Prime Lending Rate (PLR) is the interest rate at which banks lend money to their most creditworthy customers.
PLR represents the benchmark rate used by banks to price loans for their best customers (with high creditworthiness). Other borrowers are usually charged higher rates depending on risk.
In India, PLR has largely been replaced by modern benchmark systems like Base Rate, MCLR (Marginal Cost of Funds based Lending Rate), and external benchmarks (like repo rate) introduced by the Reserve Bank of India.
"If a bank’s PLR is 10%, its best customers may get loans at or near this rate, while others may pay higher rates."
