📊Investment Return Calculator
Calculate your investment returns including total return, CAGR, real returns, and compare performance against market benchmarks like the S&P 500.
Frequently Asked Questions
What's the difference between total return and annualized return?
Total return is the overall percentage gain/loss over the entire period. If you invest $10,000 and it grows to $15,000, your total return is 50%. Annualized return (CAGR) converts this to a per-year average that accounts for compounding. That 50% over 5 years equals about 8.45% annualized. Annualized returns are better for comparing investments over different time periods. A 50% return in 2 years (22.5% annualized) is better than 50% in 10 years (4.14% annualized).
What's a good investment return rate?
The S&P 500 has averaged about 10% annually over the long term (since 1926), making this a common benchmark. Returns of 15%+ annually are excellent (Warren Buffett averaged 20%). 7-10% is good for diversified portfolios. 5-7% is average. Below 5% is underperforming (you might do better in bonds or index funds). However, past performance doesn't guarantee future results, and higher returns usually mean higher risk. Also consider risk-adjusted returns - a volatile 12% may be worse than a steady 9%.
How do I calculate my investment return if I made regular contributions?
With regular contributions, use the money-weighted return (MWR) or internal rate of return (IRR), which accounts for the timing and size of cash flows. This differs from time-weighted return (TWR), which measures investment performance independent of cash flows. For example, if you invested $10,000 initially, added $500/month for 5 years, and ended with $50,000, your TWR might be 8% but MWR could be 7.5% because contributions dilute percentage gains. Use this calculator's MWR figure for the most accurate picture.
Should I compare my returns to the S&P 500?
Yes, the S&P 500 is the standard benchmark for US stock market performance. If your portfolio returned 7% while the S&P 500 returned 10%, you underperformed by 3 percentage points. However, context matters: (1) If your portfolio is lower risk (more bonds), expect lower returns. (2) During bull markets, active stock pickers often underperform the index. (3) Consider risk-adjusted returns - if you achieved 9% with half the volatility of the S&P 500's 10%, that's arguably better. Most investors (80%+) can't consistently beat the S&P 500, which is why index fund investing is popular.
What's the difference between nominal and real returns?
Nominal return is the percentage gain without adjusting for inflation. Real return subtracts inflation to show your true purchasing power increase. If your investment returned 8% but inflation was 3%, your real return is about 5%. Over 20 years, this difference is huge: $10,000 at 8% nominal becomes $46,610, but inflation means it only buys what $25,642 would have bought initially. Always consider real returns for long-term planning. Historical US stock market real returns average about 7% (10% nominal - 3% inflation). In high-inflation periods like 2022-2023, many investors had negative real returns despite positive nominal gains.
Why Use This Calculator?
ROI Percentage and Dollar Gain Calculation
Calculate return on investment. Invested $10k, now worth $13,500 = $3,500 gain (35% ROI). Shows both dollar profit and percentage return. Compare investment performance across different amounts and timeframes objectively.
Annualized Return Rate Analysis
Convert total return to annual rate. 35% gain over 3 years = 10.5% annualized return (not 11.7% simple). Annualized return enables fair comparison across different holding periods. Critical for evaluating long-term investment strategies.
Time-Weighted vs Money-Weighted Returns
Time-weighted measures investment performance ignoring contributions. Money-weighted (IRR) includes cash flows. $100k growing to $180k with no additions = 80% return. Same with $20k annual contributions = different IRR calculation method.
Real Return After Inflation Adjustment
Nominal 8% return - 3% inflation = 5% real return (actual buying power gain). $10k at 8% nominal = $21,589 in 10 years, but inflation-adjusted = $16,105 buying power (5% real). Real returns show true wealth growth.
After-Tax Return Calculation
Capital gains taxed 15-20% long-term, 10-37% short-term. $5k gain held >1 year taxed 15% = $4,250 after-tax vs <1 year at 24% = $3,800. After-tax return matters more than pre-tax for actual wealth accumulation.
