You need to work out the signal losses at each amplifier input and at the final output due to loading of source impedances. Go though the signal path multiplying losses and gains to arrive at the overall voltage gain. Then convert this to dB. Alternatively work out each loss or gain in dB and add then to arrive at the total gain in dB. The latter is the more professional method, applicable to complex systems.
