I need to calculate RE with the following information:
NI=4,276 and dividends=1,724
Unsure of the formula or if I need any additional info.
Thanks.

You calculate RE like this: Beginning Balance + NI - Dividends

You probably need the beginning retained earnings. Check the balance sheet.

If it is a new company, the RE would be 0.

So it would just be Net Income – Dividends.

But Billy is right, check to see if there was an opening Retained Earnings account.

Thanks.
