What is the Money Guys Calculator?
The money guys calculator is a financial planning tool designed to help you project your future net worth based on the core principles advocated by “The Money Guys,” Brian Preston and Bo Hanson. It helps you visualize the power of consistent investing and compound growth over time. This calculator is particularly useful for anyone looking to apply the Financial Order of Operations to their personal finances and understand how their current saving habits will translate into long-term wealth.
Unlike generic retirement calculators, this tool focuses on key metrics emphasized by The Money Guys, such as your savings rate and the clear distinction between your contributions and the growth of your investments. It serves as a motivational and educational resource to help you make smarter financial decisions for a secure future.
Money Guys Calculator Formula and Explanation
The calculator uses a year-by-year compound interest formula to project the growth of your investments. Compounding is the process where your investment returns begin to earn their own returns, creating exponential growth. The core calculation is performed iteratively for each year until retirement.
The formula for the balance at the end of each year is:
Ending Balance = (Starting Balance + Annual Contribution) * (1 + Annual Rate of Return)
This money guys calculator repeats this process for every year from your current age to your chosen retirement age. It allows you to see how your army of dollar bills grows, with investment growth eventually overtaking your direct contributions. For those interested in the details, our investment goal calculator provides more granular options.

Practical Examples
Example 1: The Young Accumulator
Sarah is 25 years old, earns $60,000 a year, has $10,000 saved, and starts investing $500 per month (20% of her income is a great goal, but she is starting here). She expects an 8% annual return and plans to retire at 65.
- Inputs: Current Age: 25, Retirement Age: 65, Gross Income: $60,000, Current Savings: $10,000, Monthly Contribution: $500, Rate of Return: 8%.
- Results: By age 65, Sarah’s portfolio is projected to grow to approximately $1,630,000. Of this, only $250,000 would be her total contributions, while over $1.3 million would be pure investment growth.
Example 2: The Established Saver
John is 40, earns $120,000, and has already built up a nest egg of $150,000. He decides to “hyper-accumulate” as The Money Guys suggest and invests $2,000 per month. He also expects an 8% return and wants to retire at 65.
- Inputs: Current Age: 40, Retirement Age: 65, Gross Income: $120,000, Current Savings: $150,000, Monthly Contribution: $2,000, Rate of Return: 8%.
- Results: By using this money guys calculator, John can project his wealth to be around $2,680,000 by age 65. His dedication to a high savings rate dramatically accelerates his wealth-building journey. This is a key part of a solid retirement savings plan.
How to Use This Money Guys Calculator
- Enter Your Personal Data: Fill in your current age, desired retirement age, gross annual income, current invested assets, and your planned monthly contribution.
- Set Your Expected Return: Input your estimated annual rate of return. A range of 7-9% is historically common for diversified stock market investments, but you should adjust this based on your own risk tolerance and portfolio.
- Click ‘Calculate’: The tool will instantly compute your projected wealth at retirement.
- Analyze the Results: The calculator will show your final projected net worth, your total contributions, and the total growth. Your savings rate is also calculated, a key metric for financial health.
- Explore the Chart and Table: Use the dynamic chart to visualize how your money grows over time. The table provides a year-by-year breakdown of your financial journey.
Key Factors That Affect Your Results
- Time Horizon: The longer your money is invested, the more time it has for compound growth to work its magic. Starting early is the most powerful factor.
- Savings Rate: The Money Guys champion saving 20-25% of your gross income. A higher savings rate, calculated from your monthly contribution and income, directly accelerates your path to financial independence.
- Rate of Return: A higher rate of return will lead to faster growth. This is influenced by your investment choices (e.g., stocks, bonds). Understanding the Roth IRA rules can help you maximize tax-advantaged growth.
- Starting Amount: A larger initial investment gives you a significant head start on the compounding process.
- Consistency: Making regular, automated monthly contributions is crucial for building momentum and taking advantage of dollar-cost averaging.
- Fees and Taxes: While not an explicit input in this simple calculator, real-world returns are impacted by investment fees and taxes. Minimizing these is a key wealth-building strategy.
Frequently Asked Questions (FAQ)
1. How is the savings rate calculated?
The savings rate is your total annual contributions (Monthly Contribution x 12) divided by your Gross Annual Income, expressed as a percentage. The money guys calculator shows this to help you see if you’re hitting the 20-25% target.
2. Is the rate of return guaranteed?
No. The annual rate of return is an estimate. Actual investment returns fluctuate and are not guaranteed. It’s wise to run the calculation with a few different rates (e.g., a conservative 6% and an optimistic 10%) to see a range of possible outcomes.
3. Does this calculator account for inflation?
This is a nominal calculator, meaning it does not automatically adjust for inflation. The final projected amount represents future dollars, which will have less purchasing power than today’s dollars. To account for this, you can use a lower “real rate of return” (e.g., subtract 2-3% from your expected return).
4. Why do The Money Guys emphasize a 20-25% savings rate?
This savings rate is considered a “hyper-accumulation” phase. It provides a powerful balance of enjoying your life today while aggressively saving for a secure financial future, often enabling the possibility of early retirement.
5. Can I use this calculator if I have irregular income?
Yes. If your income is irregular, you can use your average annual income as the input. The key is to be as consistent as possible with your monthly contributions.
6. Does the calculation include my 401k employer match?
To include an employer match, you should add the matched amount to your monthly contribution. For help with this, see our 401k contribution guide.
7. What is the ‘Financial Order of Operations’?
The Financial Order of Operations (FOO) is a 9-step guide created by The Money Guys to help you prioritize your financial decisions, from building an emergency fund to maxing out retirement accounts. This calculator helps with the later stages of the FOO.
8. Where does the term ‘Wealth Multiplier’ fit in?
The Wealth Multiplier is a concept The Money Guys use to show how much a single dollar invested today can grow by retirement. This calculator demonstrates the cumulative effect of that multiplier across all your invested dollars.
