- Subscription creep: 15-20 active subscriptions totaling $300-$400 vs $100 budgeted
- Shopping: Amazon and online retail can silently consume $400-$600/month
- Travel: Lifestyle inflation to premium hotels and business class when economy is sufficient
How Much Should You Be Saving at $100K?
At $100,000, there is no longer an excuse for a near-zero savings rate. Financial advisors generally recommend saving 15-20% of gross income for retirement. At 15% of $100K gross, that is $15,000/year or $1,250/month. Combined 401(k) + IRA contributions can get you close to this target. Beyond retirement, any additional savings builds wealth and options.
