August 8, 2016 to August 7, 2026 — 10.0 years.
Dividends paid by S&P 500 are reinvested in the month they were paid.
Month-end closing prices, with dividends reinvested where the asset pays them. Excludes trading costs, spreads and taxes.
The worst stretch inside it was a -23.9% fall from a previous peak, bottoming out in 2022 — that is the loss you would have had to sit through to reach the number above. Its best complete calendar year was 2019 at +31.4%; its worst was 2022 at -18.2%. Reinvested dividends did 20.0% of the work: the share price alone returned +254.1%, and dividends carried the total to +317.7%. This is the benchmark every other page in this tool is measured against.
All of it computed from the same month-end closes the chart above draws — a description of what happened, not a forecast.

This calculator shows what actually happened to a real price series — nothing more. Past performance is not a guide to future returns, and picking the winners in hindsight is easy in a way that picking them in advance is not. Prices exclude trading costs, spreads, currency conversion and taxes, all of which reduce real-world returns. Nothing here is investment advice; do your own research or speak to a regulated adviser before investing.
