You want me to save $620 a month? How?
Last week, I talked about needing to save $620 per month for the next 40 years to reach $2 million.
The question I received was simple, but common:
Where do I get the $620 from?
This is possible, and I will help you find it so you can be on your way towards the $2 million.
To make this concrete, I’ll use an example based on some of my recent graduates’ compensation packages. On average, they earn $65,000 and receive a 50% 401(k) match up to 6%.
Recall: this savings target is designed to support $80,000 in annual retirement spending—that’s $15,000 more than their current gross income.
Starting Point
Salary: $65,000
401(k) contribution (6%): $3,900/year (pre-tax)
Health insurance: $1,800/year (pre-tax assumption)
Adjusted Gross Income (AGI): $65,000 − $3,900 − $1,800 = $59,300. Contributions to retirement and health insurance are deducted from gross income before taxes are calculated. You can reduce your taxable income by contributing more to your 401 (k).
Federal Taxable Income
AGI: $59,300
Standard deduction (~$14,600)
Federal taxable income ≈ $44,700.
Now that we have calculated your taxable income, we can estimate the taxes you will pay. Your total taxes will vary by geography, and therefore, these are estimates.
Estimated Taxes (Cincinnati Resident)
1. Federal Income Tax
On ~$44,700 taxable income → ~$5,100–$5,800
2. FICA (not reduced by 401 (k) or health premiums)
7.65% × $65,000 = $4,973
3. Ohio State Tax
On ~$59,300 income → ~$1,700–$2,100
4. Cincinnati Local Tax (1.8%)
1.8% × $65,000 = $1,170
These are estimates. Below, I share more information on how you can calculate your own taxes based on your Zip Code.
Total Taxes
$12,900 to $14,000. Let us use the top figure ($14,000) here to calculate your net pay.
Net Pay Estimate
Gross income: $65,000
401(k): −$3,900
Health insurance: −$1,800
Taxes: − $14,000
Estimated take-home pay: $45,300/year
Monthly Take-Home
The take-home pay will be approximately ~$3,775 per month. Now you can budget for your other needs and wants. But did you get to the $620 in savings?
Now, Put This in Context
401(k) contribution: $325/month (already automated)
Employer match: ~$162/month (bonus, not from you)
Total invested already: ~$487/month
Target: $620/month
Remaining gap: ~$130/month. You can either increase your 401 (k) contribution or save an additional $130 from your net pay in an after-tax account. There are tradeoffs between tax advantages and liquidity. If you are looking to maximize your 401K contribution, the 2026 tax structure allows you to contribute up to $24,500 annually. In the above example, you are only contributing $3,900 per year. Let us assume you invest it in an after-tax savings account, you will have $3,645 to live on.
Can you live on $3,645?
Based on the above analysis, you will have your retirement figured out and can now use $3,645 to live on and save and invest for other purchases. How would you budget your first $3,645?

It is that time of year, job offers are being sent out to my students. In addition to helping them navigate negotiating their first offer, we begin the planning process for their first paycheck.
How much will your first paycheck be if you accept a job that pays $60,000 a year in Cincinnati, Ohio?



Playing with your model - assumes single person.
$1422 - average rent for 1 bedroom in Cincinnati (Zillow)
$140 - power bill using EIA data from Jan 2025
$15 - Renter Insurance
$229 - Lease for '26 Toyota Corolla (Toyota Financial estimate) I drive a Volvo XC60 ($1k, but I own it)
$171 - Car Insurance
$211 - food costs https://www.bls.gov/regions/midwest/summary/BLSSummary_Cincinnati.pdf
$100 - using $3.79 Regular gas price off RT 71 at a Shell station refilling 2x per month
$100 - eat out?
$200 - clothing (highly variable based on need/preference)
$30 - cell phone on Mint (unlimited plan)
$2618 for what I would call necessities, leaving $1027. I consciously ignored furniture, entertainment, personal care items, outlier medical inputs.
Now the tough choice, establishing an emergency fund versus that $130 investment gap. IF you have the slack? Both... but if you have to make the decision, both just in smaller amounts. Hardship loans against 401k is the last resort since incurring penalties isn't good.
