In accounting is pre paid Insurance a debit or a credit?

When you have prepaid insurance, then you must deduct this cost from the relevant year's expenses. Therefore you debit Insurance Prepaid Account and you credit Insurance Account. This leaves you with a new current asset called Insurance Prepaid. Therefore it is a debit.

Prepaid means you paid for something in advance, so Prepaid Insurance is an asset because you have paid for your insurance in advance, which means you have not used your insurance.

Also assets have a normal debit balance.
