About the IRM dividend calculator
The Iron Mountain (IRM) dividend income calculator reconstructs what an actual cash investment would have paid out in dividends. At the split-adjusted closing price of $27.28 on Mar 23, 2010, an investment of $1,000 bought 36.66 shares — the cost basis every payout below is measured against, through Jun 15, 2026.
Across that span those shares have paid $1,364.97 in dividends — about 1.4× the $1,000 invested. Measured against the entry price, yield on cost moved from 3.18% in its first full year (2011) to 11.8% by 2025, reflecting a dividend that has grown far faster than the price originally paid.
These numbers assume every dividend was taken as cash. Reinvesting instead — the DRIP toggle above — would buy additional shares at each ex-date price, compounding the share count and lifting every subsequent payment.
