Replacing $100,000 in retirement takes about $1,083,938 in today’s money. Saving 10% from age 30 gets you to $1,029,665.
Living on $100,000 a year today means covering about $80,000 a year in retirement — the standard 80% replacement, since commuting, payroll tax and saving itself stop. Funding that from age 65 to 85 takes a nest egg of roughly $1,083,938 in today’s money, or $2,572,408 in the actual future dollars you will hold.
Saving 10% of $100,000 from age 30 at a 7% return builds $1,029,665 in today’s money by 65 — that leaves you $54,274 short of the target. The calculator below is set to this scenario: change your age, what you have saved already, or the percentage you put away to see how quickly the gap closes.
