That depends where are you staying. Like even 500 is enough for a decent room in cities like New Delhi but in places like Andaman islands, or Goa in peak season, even 5000 can't buy you a good stay.
Went to Himachal Pradesh from Delhi. Stayed at the GHNP forest guest house and went for trekking. All under 4500 including travel, fooding and lodging. good for budget travelers. not for luxury travelers. will soon be updating the details of the trip.
You can consider COORG/ GOKARNA in Karnataka even hampi and Ofcourse you will have to cut down price in the place you are going to stay and your means of transport!!
Gwalior is also an economical place which you can visit. if you are coming from Delhi in Taj Express ticket price is approx 250/- INR one way. Economical hotels are available under INR 1000/- per night. You can go to 1. GOPACHAL PARVAT, which houses several Mahavir Jain Stone Statues.
2. Gwalior Fort, houses Maan Singh Palace and several temples, a gurudwara, view point ( gives a good view of Gwalior City Below and located on Gopachal parvat. so no extra travel expense.
3. Tansen Makhbara ( Tansen's tomb).
4.Jayvilas Palace. All these under a budget of under INR 5000/- You can squeeze a trip to morena if you take a local transportation in shared ride and take short walks rather then depending on Ola or auto. it will be a tight squeeze tough. https://www.tripadvisor.in/Attractions-g3179396-Activities-Morena_Morena_District_Madhya_Pradesh.html Best to have some extra cash maybe 2500-3000 extra if you want to include morena too.
