Two things determine your return on seeds: What is left with you after sowing (how sacrificial is your seed?) and the soil on which you sowed.
God cares about the poor, therefore when you sow into their lives , He will delivery you in the day of trouble. (Psalm 41:1)
God cares about His prophets and ministers, so when you sow into their lives, you will get a reward. (Matthew 10:41-42)
God cares about His Church, so when you sow into a ministry, you will be rewarded. (Malachi 3:10-12)
If the place you sow into only looks like a ministry from the outside but is devoid of God's presence, then your seeds will yield zero returns (profits).
You can decide to give anybody money if you wish, but if it is a seed, ensure that you are sowing in a place or person that God is interested in.
“Be sure of the soil before you sow your seeds in it. Don't sow your seeds on concrete and expect a return , it will not yield anything.”
Memorise: And these are they which are sown on good ground; such as hear the word, and receive it, and bring forth fruit, some thirtyfold, some sixty, and some an hundred. (Mark 4:20)
