To increase your household income, consider picking up a second or third job. Start a side hustle such as building websites, walking dogs, babysitting, or driving for a rideshare company. The more money you bring in, the easier it is to meet your savings goals.
You can also consider going to your employer and asking for a raise. Just make sure it's a good time to do so—meaning the company is profiting and you're bringing value to your team.
