Net Worth Forecast

Project Your Financial Growth Over Time

Knowing your net worth today is useful. Knowing where it will be in 10, 20, or 30 years is powerful. A net worth forecast turns your current financial data into a forward-looking projection — so you can make better decisions now instead of guessing about the future.

How the Forecast Engine Works

NetWorthCast doesn't use a single growth rate for your entire portfolio. Each piece of your financial picture is modeled individually:

The result is a projection that reflects how money actually works — not a flat-line estimate based on one number.

What the Forecast Shows

The forecast chart displays three lines over a 30-year interactive timeline:

Total Net Worth
Line 1
Liquid Assets
Line 2
Illiquid Assets
Line 3

Drag the timeline slider to scrub through each year and see exact values at any point. The chart also plots a FIRE threshold line — the amount you need invested for your returns to cover expenses indefinitely. When your liquid assets cross that line, you've reached financial independence.

This gives you a clear picture of not just your total wealth, but how much of it is actually accessible when you need it.

Forecast Scenarios You Can Model

The real power of a net worth forecast is comparing "what if" scenarios. Adjust any input and see the 30-year impact instantly:

What if I get a raise?

Increase your income and see how higher savings compound over decades. A $10k raise invested at 8% adds over $120k in 10 years.

What if I buy a house?

Model the down payment as a one-time event, add mortgage payments to expenses, and add the property as an illiquid asset with its own growth rate.

What if I reduce expenses?

Cutting $500/month frees $6,000/year for investments. Over 20 years at 8% growth, that's an extra $274k in net worth.

What if I relocate?

Moving to a lower cost-of-living area can dramatically accelerate your timeline. Compare cities and see the forecast shift in real time.

Compound Growth Visualization

Compound growth is the engine behind every net worth forecast. Small differences in return rates or time horizons create enormous gaps in outcome.

$100,000 at 8% annual return = $1,006,266 in 30 years

That's a 10x return from compound interest alone — no additional contributions. Now imagine adding $1,000/month on top of that. The same 30-year projection jumps to over $2.5 million.

This is why forecasting matters more than tracking. Tracking tells you where you've been. Forecasting shows you where small, consistent decisions lead over a lifetime.

10 Years
$216k
20 Years
$466k
30 Years
$1.0M

$100k initial investment, 8% annual return, no additional contributions

Frequently Asked Questions

How does a net worth forecast work?

A net worth forecast projects your financial future by compounding each asset individually at its own expected return rate, applying annual growth rates to income and expenses, and accounting for one-time events like bonuses or large purchases. NetWorthCast runs this projection up to 30 years into the future.

What is the difference between tracking net worth and forecasting it?

Tracking looks backward — it records where your money has been. Forecasting looks forward — it projects where your money is going based on compound growth, savings rates, and planned life events. Both are essential, but forecasting lets you make better decisions today.

How accurate is a 30-year net worth projection?

No projection is perfectly accurate over 30 years, but it gives you a realistic range based on your current trajectory. The real value is in comparing scenarios — seeing how a raise, a home purchase, or reduced expenses changes your long-term outcome. Update your inputs regularly for the most useful projections.

Can I model different financial scenarios?

Yes. NetWorthCast lets you adjust income, expenses, asset return rates, and one-time events to model scenarios like getting a raise, buying a house, relocating to a cheaper city, or cutting expenses. Each change updates the 30-year forecast instantly so you can compare outcomes side by side.
