a breathing space until you can regroup.
The important thing about building an emergency fund is to start saving whenever possible. It's okay to start small until you can set aside money consistently. You may have to refocus your financial goals and redo your monthly budget, which will challenge your patience. Stay motivated by reminding yourself the payoff is peace of mind. Plus, there is nothing wrong with rewarding yourself when you've reached your savings target.
