Invest-Calc

What if you had started investing 10, 20 or 30 years ago? And what could the next 30 years look like? Invest Calc answers both, with real market history and honest ranges instead of a single rosy number. LOOK BACK AT WHAT REALLY HAPPENED Pick the S&P 500, Dow Jones, Nasdaq or any stock or fund, enter a starting amount and a monthly contribution, and see your plan replayed against real month-by-month prices. You see the dips you would have had to sit through, the biggest drop along the way, and the best and worst years. SEE THE RANGE OF POSSIBLE FUTURES Markets don't move in a straight line. Invest Calc runs 1,000 randomized futures based on an investment's past growth and ups and downs, and shows the middle outcome alongside a good run and a rough run, plus the chance of ending behind. OR USE YOUR OWN NUMBERS Try savings accounts, bonds, a balanced mix or a stock index with ballpark presets, or set your own return and volatility. THE DETAILS THAT MATTER • Fees: see what a "small" yearly fee costs over decades • Inflation: switch everything to today's dollars • Raises: grow your monthly contribution each year • Touch the charts to see any point in time, or drag to compare a stretch • Year-by-year tables SHARE A REPORT Send friends a clean image of your results, with the chart and key numbers, straight from the share sheet. PRIVATE BY DESIGN No account, no sign-in, no ads, no tracking. Your numbers and saved scenarios stay on your device. Only the index or ticker symbol you look up is sent, to fetch its price history. Invest Calc is for education only and is not financial advice. Every figure is hypothetical. Past performance does not predict future results, and real investments can lose value. Taxes are not included.
