Real numbers,
real timelines.
Anonymized case studies showing what the financial decisions on this site actually look like over time. Real starting points, real monthly amounts, modeled outcomes.
These are scenarios based on common starting points. Some composite, all plausible based on historical data. The names are made up. The scenarios are modeled; the math is real. Cases 1-3 project index returns at 7% real; Case 4 runs actual monthly Bitcoin closing prices. The goal is to show what the decisions in the order of operationsorder of operationsThe recommended sequence for using each spare dollar: build a small emergency fund, capture any free retirement-account match your job offers, kill high-interest debt, fill out a real emergency fund, max tax-advantaged accounts, then invest the rest.Full definition actually produce over 5 to 10 years.
Case 1: Starting at zero at 22
22-year-old. $38,000 first job. $1,200/month take-home after taxes. $800/month rent. $0 in savings. $12,000 in student loans at 5.5%. No 401(k) contributions yet.
What they did in the first 12 months
- Months 1-3: built $1,000 starter emergency fund. Stopped all discretionary spending. Moved checking to Fidelity CMA.
- Months 4-6: aggressive student loan paydown while capturing full employer 401(k) match (3% = roughly $95/month into the plan).
- Months 7-12: student loans paid off. Opened Roth IRAIndividual Retirement Account (IRA)A personal retirement savings account with tax advantages. Two main types: Traditional (tax now, pay later) and Roth (pay now, tax-free forever).Full definition at Fidelity. Started $100/month Bitcoin DCADollar-Cost Averaging (DCA)Investing a fixed amount on a regular schedule regardless of price, to reduce timing risk.Full definition on River.
10-year outcome (2014-2024 historical returns)
Key insight: four decisions. The $1,000 emergency fund. The employer matchemployer matchFree money your employer adds to your 401k when you contribute. Not capturing the full match leaves guaranteed returns behind.Full definition. The Roth IRA. The $100/month into Bitcoin. Ten years later, roughly $210,000. See the DCA math at Bitcoin DCA Backtest.
Case 2: Digging out at 35
35-year-old couple. $110,000 combined income. $28,000 credit card debt across 4 cards, average 22% APRAnnual Percentage Rate (APR)The yearly cost of borrowing money, shown as a percentage.Full definition. $340,000 mortgage remaining. $0 in investments. Two kids.
What they did
- Avalanche method on credit cards. Highest APR first.
- Cut expenses to create $1,800/month margin for debt payment.
- 23 months to pay off all $28,000 in card debt.
- Immediately after: opened Roth IRAs for both spouses.
- Started $200/month combined Bitcoin DCA.
- Resumed 401(k) match capture (had been suspended during debt paydown).
5-year outcome
Credit card interest saved vs minimum payments: approximately $14,000 (avalanche vs minimums over 5 years).
Roth IRAs combined after 5 years: approximately $35,000 (at 7% real, averaging contributions).
Net worth swing: from negative $28,000 (credit card debt) to approximately $65,000 in invested assets, plus mortgage paydown. The decision to fix the debt before investing made this path faster than running both simultaneously.
Case 3: High income, nothing to show for it
40-year-old. $180,000 income. Lifestyle inflationinflationA general increase in prices over time, meaning each dollar buys less than it did before.Full definition consumed everything. $4,200/month mortgage. Two car loans totaling $800/month. $0 in retirement accounts. Some equity in the home.
What they did
- Sold one car. Used proceeds to pay off both car loans ($800/month freed).
- Maxed 401(k) immediately. After-tax impact on take-home: approximately -$720/month (thanks to the 32% federal bracket + state tax savings). See Paycheck Optimizer.
- Opened HSAHealth Savings Account (HSA)A tax-advantaged account for healthcare costs, available with a high-deductible plan; contributions, growth, and qualified withdrawals are all tax-free.Full definition with high-deductible health plan. Maxed to $4,400.
- Started Roth conversionRoth conversionMoving money from a tax-deferred retirement account (where you'll owe tax later) into a Roth account (where everything grows and comes out tax-free). You pay regular income tax this year on the amount moved.Full definition ladder planning for eventual early retirement.
10-year projection vs "stayed the course"
Stayed the course: net worth grows primarily via mortgage paydown and home appreciation. Retirement accounts: $0. Projected retirement age to reach $1M: approximately 65.
Changed course at 40: at 50, approximately $385,000 in tax-advantaged retirement accounts (401(k) + HSA + Roth conversion ladder). Retirement achievable at 58 instead of 65.
Case 4: The $100/month Bitcoin decision (January 2017)

What actually happened
Using actual monthly closing prices from the same dataset that powers the Bitcoin DCA Backtest tool, over ~111 months (January 2017 to April 2026):
What they lived through
- Bought through the peak of the 2017 bull run at $13,880/BTC in December 2017.
- Bought through the 2018 crash all the way down to $3,742/BTC in December 2018.
- Bought through 2019 while Bitcoin was declared dead multiple times.
- Bought through the 2022 crash to $16,547/BTC after FTX collapse.
- Kept buying. Never timed anything. Never sold.
This person never timed the market. They bought through the 84% crash. They bought when Bitcoin was "dead" in 2018 and 2019. The discipline of the DCA, not skill, not timing, produced the result.
Run any start date and amount yourself: Bitcoin DCA Backtest. Historical returns are not a forecast. The point of this case study is not the return figure. The point is the behavior: consistent monthly buys through multiple 70%+ drawdowns without selling.