Compare to Benchmark Performance
Portfolio returned 7% vs S&P 500 10% = underperformed 3% annually. Over 20 years, 3% gap costs $180k on $100k initial (your $387k vs index $673k). Benchmark comparison reveals if beating or trailing market.
Step-by-Step Guide
Enter Initial Investment Amount
Input starting capital or portfolio value. Invested $25,000 initially? Enter $25,000. Use actual amount invested, not current value. This is baseline to calculate gain/loss from. Lump sum investments easiest to calculate.
Example:
Example: Initial $10,000, starting portfolio $50,000, original $5,000
Input Current or Final Value
Enter portfolio value now or at sale. Currently worth $32,000? Enter $32,000. Sold for $28,500? Enter $28,500. Use exact value on specific date for accurate return calculation. Don't estimate - use real numbers.
Example:
Example: Current $18,000, ending $42,000, sold for $55,000
Calculate Dollar Gain or Loss
System calculates: Final Value - Initial Investment. $32k - $25k = $7k profit. Negative number = loss. This is absolute dollar return before considering time or percentages. Raw profit/loss amount.
Example:
Example: $32,000 - $25,000 = $7,000 profit (or -$2,000 loss)
Determine Percentage Return (ROI)
Formula: (Final - Initial) / Initial × 100. $7k gain / $25k initial = 28% ROI. Shows return relative to amount invested. 28% return on $25k beats 30% on $10k ($7k vs $3k profit) in dollars but not percentage.
Example:
Example: $7,000 / $25,000 × 100 = 28% ROI
Set Investment Time Period
Enter years or months held. Held 4.5 years? Enter 4.5 years. Precise timeframe needed for annualized return. From purchase date to sale/current date. Calculator converts to years for annualization formula.
Example:
Example: 5 years, 3.5 years, 18 months = 1.5 years
Calculate Annualized Return Rate
Formula: (Final/Initial)^(1/Years) - 1. 28% over 4.5 years = (1.28)^(1/4.5) - 1 = 5.6% annualized. Compound annual growth rate. Enables comparison across different time periods fairly. Standard investment performance metric.
Example:
Example: 28% total over 4.5 years = 5.6% annualized CAGR
Adjust for Inflation (Real Return)
Subtract average inflation from nominal return. 8% nominal - 3% inflation = 5% real return. Inflation averaged 2-3% historically. Real return shows actual purchasing power growth. More meaningful than nominal for long-term wealth.
Example:
Example: 8% return - 2.5% inflation = 5.5% real return
Factor in Taxes on Gains
Long-term gains (>1 year) taxed 0-20%, short-term (<1 year) at ordinary 10-37% rates. $10k gain held 2 years taxed 15% = $8,500 after-tax. Same gain 6 months at 24% = $7,600. Holding period crucial for after-tax return.
Example:
Example: $10,000 gain × 0.15 tax = $8,500 after-tax (long-term)
Include All Fees and Expenses
Deduct management fees, transaction costs, fund expenses. 1% annual fee on $100k over 10 years costs $15k+ in compounding. Net return = gross return - fees. 10% gross - 1.5% fees = 8.5% net to investor.
Example:
Example: 10% gross return - 1% advisory fee = 9% net return
Compare to Relevant Benchmark
Match benchmark to asset class. Stocks? Compare to S&P 500 (10% historic). Bonds? Compare to Aggregate Bond Index (4-5%). Your 7% vs benchmark 10% = 3% annual underperformance. Reveals if strategy working.
Example:
Example: Portfolio 7% vs S&P 500 10% = trailing by 3% annually
Expert Tips & Strategies
Always Calculate Annualized Return for Fair Comparison
Don't compare 50% return over 5 years to 30% over 2 years. Annualize: 50% / 5 years = 8.4% CAGR vs 30% / 2 years = 14.0% CAGR. Second investment far better despite lower total return. Always annualize for accurate performance comparison.
