Retiring with $1 million or more in the bank could be more doable than you think, especially if you start saving as soon as you enter the workforce.

In a perfect world, you'll start putting your money to work in your 20s in order to reap the full benefits of compound interest. Even if you don't get started until you hit 30, it's still more than possible to build a million-dollar portfolio by the time you're ready to stop working.

Personal finance site NerdWallet created a chart showing the percentage of each biweekly paycheck you'd need to set aside to have $1 million saved by the time you're 67.

The chart assumes you're starting at age 30 with zero dollars invested. It also assumes a six percent average annual investment return and various annual salaries.

Scroll over the chart to see the exact numbers.

Here's how much a 30-year old would have to set aside if she earns:

$40,000: 18.3 percent of each paycheck

$60,000: 12.2 percent of each paycheck

$80,000: 9.2 percent of each paycheck

$100,000: 7.3 percent of each paycheck

$120,000: 6.1 percent of each paycheck

"We see that the higher earners have to put away a smaller percentage of their paychecks to build a million dollars, but it's important to note that when you consider how much you need to save for retirement, a higher earner typically needs a bigger nest egg," Arielle O'Shea, investing and retirement specialist at NerdWallet, tells CNBC Make It.

"That's because he or she is going to want to maintain that higher standard of living, and Social Security will replace less of his or her income."

O'Shea also notes that "the general rule of thumb is to aim to save between 10 percent and 15 percent of your income for retirement. That means the examples here earning $80,000 or more should actually be working to boost their savings rate."

How much you need for your golden years depends heavily on what you want your lifestyle to look like. Do you plan on traveling a lot or buying a vacation home? Do you want to give money to family members?
