Stock Return Demystified: Capital Gains, Dividends, Taxes, and Fees — All in One Guide

Stock Returns Are More Than “How Much Did It Go Up?”

A 30% price increase sounds great — but your actual take-home return depends on commissions, taxes, and dividends. The real formula:

Total Return = (Sale Price + Dividends Received − Purchase Price − Commissions − Taxes) / Purchase Price × 100

1. Key Numbers at a Glance

3. Taxable Account vs. Tax-Advantaged Account

Taxable Brokerage vs. Retirement Accounts
구분
Capital gains taxed at 0/15/20% (long-term) or ordinary rate (short-term) Traditional IRA/401(k): gains tax-deferred; Roth: gains tax-free
Dividends taxed in year received (qualified or ordinary rate) Dividends reinvest tax-free until withdrawal (Traditional) or permanently (Roth)
Tax-loss harvesting available to offset gains No tax-loss harvesting benefit inside these accounts
No contribution limits; fully flexible withdrawals Contribution limits apply ($7,000/yr IRA; $23,500/yr 401(k) in 2025)

At year-end, you can sell losing positions to realize losses that offset capital gains elsewhere in your portfolio. Key rules:

  • The wash-sale rule disallows the loss if you repurchase the same or substantially identical security within 30 days
  • Losses first offset gains of the same type (short/long-term), then can offset up to $3,000 of ordinary income per year
  • Unused losses carry forward indefinitely

4. US Brokerage Commission Comparison

BrokerStock/ETF TradeOptions per ContractNotable Feature
Fidelity$0$0.65No account minimums; fractional shares
Charles Schwab$0$0.65Strong research tools; no minimums
Robinhood$0$0Commission-free options; beginner-friendly
TD Ameritrade / Schwab$0$0.65thinkorswim platform for active traders
Interactive Brokers$0 (IBKR Lite)$0.65Best for international and margin trading

Commission-free brokers generate revenue through payment for order flow (PFOF), which may mean slightly worse execution prices. For most buy-and-hold investors the impact is negligible, but active traders may get better fills at non-PFOF brokers.