Focus on After-Tax Returns Not Pre-Tax
Pre-tax 12% sounds great, but 32% tax bracket = 8.2% after-tax. That's barely beating inflation. Roth IRA, HSA, 529 plans offer tax-free growth. Municipal bonds tax-exempt. After-tax return determines real wealth accumulation - optimize for this.
Subtract All Fees From Returns Calculation
1% management fee + 0.5% fund expense = 1.5% drag. On 10% gross return = 8.5% net. Over 30 years, $100k at 10% = $1.74M vs 8.5% = $1.28M. Fees cost $460k lifetime. Always calculate net return after ALL costs.
Adjust for Inflation to See Real Wealth Growth
8% nominal return feels great until subtracting 3% inflation = 5% real return. Buying power grew 5%, not 8%. Over 20 years, $100k at 8% nominal = $466k, but 5% real = $265k buying power. Real return matters for retirement planning.
Hold Over 1 Year for Long-Term Capital Gains Rates
Selling at 11 months? Wait 2 more months for long-term treatment. Short-term gain taxed 24-37%, long-term 15-20%. On $20k gain, waiting saves $1,800-3,400 in taxes. Patience literally pays - hold 366+ days whenever possible.
Use Money-Weighted Return (IRR) for Ongoing Contributions
Standard ROI calculation only works for lump sums. Adding $500 monthly? Use IRR (XIRR in Excel) to account for cash flows. Standard calculation overstates returns when you're adding money regularly. IRR shows true personal return rate.
Compare Returns to Opportunity Cost of Index Funds
Your actively managed portfolio returned 8% but S&P 500 index returned 11% = lost 3% annually. Opportunity cost matters. If can't beat index consistently (most can't), switch to low-cost index fund and save time/fees.
Reinvest Dividends for Compound Growth
Taking $2k annual dividends as cash vs reinvesting? Reinvesting compounds. $100k with 3% dividend reinvested at 8% total return = $466k in 20 years. Taking dividends = only $321k. Reinvesting adds $145k (45% more). DRIP maximizes long-term wealth.
Common Mistakes to Avoid
✓ Better approach: Calculating +30%, -10%, +20% as 13.3% average. Actual compound return (CAGR) = 11.4%. Simple average overstates returns when volatility present. Always use CAGR: (Final/Initial)^(1/Years) - 1 for multi-year periods. Math matters - get it right.
✓ Better approach: Calculating 10% return without considering 24% tax on gains. After-tax return = 7.6%, not 10%. Taxable accounts face yearly tax drag, reducing compounding. Roth IRA/401k avoid this. Always calculate after-tax returns for realistic wealth projections.
✓ Better approach: Reporting 9% return but paying 1.25% advisory fee + 0.75% fund expenses = 2% total drag. True return = 7%, not 9%. Over 25 years, 2% annual fees cost $230k on $100k initial. Include ALL costs: advisory, fund expenses, trading fees, taxes.
✓ Better approach: Saying "I made 40% in 5 years" vs "Friend made 25% in 2 years" and feeling superior. Friend's annualized: 11.8% vs your 7.0%. Friend crushed your returns. Always annualize for fair comparison - total returns mislead when time periods differ.
✓ Better approach: Calculating return from market bottom (2009) to peak (2021) showing 14% CAGR. Starting 2007 or ending 2022 = 7% CAGR. Cherry-picked dates mislead. Use consistent periods (full market cycles) or calculate from actual investment date honestly.
✓ Better approach: Celebrating 6% return when inflation was 5% = 1% real return (barely grew buying power). Focus on real returns (nominal - inflation). 6% sounds good but 1% real means nearly broke even vs inflation. Real return determines actual wealth growth.
✓ Better approach: Portfolio averaged 12% last decade, assuming next decade same and planning accordingly. Market conditions change - valuations, rates, economic cycles. Use conservative 7-8% for planning even if historical higher. Overestimating future returns = under-saving risk.
