Generally, daily and monthly income in P59 coins depends on two factors:

1) number of masternodes in the P59 network: more masternodes increase the reward time, which leads to the overall reward decrease
2) reward for the current block. The chain is now at the block 28131 with total block reward of 1.2 coins. Block rewards change as the chain moves though blocks. The reward able is on https://prometheus59.net/ ("Technical data" section).

In connection to reward in $ or other fiat currency, that also depends on the current exchange rate, which you can track on https://wallet.crypto-bridge.org/market/BRIDGE.P59_BRIDGE.BTC or https://masternodes.online/currencies/P59/
