Budgeting and saving money may seem challenging — but the 50-30-20 rule is an easy way for people to get started, said Cathy Curtis, a certified financial planner based in Oakland, California.
When using the 50-30-20 rule, you should "pay yourself first," said Curtis, founder of Curtis Financial Planning and a member of CNBC's Advisor Council.
In other words, set aside the 20% for savings and debt immediately, and then budget the remainder (for needs and wants) afterward.
"Saving [for the future] is as important as every other expense you have," she said.
If you don't, it might mean not having enough money to fund your lifestyle later in life, perhaps even living in poverty, Curtis said.
