The following seems to work for me:

--8<---------------cut here---------------start------------->8---
* balance
| Date  | Debit/Credit | Balance |
|-------+--------------+---------|
| Start |              |    0.00 |
| day 1 |       -10.00 |  -10.00 |
| day 2 |        50.00 |   40.00 |
| day 3 |       -20.00 |   20.00 |
| day 4 |        40.00 |   60.00 |
  #+TBLFM: $3=$2+@-1;%.2f::@2$3=0;%.2f
--8<---------------cut here---------------end--------------->8---

Alternatively, use babel with ledger if you want a full accounting
