What is CAGR and how is it different from total return?
Total return is the overall percentage your money grew across the entire holding period, while CAGR (compound annual growth rate) is the single smoothed yearly rate that would take you from your starting value to your ending value if it grew steadily every year. They answer different questions: total return tells you how much you made in all, and CAGR tells you the equivalent average annual pace. A pot that doubles over ten years has a 100% total return but a CAGR of roughly 7.2%, not 10%, because compounding does part of the work. CAGR is the fairer way to compare investments held for different lengths of time, since it normalizes everything to a per-year figure. This calculator reports both the total return percentage and the CAGR alongside your future value, so enter your numbers to see your real annualized growth rate.
Why does my investment look smaller after adjusting for inflation?
Inflation erodes purchasing power, so a balance that looks large in future dollars buys less than the same number does today. The inflation adjustment shows the real value of your investment, restating the future figure in today's money so a big nominal number does not flatter you. If your investment grows at 8% a year but inflation runs at 3%, your real growth is closer to 5%, and over decades that gap compounds into a meaningfully smaller spending figure. Seeing the real value next to the nominal one keeps expectations honest, especially for long retirement or savings horizons where a 30-year projection can otherwise look deceptively rich. This calculator displays the inflation-adjusted value alongside the nominal result, so enter an expected inflation rate to see what your money will actually be worth.
How much do fees and expense ratios reduce investment returns over time?
Fees quietly compound against you, so even a small annual cost takes a large bite over a long horizon. An expense ratio is charged on your whole balance every year, which means it drags on the very gains that would otherwise be compounding. A 1% annual fee may sound trivial, but over 25 to 30 years it can erase a sizable share of your final pot because every dollar lost to fees is also a dollar that never earns future returns. That is why low-cost index funds often beat pricier actively managed funds on net results even before performance is considered. This calculator lets you apply an annual expense ratio and a tax rate on gains, then shows the after-cost outcome. Enter a fee percentage to see exactly how much a seemingly tiny charge costs you across the full term.
What is the Sharpe ratio and why does it matter for investments?
The Sharpe ratio is a risk-adjusted measure of return: it compares how much your investment earns above a risk-free rate against how volatile, or bumpy, that return is. A higher Sharpe ratio means you are being better compensated for the risk you take, while a low one signals you are accepting a lot of volatility for little extra reward. It exists because raw return alone is misleading, since two investments can post the same average gain while one swings wildly and the other stays steady. Comparing Sharpe ratios helps you choose the option that delivers smoother returns for a similar payoff. This calculator reports a Sharpe ratio using your expected return, its volatility, and a risk-free rate, so you can weigh risk rather than chasing the highest headline number. Pick a market preset or enter your own volatility to see it.
Does reinvesting dividends actually make a difference to long-term returns?
Reinvesting dividends, often called DRIP (dividend reinvestment), means using each payout to buy more shares rather than taking the cash, so those new shares then generate their own dividends and growth. Over long horizons this turns dividends into a major engine of total return, because the reinvested payouts compound on top of price appreciation rather than leaking out as spending money. The difference between taking dividends as income and reinvesting them can be substantial across 20 or 30 years, since a steady 2% to 3% yield reinvested annually adds a compounding layer most simple projections ignore. This calculator lets you set a dividend yield and choose whether dividends are reinvested, then folds the result into your future value and CAGR. Toggle reinvestment on and off to see how much the DRIP effect is worth to your final balance.

About the Investment Returns Calculator
The Investment Returns Calculator projects what a sum of money could grow into over time, given an initial amount, a regular contribution, an expected annual return, and a holding period. Enter your numbers and it produces the future value, your total contributions, the profit (total return) and the return as a percentage, plus a year-by-year breakdown and a growth chart. It is built for anyone weighing a decision with a long horizon: deciding how much to put into an index fund, sanity-checking a 401(k) or ISA projection, or comparing a high-yield savings account against the stock market before committing.
Everything runs locally in your browser. Your figures are never sent to a server, there is no sign-up, and saved scenarios live only in your own browser's local storage. Because the math runs on your device, you can model as many what-if scenarios as you like without any cap.
What the calculator models
Most online calculators stop at simple compound interest. This one accounts for the variables that actually move the result:
- Regular contributions (dollar-cost averaging) — add a monthly, quarterly, or annual amount on top of the starting principal, with optional annual increases.
- Compounding frequency — daily, monthly, quarterly, annually, or continuous, since how often interest compounds changes the final figure.
- Inflation adjustment — see the real (today's-money) value alongside the nominal one, so a big future number does not flatter you.
- Tax and fees — apply a tax rate to gains and an annual expense ratio, because a 1% fee quietly compounds against you over decades.
- Dividends and DRIP — set a dividend yield and choose whether dividends are reinvested.
- Withdrawals — model drawing an income from the pot starting in a chosen year.
It also reports the CAGR (compound annual growth rate, the single smoothed yearly rate that gets you from start to finish) and a Sharpe ratio, a risk-adjusted measure comparing your return against its volatility and a risk-free rate.
Presets and scenario comparison
To save you guessing reasonable inputs, the calculator includes eight investment types and a set of market presets that pre-fill sensible return, fee, dividend, and volatility figures. The index-fund preset, for example, uses roughly 10.5% to reflect the S&P 500's long-run average, while a high-yield savings preset uses about 4.5% with zero volatility. These are starting points, not forecasts — you can override every field.
The compare mode lets you run multiple scenarios side by side and overlays their growth curves on one chart, which is the fastest way to see how an extra 1% of return, a higher monthly contribution, or a lower-fee fund changes the outcome over 20 or 30 years.
Why these projections matter
Compounding rewards time more than amount, and the calculator makes that visible. As a rule of thumb, the Rule of 72 says money doubles roughly every 72 ÷ return% years — about every seven years at 10%. Small differences widen dramatically over long horizons, which is exactly why fees, taxes, and inflation deserve to be in the model rather than ignored.
Keep in mind that projections assume a steady average return. Real markets do not deliver the same percentage every year, so treat any single figure as an illustration of one path, not a guarantee. For decisions with real consequences, use the numbers to frame your thinking and confirm them with a qualified financial professional.
Saving and exporting your results
Once you have a scenario you like, copy the headline results to your clipboard or export the full year-by-year schedule as a CSV to open in a spreadsheet. The tool also keeps a short history of recent calculations in your browser so you can return to earlier scenarios — none of which ever leaves your device.
