hi i want to apply loop for on this equation const adultPrice = privateAdultPrice + (adults -1) * privateAdultPrice2 and setting the limit on adults that after every 4 it repeats

updateTotal();

function increaseCount(e, el) {
  var input = el.previousElementSibling;
  var value = parseInt(input.value, 10);
  value = isNaN(value) ? 0 : value;
  value++;
  input.value = value;
  updateTotal();
}

function decreaseCount(e, el) {
  var input = el.nextElementSibling;
  var value = parseInt(input.value, 10);
  if (value > 1) {
    value = isNaN(value) ? 0 : value;
    value--;
    input.value = value;
    updateTotal();
  }
}

function decreaseCount2(e, el) {
  var input = el.nextElementSibling;
  var value = parseInt(input.value, 10);
  if (value > 0) {
    value = isNaN(value) ? 0 : value;
    value--;
    input.value = value;
    updateTotal();
  }
}


function calculateTotal() {
  const privateAdultPrice = 500;
  const privateAdultPrice2 = 125;



  const adults = +document.querySelector('#adults').value;


  const isPrivate = document.getElementById('private').checked;
 

  const adultPrice = privateAdultPrice + (adults -1) * privateAdultPrice2

  for (let i = adultPrice ; adults < 5; ++i)

  return i ;
}

function updateTotal() {
  const total = calculateTotal();
  console.log(total);
  document.querySelector('#amount').value = total;

  
}
updateTotal();
<div class="total-price"><label class="total"> Total USD:</label><input type="number" id="amount"class="total" readonly></label> >
<div class="counter1">

  <div class='down' onclick='decreaseCount(event, this)'>-</div>
  <input id="adults" type='text' value='1' readonly>
  <div class='up' onclick='increaseCount(event, this)'>+</div>
</div>
<div style="display: flex; width: 100%">
  <input type="radio" name="occupancy" id="private"  autocomplete="off" checked="checked" onclick="updateTotal()">
  <label for="private">Private</label>
  
  <input type="radio" name="occupancy" id="shared" value="Shared Evening Safari" autocomplete="off" onclick="updateTotal()">
                    <label for="shared">Shared</label>

is it possible or i am in in illusion which is not possible at-all please help me on this one

for (let i = adultPrice ; adults < 5; ++i)

this is the problem i guess its not repeating

edited ------------------------------------------- formula should be applied depending on checkbox let say a person select shared check box then price should change qty 1 = 125 and 125 x qty if private selected then your formula should be applied

for-loop javascript

Maybe this is more what you are looking for?

const [ttl,adults,shared]=["amount","adults","shared"].map(id=>document.getElementById(id));
function calc(){ttl.value=(shared.checked?0:375)*Math.ceil(adults.value/4)+(adults.value*125);}
shared.onclick=calc;
document.querySelectorAll(".updown").forEach(el=>el.onclick=ev=>{
 adults.value=Math.max(1,+adults.value+(ev.target.textContent=="+"?1:-1));
 calc();
});
calc();
<div class="total-price"><label class="total"> Total USD:</label><input type="number" id="amount" class="total" readonly></label>
<div class="counter1">
<div class="updown">-</div>
<input id="adults" type='text' value='1' readonly>
<div class="updown">+</div>
</div>
<div style="display: flex; width: 100%">
  <input type="checkbox" name="occupancy" id="shared">
  <label for="shared">shared evening safari (reduced price)</label>

As soon as a new group of 1 to 4 people is started, a base sum of $375 is added to the per-person charge of $125.

UPDATE

The shared checkbox now replaces the private one. If it is checked then the extra $375 starting each group for 4 will not e applied. If a smaller amount should still be applicable then that must be used in the formular instead of 0 : (shared.checked?0:375).
