Compare full loan costs and usable cash

The specialist result above covers its stated question. Use this common worksheet to compare a fixed-rate monthly loan on the same basis as other FinToku tools. Enter every field; use 0 only for a cost that does not apply. Amounts are USD.

Principal already includes the financed fee: do not add it again. Record the combined financed/withheld charge once in the included-fees field. An outside cash fee is separate. A creditor payoff is a use of proceeds, not another fee. Enter a balloon only if it is additional to the regular payments.

No loan summary calculated. Missing costs are not treated as zero.

Check the complete monthly housing budget

A specialist tax, escrow, HOA or insurance result can cover only part of the housing bill. Enter each component once below. Annual taxes and property insurance are divided by 12; mortgage insurance and the remaining fields are monthly. A combined mortgage bill must be split before entering it as principal and interest.

No housing summary calculated. Unknown components stay blank.

Upfront closing cash, deposit timing, temporary assessments after the entered period and later cost changes are separate. This total is a household budget, not a servicer’s statement. Test tax and insurance increases.
