When banks make use of non-deposit funding then the loan to deposit ratio doesn't tell you how much a marginal dollar of additional deposits would translate into additional dollars of lending.

<p>Banks do not make loans using deposits from their customers. So there is never a risk of running out of money to lend. Banks create money when loans are made, and the money is destroyed when the loan principal is repaid.</p>

I didn't downvote you, but you were probably downvoted for being wrong. Deposits are a source of funding for bank lending. Any bank's public reporting will discuss them, see this one for example: http://eqbank.investorroom.com/download/EQB+MD%26A+and+FS+-+Q4+2020+vSEDAR.pdf

@JamesWattam That's a common misconception. Have a read of this: https://www.bankofengland.co.uk/-/media/boe/files/quarterly-bulletin/2014/money-creation-in-the-modern-economy.pdf

From page 81 of the [Royal Bank of Canada's 2021 annual report](https://www.rbc.com/investor-relations/_assets-custom/pdf/ar_2021_e.pdf), "... relationship-based deposits, which are the primary source of funding for retail loans and mortgages, were $771 billion or 55% of our total funding..."

<p>Say a bank has 1 billion dollars deposited by individuals with bank accounts. How much of this does the banks lend/invest? Obviously it can't lend all of it or when I go to the bank there would be no money for me to take out. I realize this probably varies between institutions but in general about how much.</p>

<p>Also, what factors would contribute to the percentage they lend relative to the amount the bank has. For example, interest rates, inflation etc.</p>

To see how much a bank lends in comparison to deposits, you can look at what is called the [loan-to-deposit](http://www.investopedia.com/terms/l/loan-to-deposit-ratio.asp) (LTD)ratio of banks in their annual reports. Usually it is between 60% and 90% but as you mentioned this can vary upon institutions .. And geographic areas as well ! For instance, in 2015 in the EU [the average LTD ratio was 108%](https://www.eba.europa.eu/-/eba-finds-further-increase-in-eu-banks-capital-ratios-in-2015) whereas in the US the average is about 79%. You can check [per state the LTD ratio from data gathered by the Fed and the FDIC](https://www.federalreserve.gov/newsevents/press/bcreg/bcreg20150629a1.pdf).
