The assets are all the things that you own. Has a debit balance.
The liabilities are all the things that you owe. Has a credit balance.
The capital is the net worth or your investment – mainly initial investment. Has a credit balance.
All the things which you own (mean assets) are financed either with the capital or with borrowed funds; therefore, assets = liabilities + capital. Or in other words your debit balance should be equal to your credit balance.
