Saving a third of your monthly income can be a realistic goal, but it depends on factors such as where you live and your expenses. If you earn $3,000 per month and have moderate expenses such as rent, food, utilities, phone bills, travel, and occasional entertainment, it's possible to save $1,000.

However, it's important to consider the cost of living in your area and your personal financial obligations. It also requires budgeting and the discipline to save consistently to create a viable savings plan.
