How to calculate total of a table?

Question

Look at this table. https://code.sololearn.com/W1e2gaCMCxpp/#css
Daily expenses are not stable its must change everyday. If the value of price change it should automatically calculate the total. How I can do this with javascript?

function getTotal() {
var prices = document.querySelectorAll("tbody tr td:nth-of-type(4)");
var total = document.querySelector("tfoot tr td:nth-of-type(4)");
var sum = 0;
for(price of prices) sum += parseInt(price.innerText, 10);
total.innerText = sum;
}

getTotal();
