Django query returns multiple rows of sum, I only want to display one row

currently the way I have the code written is that I have a model named Finances. I have an aggregate set up so it sums up all of the rows. I am trying to display the outcome of the rows, but when I do it displays a row for every database entry.

I understand that I am grabbing all with .all() in the viewpayout = Finances.objects.all() in views.py, but I am unsure of how this should be written to only display one row.

How would I display only one row that sums up all of the rows for a column? Any help is greatly appreciated!

Below is my code:

views.py

def finances(request):
    viewpayout = Finances.objects.all()

    updatepayout = UpdatePayout()
    updatewithdraw = UpdateWithdraw()
    updatecash = UpdateCash()

    if request.method == "POST":
        if 'add_payout' in request.POST:
            updatepayout = UpdatePayout(request.POST)
        if updatepayout.is_valid():
            post = updatepayout.save(commit=False)
            post.save()
            return redirect("/finances")
        else:
            updatepayout = None


        if 'bank_withdraw' in request.POST:
            updatewithdraw = UpdateWithdraw(request.POST)
        if updatewithdraw.is_valid():
            post = updatewithdraw.save(commit=False)
            post.save()
            return redirect("/finances")
        else:
            updatewithdraw = None
            

        if 'add_cash' in request.POST:
            updatecash = UpdateCash(request.POST)
        if updatecash.is_valid():
            post = updatecash.save(commit=False)
            post.save()
            return redirect("/finances")
        else:
            updatecash = None
            
    return render(request, 'portal/finances.html', {"updatepayout": updatepayout, "updatewithdraw": updatewithdraw, "updatecash": updatecash, "viewpayout": viewpayout})

model.py

class Finances(models.Model):
    payout = models.DecimalField(null=True, max_digits=5, decimal_places=2, blank=True)
    withdraw = models.DecimalField(null=True, max_digits=5, decimal_places=2, blank=True)
    cash = models.DecimalField(null=True, max_digits=5, decimal_places=2, blank=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateField(auto_now=True)

    def __str__(self):
        return self.payout + "\n" + self.withdraw + "\n" + self.cash

    @property
    def Calculate_bank(self):
        totalpayout = Finances.objects.all().aggregate(Sum('payout'))['payout__sum'] or 0.00 
        totalwithdraw = Finances.objects.all().aggregate(Sum('withdraw'))['withdraw__sum'] or 0.00 
        totalbank = totalpayout - totalwithdraw
        return totalbank

    @property
    def Calculate_cash(self):
        totalwithdraw = Finances.objects.all().aggregate(Sum('withdraw'))['withdraw__sum'] or 0.00
        totalcash = Finances.objects.all().aggregate(Sum('cash'))['cash__sum'] or 0.00 
        totalbank = totalwithdraw - totalcash
        return totalbank

finances.html

<li class="list-group-item active" aria-current="true">Finances</li>
  {% for finances in viewpayout %}
  Cash Available In Bank: {{ finances.Calculate_bank }}
  {% endfor %}
  {% for finances in viewpayout %}
  Cash Available On Hand: {{ finances.Calculate_cash }}
  {% endfor %}
  </ul>

This is what is output
I know that I do have 9 entries in the database, and I know that because I have 9 entries, it displays 9 entries. But if I add another it will show 10 and keep increasing. How can I display only one row?

What I have tried:

Changing the viewfinances query from views.py, but I do not know what the query should be or if that will even work.
