A monthly payment consists of a payment of principal and accrued interest. The principal to interest ratio may vary. If a borrower is delinquent, penalties and late payment charges may be added to the payment. There are two ways to calculate a loan: annuity and differential. To calculate the approximate amount of the payment before the loan is taken out, all you need to know is the loan amount, the interest rate and the term of the loan. It is important to consider that in fact the loan may include a number of other payments, such as for insurance or informing about the transactions. This will be specified in the loan agreement. And in general to calculate the monthly payment you can always use a loan calculator.

An unsecure loan is a loan agreement that does not include any collateral on the part of the borrower, against which the lender grants the requested money. Large loans and mortgages are rarely granted without collateral, which can be either property (movable or immovable) or the borrower's assets.

PMI (private mortgage insurance) cost for FHA (Federal Housing Administration) loans depends on some factors such as credit history and LTV (loan to value) ratio and amounts to $30 to $70 a month.

A loan origination fee is a one-time payment, usually ranging from 0.5% to 1% of the total loan amount, charged by the lender to compensate the costs for processing the loan application. In general, loan origination fees are not required by all loan originating agencies. In fact, they can be even negotiated before you sign a contract. In most cases, however, the absence of a loan origination fee as a separate payment simply increases the interest rate correspondingly.

An FDA (Federal Department of Agriculture) loan means a government low-interest loan system designed for people who are unable to take advantage of a standard mortgage. The main features of FDA loans are that there is no down payment and that the borrower may only purchase a home in clearly designated rural or suburban areas.

A peer-to-peer lending is a way of lending money to unrelated individuals or 'peers' without involving a traditional financial intermediary such as a bank or other financial organization.
