If we assume Naruto got hitched very soon after the Last and they had a kid lets say like a year or 2 later. He'd be like 20-21. Add +12 years(which is what Boruto is currently if all the indicators are correct). Naruto is currently 32-33 years of age.

Which also means that Sasuke would be 32-34 years of age. Pretty simple I think once you work it out.
