What Is a Forward Price? Can Someone Explain It in Simple Terms?

I'm learning about derivatives and came across the term forward price, but I'm a bit confused about what it actually means.

• What exactly is a forward price?
• How is it calculated?
• How is it different from the current market (spot) price?
• Can you explain it with a simple real-life or investing example?
• Does the forward price guarantee that the asset will trade at that price in the future?

I'm looking for an easy-to-understand explanation, especially in the context of stocks, bonds, commodities, or currencies. Thanks in advance!
