    if the reserve rate is \(r=0.05\) then banks can lend out \(1-r=0.95\); suppose you give A to a bank that then lends out 95% of that M, and then 95% of that lent amount is even further lent out, etc. giving a total of \(S=M+0.95M+\dots+(0.95)^nM+\dots\): $$S=M(1+0.95+0.95^2+\dots)\\0.95S=M(0.95+0.95^2+\dots)\\S-0.95S=M(1)\\0.05S=M\\S=M/0.05=20M$$in other words, a reserve rate of \(r=0.05\) allows for an initial deposit of \(M\) to give rise to (strictly less than) *twenty* times that in terms of loans from the banking system. in particular, a reserve rate of \(r\) gives a geometric series \(S=M(1+(1-r)+(1-r)^2+\dots)=\frac{M}{1-(1-r)}=\frac{M}r\) so the money multiplier is the ratio of the total amount \(S\) of loan money made possible from an initial deposit \(M\), so \(S/M=\frac1r\)
