20s Starter Budget
A realistic monthly budget for a 20-something making $45K–$120K. Opinionated: save first, no car payment, no carried balance. Tune any number; the math runs live.
FL/TX/WA/NV/SD/TN/AK/WY = 0%. NY/CA/HI ~9-10%. Rough effective rate after standard deduction.
Pre-tax. At least enough to capture your employer match (usually 4-6%).
Monthly take-home
$3,840
After federal tax, FICA, state tax, and pre-tax 401(k). This is what hits your bank account.
Monthly budget
💚 Save (the goal: 20%+ of gross)
Roth IRA
Max is $583/mo for 2026 ($7K/yr). Tax-free for life.
Emergency fund top-up
Until you have 3-6 months of expenses parked in HYSA.
Taxable brokerage
After Roth max + 401(k) match captured. Optional.
🏠 Needs (target: under 50% of take-home)
Rent
Old rule: ≤ 30% take-home. In high-cost cities, share an apartment.
Utilities (electric, water, gas)
~$80-150 depending on city + apartment size.
Phone
Prepaid (Mint, Visible) ~$25. Big-3 carrier ~$80+. Save the difference.
Internet
Often included in rent or split with roommates.
Transportation
Gas + insurance + maintenance — NO car payment. Or transit pass.
Groceries
~$300-500/mo cooking at home. Cheaper if you batch + meal-prep.
Health insurance (post-tax portion)
Usually pre-tax via employer ($0 here). If on a plan you pay, put it here.
🎉 Wants (≤ 20-25% take-home)
Eating out / coffee
The category most 20s underestimate by 2x. Track it.
Subscriptions
Streaming + gym + apps. Audit quarterly with the subscription tool.
Going out / entertainment
Concerts, bars, sports, movies, shows.
Clothing / personal
Skincare, haircuts, clothes. Lumpier than monthly but averages out.
Travel / vacation fund
Set aside monthly so trips don't go on a credit card.
Misc / cushion
Gifts, hobby stuff, the things you forgot to budget for.

Your savings rate (% of gross)
19%
Solid. The Launch principle: hit 20%+ in your 20s and you're set up for an early millionaire age.
The Launch rule of thumb
Aim for: 20%+ of gross to savings, 50% of take-home or less to needs, 25% or less to wants. Hit those and the rest takes care of itself — compounding does the work, lifestyle inflation stays in check, no credit card balance accidentally creeps in.
The single most common mistake at $65K
Putting a $30K new car on a 6-year loan. The $499/mo payment looks "affordable" — but it eats your entire savings room. By 30 you've paid ~$36K plus interest for a car worth $14K, and you've banked nothing. Buy a $10K used car cash. Use the difference to max your Roth and start the snowball. See the Car Payment Trap.
