There is not really a short answer to that question. In the first 9 months you don’t get full payouts. There is a held back percentage that decreases over time. This is to encourage storage nodes to provide long term reliable service. After 15 months you get 50% of what was held back paid out. The rest you will get paid out after you run a graceful exit.
The dashboard shows you how much you were paid out and what was held back. You can also use the earnings estimator here to see what kind of payouts you could expect.
