Just sharing my experience. My brother got married last year in Nepal. It was overwhelming. I have experienced this first hand. If you want to host your reception at hotels like Annapurna or Shankar, the cost per plate is Rs. 2100. We had an estimation of 300 guests which brought the total cost to 630000.They charged us Rs. 50,000 more for basic decorations.I think if you choose party palaces, the cost is lot less. We paid Rs 10,000 to Dj. Wedding Nepal charged us 1,25,000 for the whole wedding photography and videography. Gold/diamond and clothes expenses would come around 12,00,000-15,00,000. Other expenses like baaja, gift to relatives etc may be another 5,00,000. And there are many petty expenses involved which we don't notice, but can sum up to large amounts.
