What Do I Really Need for Income in Retirement?

When people start thinking about retirement planning, one of the first questions they ask is, “What do I need?” But planning around needs is a flawed approach. If we based our lives solely on needs, we wouldn’t take vacations, we wouldn’t drive the cars we enjoy, we wouldn’t buy lake homes or beach houses, and we wouldn’t splurge on experiences with family. Needs are about survival. Retirement, however, should be about living.

Throughout our working years, we strive to build more than the minimum. We save, invest, and work hard not to get by, but to enjoy life. That mindset shouldn’t disappear the day we retire. If anything, retirement requires even more planning, because we have to factor in inflation, taxes, and unexpected expenses while ensuring our income lasts for decades.

The Key Factors That Shape Retirement Income

When planning for income in retirement, there are several moving parts:

  • Taxes: What you keep after taxes matters more than what you withdraw.
  • Inflation: Costs of living will rise, so income needs to grow.
  • Unexpected expenses: Healthcare, family needs, or large home repairs can come at any time.
  • Lifestyle: What you want your retirement to look like should guide your income target.

But before we dive into those complexities, let’s look at a realistic comparison of income while working versus income in retirement.

Case Study: A Couple Making $250,000 in New Jersey *

While Working

  • Gross salary: $250,000
  • 401(k) contribution (pre-tax): $30,000
  • HSA contribution (pre-tax): $5,000
  • Taxable income after pre-tax savings: $215,000
  • Effective tax rate (including FICA): 22%
  • Net after-tax income: $172,000
  • Brokerage savings (after-tax): $5,000
  • Actual lifestyle spending: $167,000

In Retirement

In retirement, they no longer:

  • Save into a 401(k)
  • Save into an HSA
  • Save into a brokerage account
  • Pay FICA or Medicare taxes

They only need enough gross income to cover $167,000 of lifestyle spending.

  • Effective retirement tax rate (federal + state, no FICA): 16%
  • Gross withdrawals needed: $199,000 per year
  • Which nets out to the same $167,000 they were used to living on
  • On a monthly basis: $16,583 gross → $13,917 net
