Passive Income Builder

Build Income That Works While You Sleep

Simulate building passive income streams through rental properties, dividend stocks, and bonds. See exactly how long it takes to replace your salary — and which combination of assets gets you there fastest.

Income Streams in CapitalLab

Three paths to passive income. One simulator to test them all.

Each income stream has different risk profiles, capital requirements, and growth trajectories. CapitalLab lets you test every combination to find your optimal mix.

Rental Properties

Buy residential and commercial properties that generate monthly rental income. Manage tenants, handle vacancies, and scale your real estate portfolio over 20 simulated years.

$200–$2,000/mo per property

Dividend Stocks

Invest in dividend-paying stocks and index funds. Reinvest dividends to compound your returns, or use them as income. Practice building a portfolio that pays you quarterly.

2–4% annual yield

Bond Interest

Add stability with Treasury, municipal, and corporate bonds. Earn predictable interest income while reducing portfolio volatility. The anchor of any income strategy.

3.5–8.2% annual yield
The Real Estate Path

Build a rental empire, one property at a time

Real estate is one of the most proven paths to passive income. In CapitalLab, you practice the entire journey — buying your first rental, managing cash flow, using equity to acquire more properties, and scaling to a portfolio that replaces your salary.

  • Buy properties from 6 types: single-family, apartments, condos, multi-family, commercial, and land
  • Finance with conventional mortgages, hard money, or owner financing
  • Manage vacancy rates, maintenance costs, and rent increases
  • Use HELOC equity from one property to fund the next acquisition
  • Track cash flow, cap rate, and cash-on-cash return per property
  • See how rental income grows as mortgages get paid down over time

The Dividend Path

Compound dividends into a growing income stream

Dividend investing is the quiet path to passive income. Reinvest dividends in your early years to compound growth, then switch to taking income as you approach your target. CapitalLab tracks every dividend payment and shows you exactly how your income grows quarter by quarter.

  • Invest in 12 real-world tickers with realistic dividend yields
  • Toggle between reinvesting dividends and taking cash income
  • See how dividend growth compounds over 20 years
  • Compare total return vs. dividend-focused strategies
  • Mix dividend stocks with growth stocks for optimal balance
The Hybrid Strategy

The most successful investors combine all three

Rental income for cash flow. Dividends for growth. Bonds for stability.CapitalLab lets you test every combination to find the mix that maximizes your passive income while managing risk.

40–60%

Real Estate: Cash Flow Engine

Rental properties generate the highest monthly income but require the most capital and management. Use leverage to amplify returns and build equity over time.

30–40%

Stocks: Growth & Dividends

Index funds and dividend stocks provide compound growth and quarterly income. More liquid than real estate and easier to scale with smaller amounts.

10–20%

Bonds: Stability & Income

Fixed income from Treasury and corporate bonds provides predictable returns regardless of market conditions. The foundation that protects your portfolio.
