Storj payments are made once a month. So if you start running a node right now, you will not receive a payment until early next month.
To receive payment next month, (1) your setup should be configured correctly (see the Documentation here), (2) you should have data stored on your disk since before the end of the month you are expecting payout for, (3) your uptime should be above 99.3% which translates to a maximum of about 5 hours 6 minutes and 48.2s of downtime a month (see the article If the space I'm sharing goes offline, what happens to the data I'm storing? and the blog Early feedback from V3 storage node operators: You’ve got questions, we’ve got answers!).
The payment are only calculated on a monthly basis, after the month the payout is for has concluded. For the V3 beta network, we now show the history of your previous months' payouts for your payout address on the SNO dashboard .
Payments are calculated based on your usage metrics, these include:
- Amount of stored data (must be continuously available throughout the month).
- Bandwidth used for paid downloads from your node.
