Formula

The smooth yearly rate that compounds the start into the end over n years — the only honest multi-year comparison.

CAGR = (End ÷ Start)^(1/n) − 1

Explanation

This yearly rate is the time-consistent performance — the figure to rank against benchmarks.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Divide the ending value by the starting value for the total multiple.

Multiple = end ÷ start
Start:$5,000
End:$9,000
Result: 1.800×
Step 2

Take the n-th root for n years, then subtract one.

CAGR = multiple^(1/n) − 1
Years:4
Result: 15.83%
Step 3

Sanity-check: compounding the start at the CAGR must reproduce the end.

Check = start × (1+CAGR)^n
Start:$5,000
Result: $9,000
Final Answer
15.83%

Inputs

Starting Value:$5000
Ending Value:$9000
Holding Period:4

Calculation

1. Divide the ending value by the starting value for the total multiple. → 1.800× 2. Take the n-th root for n years, then subtract one. → 15.83% 3. Sanity-check: compounding the start at the CAGR must reproduce the end. → $9,000

Result

Compound Annual Growth Rate: 15.83%

Interpretation

This yearly rate is the time-consistent performance — the figure to rank against benchmarks.

Understanding Your Result

Your Result: Compound Annual Growth Rate: 15.83%

Typical range: The US market compounds near 10% nominal (~7% real); sustained 15%+ marks an exceptional run.

What This Means

This yearly rate is the time-consistent performance — the figure to rank against benchmarks.

Why It Matters

15.83%/yr over 4y ($5,000 → $9,000; 80.00% total).

Professional Interpretation

15.83%/yr over 4y ($5,000 → $9,000; 80.00% total).

How this is calculated

The smooth yearly rate that compounds the start into the end over n years — the only honest multi-year comparison.

What drives the result

Profit is proceeds minus cost, and return is profit divided by cost. Time turns a total return into a CAGR via compounding, while averaging reshapes the cost base that every future return is measured against. Because fees and dividends hit cost and proceeds directly, the headline return always differs from the bare price move.

Recommendations

  • •Compare CAGR to CAGR only — never to single-year returns.
  • •Volatility drag means the average yearly return overstates the CAGR; this figure is the honest one.

Educational Content

Introduction

Stock returns come from two sources: the price moving and cash paid out along the way. Every figure on this page — profit, return, CAGR, breakeven, average cost — is derived from that single relationship, which is why adding commissions or dividends shifts all of them at once.

Concept Explanation

Profit is proceeds minus cost, and return is profit divided by cost. Time turns a total return into a CAGR via compounding, while averaging reshapes the cost base that every future return is measured against. Because fees and dividends hit cost and proceeds directly, the headline return always differs from the bare price move.

Applications

▸Checking a round-trip trade after commissions and dividends
▸Annualising multi-year gains into a comparable yearly rate
▸Setting breakeven and target prices before entering a position
▸Averaging down or up without losing track of the true cost base

Benefits

  • •Separates price moves from all-in returns including fees and income
  • •Turns holding periods of any length into comparable yearly rates
  • •Makes breakeven and profit targets explicit before emotions intervene
  • •Keeps averaged positions honest about what recovery really needs

Limitations

  • •Ignores taxes, which split short-term gains from long-term rates
  • •Uses nominal dollars — inflation quietly takes 2–3% a year
  • •Past price paths do not predict future returns or volatility
  • •Corporate actions (splits, spinoffs) must be adjusted before comparing prices

Best Practices

  • •Always include both commissions when judging a trade
  • •Annualise before comparing with market benchmarks
  • •Write the exit (target and stop) before entering the position
  • •Recompute the average cost the same day any new lot settles

Common Misconceptions

Myth: Price return equals total return
Truth: Dividends and fees routinely add or subtract several points — price alone understates buy-and-hold wealth and overstates net trading gains.
Myth: A 50% loss needs a 50% gain to recover
Truth: From the lower base it needs 100%. Percentage losses always demand larger recovery gains.

Practical Tips

  • •Compare CAGR to CAGR only — never to single-year spikes.
  • •Extend the window past full cycles for cyclical names.

Common Mistakes

Annualising under a year naively
Sub-year annualisation extrapolates noise — state the period instead.

Assumptions

This calculator makes the following assumptions to provide estimates:

Single start and end, no interim flows: Contributions or withdrawals need IRR/XIRR.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Ignores taxes, which split short-term gains from long-term rates
Limitation: Uses nominal dollars — inflation quietly takes 2–3% a year
Limitation: Past price paths do not predict future returns or volatility
Limitation: Corporate actions (splits, spinoffs) must be adjusted before comparing prices

Frequently Asked Questions

Answers to common questions about this calculator.

Why is CAGR below my average yearly return?
Volatility drag: compounding multiplies, so down years hurt more than up years help.
What is a good CAGR?
About 10% nominal (~7% real) matches the long-run US market; 15%+ sustained is exceptional.
Who uses the stock cagr calculator?
It is used by investors annualising multi-year gains, by advisers benchmarking performance, and by anyone comparing investments over different horizons. It sits in the Stock Profit & Returns group of the Stocks, Dividends & Equities section of Atlascalcs.
How accurate is the stock cagr calculator?
Every figure follows directly from the inputs using standard equity mathematics, so it is accurate to the quality of the values you enter. Broker rounding, corporate actions and tax treatment explain small differences against a statement.
Should I compare total return or price return?
Total return — price plus dividends minus fees — is the wealth you actually keep. Price return alone understates buy-and-hold compounding and flatters active trading.
Does rounding change the results?
Every calculation runs on full precision and rounds only for display. Broker statements round to cents and apply their own corporate-action adjustments, so expect tiny differences.
Are taxes included?
No. Taxes depend on holding period, account type and jurisdiction, so every figure here is pre-tax. Short-term gains and non-qualified dividends are typically taxed as ordinary income.
What should I have ready before using these calculators?
Per-share prices, share counts, commissions on both legs, dividends received, and for valuation the earnings, book, sales, debt, cash and share-count figures from the latest filings.
How do splits affect historical prices?
Split-adjust old prices before computing multi-year returns — otherwise a 2-for-1 split looks like a 50% crash. Data providers usually publish adjusted closes for this reason.
