How much is $1000 a month for 5 years?

Excuse me, I'm curious to know. If I were to invest $1000 per month for a period of five years, how much would that amount to in total? Could you perhaps give me a rough estimate, taking into consideration the potential fluctuations in the market and assuming an average rate of return? I'm trying to plan my finances for the long term and this information would be invaluable to me. Thank you for your time.
