baseboard heating install

My house already has 2 baseboard heaters in the 2 upstairs bedrooms. They are connected to a 15 V circuit. I am adding 3 additional baseboards downstairs and was wondering what is the best way to do this. If each one of the baseboards are 400W, Am I calculating this right?

Leave the existing 2 baseboards on the 15 amp circuit. Run a new 15 amp circuit for the 3 new baseboards. (3 x 400 = 1200 amps total). 1200 amp / 120 volt = 10 Amp or 15 amp circuit.

Upgrade the existing circuit to 20 amp. Run all 5 baseboards on one 20 amp circuit. (5 x 400 = 2000)
2000 amp/ 120 volt = 16.6 Amp which is close to a 20 amp ..

am I calculating this right? Which option is preferred? Thanks.

Everything you said is correct. Either will work, although your first approach sounds easier to do. You might also want to look into 240-volt heaters. You get twice the power on the same wires.
