Work out baud rate instantly with clear inputs, formula shown and shareable results.
Baud is symbols per second while bit rate is bits per second; they are equal only when each symbol carries one bit, as in plain UART signalling. Frame overhead then reduces useful throughput: 8 data bits in a 10-bit frame means 115,200 baud delivers 11,520 bytes per second.
Baud and throughput
baud = bit rate / bits per symbol; throughput = bit rate x data bits / frame bits / 8
Only for binary signalling. Modems and modern links pack several bits into each symbol, so bit rate can be many times the baud rate.
One start bit, eight data bits and one stop bit. Adding parity makes 11, cutting efficiency from 80% to about 73%.
