ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar.
The Calvin cycle is similar to the Krebs cycle in that the starting material is regenerated by the end of the cycle.
Carbon enters the Calvin cycle and leaves as sugar.
ATP is the energy source, while NADPH is the reducing agent that adds high energy electrons to form sugar.
The Calvin cycle actually produces a 3 carbon sugar glyceraldehyde 3-phosphate.

The Calvin cycle (or Calvin-Benson cycle or carbon fixation) is a series of biochemical reactions that takes place in the stroma of chloroplasts in photosynthetic organisms. It was discovered by Melvin Calvin and Andrew Benson at the University of California, Berkeley with James Bassham also contributing.
How it relates to photosynthesis?
During photosynthesis, light energy is used to generate chemical free energy, stored in glucose. The light-independent Calvin cycle, also (misleadingly) known as the "dark reaction" or "dark stage", uses the energy from short-lived electronically-excited carriers to convert carbon dioxide and water into organic compounds that can be used by the organism (and by animals which feed on it).

Photosynthesis, generally, is the synthesis of glucose from sunlight, carbon dioxide and water, with oxygen as a waste product.
Photosynthesis uses the energy of light to make the sugar called glucose. A simple general equation for photosynthesis follows.
6 CO2(gas) + 12 H2O(liquid) + photons → C6H12O6(aqueous) + 6 O2(gas) + 6 H2O(liquid)
carbon dioxide + water + light energy → glucose + oxygen + water
Photosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules.
During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of glucose.

Calvin Cycle aka dark cycle is occurs in the stroma, four steps 1carbon fixation 2 reduction 3 release of one molecule of G3P and 4 regeneration of RuBP. Functions as a sugar factory within the chloroplast.
