How to Calculate Prime Lending Rate

Prime Lending Rate Calculator

The Prime Lending Rate (PLR) is a benchmark interest rate used by banks to determine the interest rates they offer to their most creditworthy customers. It is typically set by a central bank or a major financial institution and serves as a reference point for a wide range of loan products, including personal loans, business loans, and mortgages.

While the exact formula can vary slightly between institutions and economic conditions, a common approach to understanding how the Prime Lending Rate is influenced involves considering the central bank's policy rate and a spread that reflects the bank's own costs and risk assessment. For simplicity and illustrative purposes, this calculator demonstrates a conceptual model where the Prime Lending Rate is derived from a base rate (often influenced by the central bank's target rate) plus a risk premium.



function calculatePrimeLendingRate() { var baseRateInput = document.getElementById("baseRate"); var riskPremiumInput = document.getElementById("riskPremium"); var resultDiv = document.getElementById("result"); var baseRate = parseFloat(baseRateInput.value); var riskPremium = parseFloat(riskPremiumInput.value); if (isNaN(baseRate) || isNaN(riskPremium)) { resultDiv.innerHTML = "Please enter valid numbers for all fields."; return; } if (baseRate < 0 || riskPremium < 0) { resultDiv.innerHTML = "Base Rate and Risk Premium cannot be negative."; return; } // Prime Lending Rate = Base Rate + Risk Premium var primeLendingRate = baseRate + riskPremium; resultDiv.innerHTML = "The calculated Prime Lending Rate is: " + primeLendingRate.toFixed(2) + "%"; }
