Aggressive. Achievable for households earning $150,000+ or individuals with very high incomes and controlled fixed costs. For most earners, 5 years ($1,508/month) is the more sustainable plan.
When $100,000 in 3 years makes sense
A 3-year, $100,000 target typically appears for one of two reasons: a 20% down payment on a home in a high-cost city ($400,000–$600,000 price range), or a large investment or business capital target with a firm horizon.
$2,620/month requires that your fixed costs — housing, car, food, insurance, debt payments — leave that amount truly available. For a household earning $180,000/year after tax (about $15,000/month), that is 17% of income: aggressive but achievable if housing and transport costs are controlled.
The 5-year alternative at $1,508/month
Adding 24 months to the timeline drops the monthly requirement from $2,620 to $1,508 — a $1,112 reduction per month. At 4% APY, the 5-year version also earns significantly more in interest on the growing balance.
