At the present time, a Dash masternode earns around 1.54 Dash every ca 130 hours which corresponds to an annual payout of 103 Dash for the 1000 Dash collateral.
Your deposit will earn slightly less than the 10.3% percent annual return for mainly two reasons:
Firstly, CrowdNode charges a fee on the fractional payments corresponding to 15% of the total earnings – and
secondly, because the total amount of Dash in the CrowdNode pool is not always an integer times 1000 Dash there will always be some Dash in the pool which is not part of a masternode and not earning any rewards.
In any case, CrowdNode is fully transparent and you can verify for yourself, that your deposits are getting their fair share of the total CrowdNode masternode payouts.
