Index funds yield 10% a year without the landlord calls. REITs like Realty Income pay 5% monthly. Dropshipping and courses take upfront work before they sleep.
Growing wealth is about putting capital to work, not grinding through another shift. The eight strategies below range from truly passive – set-it-and-forget-it index funds – to active side businesses that eventually run without you. The distinction matters because the effort-to-return ratio varies more than most listicles admit.
Dividends and index funds.
An S&P 500 index fund has returned roughly 10% annually over the long run, about half from price gains and half from dividends. No tenant calls, no product sourcing, no course production. The trade-off: you cannot accelerate the return by working harder. The capital does its job at its own pace. Someone with $50,000 invested sees about $5,000 a year before taxes. That number compounds into something different over two decades.
High-yield savings accounts.
Online banks now offer annual percentage yields above 4% on savings accounts, a sharp contrast to the sub-1% rates at traditional brick-and-mortar institutions. The money is FDIC-insured and liquid. The return will not build wealth on its own – $10,000 at 4.5% earns $450 in a year. What it does is preserve purchasing power on cash that would otherwise sit idle, and it removes the temptation to chase yield into riskier vehicles without a plan.
REITs vs. direct real estate.
Real estate gets the most buzz, but the numbers often work better for real estate investment trusts than for direct ownership. A REIT like Realty Income (ticker: O) yields roughly 5% and pays monthly dividends. No mortgage applications, no tenant screening, no roof repairs. Direct rental property can beat that yield, but only after factoring in leverage, depreciation, and the owner's time. A single-family rental in a mid-tier market might net 8-10% cash-on-cash return after expenses, according to landlord surveys. Stabilization takes months of active work – finding the property, financing, renovations, screening tenants. After that, the checks arrive monthly.
Affiliate marketing and digital products.
Affiliate marketing means placing tracked links to products or services. When a reader clicks and buys, the publisher earns a commission that can range from a few dollars to several hundred. The income runs 24 hours a day once the content is live, but building the audience requires months or years of consistent publishing.
Digital products – eBooks, software, video courses, music files – follow the same arc. Create the asset once, sell it repeatedly through platforms like Teachable, Podia, Kajabi, or Udemy. The upfront production time is significant. A well-produced online course can take 50 to 100 hours to script, record, and edit. After launch, a course can generate revenue for years with minimal maintenance. The creator keeps roughly 70-80% of the sale price on most platforms, depending on the pricing tier.
Dropshipping and Amazon FBA.
Dropshipping eliminates inventory risk. The seller builds an e-commerce store through Shopify, lists products from manufacturers, and when a customer buys, the manufacturer ships directly to the buyer. The seller pays wholesale, collects retail, and pockets the difference. No warehouse. No shipping labels.
Amazon FBA – Fulfillment by Amazon – works similarly. The seller sends products to Amazon's warehouses, and Amazon handles storage, packing, and delivery. The seller focuses on sourcing and listing. Both models require upfront product research, supplier vetting, and listing optimization. The passive income arrives after the systems are running. Neither is truly passive during the setup phase.
The through line.
Every strategy on this list follows the same pattern: capital or content goes in first, income comes out later. Index funds and REITs require the least active work after deployment. Rental properties and e-commerce require the most upfront effort. The choice depends on how much time a person has before they need the income to start flowing.
