Your Wealth Trajectory
What is the Future Wealth Simulator?
The Future Wealth Simulator is a tool designed to show you exactly what your current financial trajectory leads to. Most people think they're "saving" but never see the cumulative result. This simulator closes that gap by projecting your net worth year-by-year, decade-by-decade, until your target age.
Using a compound growth model with realistic assumptions, it accounts for monthly contributions, expected investment returns, income growth, and inflation. The output is a clear, visual representation of where you are headed if nothing changes — and a powerful motivator for what becomes possible if you do change.
How the Math Works
The core formula is the standard compound interest equation with periodic contributions:
Where P is your starting net worth, r is your monthly expected return (annual ÷ 12), n is the number of months, and PMT is your monthly contribution. We also model income growth by scaling your monthly contributions upward at the rate you specify, and adjust the final figure for inflation so you can see real purchasing power.
How to Use This Simulator
- Enter your current age and the age you want to project to (typically retirement age).
- Add your current net worth — total assets minus total debts.
- Set your monthly savings amount and expected annual return on investments.
- Optionally, add income growth (raises, promotions) and an inflation rate.
- Click "Simulate My Wealth" to see your full projection, decade milestones, and today's-dollar value.
Benefits of Visualizing Your Wealth Future
When you see your projected net worth at age 65 laid out as a chart, the abstract idea of "saving for retirement" becomes concrete. A chart showing $1.2M at 65 hits differently than a vague plan to "save more." It also reveals the brutal cost of waiting: a 25-year-old who starts saving $200/month will end up with roughly twice as much as a 35-year-old saving $400/month, despite contributing the same total dollars.
The simulator helps you answer questions like: Should I increase my 401(k) contribution? Is it worth working one extra year? What does starting a side hustle do to my trajectory? Run multiple scenarios and compare.
This tool provides educational estimates only. It is not financial, investment, tax, or legal advice. Real outcomes depend on market conditions, fees, inflation, taxes, personal behavior, and life circumstances.
Results are based on simplified compound growth assumptions. Actual investment returns are not guaranteed and may be higher or lower. See our Methodology and Disclaimer for full details.
How this is calculated
Inputs used
You provide the starting amount, monthly contribution, expected return rate, and time period. Each input affects the result directly — try changing one to see how the projection moves.
Formula (simplified)
Future value is estimated using the standard compound growth formula with a recurring monthly contribution:
FV = P × (1 + r)^n + PMT × [((1 + r)^n − 1) / r]
Where P = starting amount, PMT = monthly contribution, r = monthly return rate, n = number of months.
Assumptions
- Contributions are made every month and grow at the same rate.
- Returns are constant — real markets go up and down.
- No fees, taxes, or inflation are deducted by default.
- Compounding is monthly, not daily.
Limitations
Real portfolios face sequence-of-returns risk, fees, taxes, and behavioral changes (pausing contributions, withdrawing, etc.). Treat the result as a directional baseline, not a forecast.
Frequently Asked Questions
What return rate should I assume?
For a diversified stock portfolio, 7% nominal (5% real after inflation) is a reasonable long-term assumption. Bond-heavy portfolios should use 3–4%. Be conservative — under-promising beats over-promising.
Does this include taxes?
No, this is a pre-tax projection. If your contributions are in a 401(k) or IRA, the tax treatment actually helps long-term growth. If they're in a taxable account, drag from taxes could reduce returns by 0.5–1% annually.
How accurate is the income growth assumption?
Real income growth varies widely by industry, role, and economic conditions. 2–4% is a safe long-term average for most white-collar careers. Adjust based on your field.
What if I have variable income?
Use a 3–5 year average of your savings rate. The model assumes consistency, but real life has ups and downs. The projection is a baseline — actual results will vary around it.
Can I model a one-time windfall?
The current simulator doesn't have a windfall field, but you can incorporate it by adding it to your current net worth. For periodic windfalls, average them into your monthly contribution.
