An FHA comparison starts with two separate budgets: the cash needed at closing and the payments required after closing. This worksheet makes the financed upfront premium, original-LTV insurance duration and entered ownership costs visible, while keeping approval and refinance decisions outside the estimate.

Separate the purchase budget from the financed loan

The home price, cash down payment and financed loan are different amounts. In this worksheet, the down payment reduces the base loan, and upfront FHA mortgage insurance is financed into that base loan. Financing the premium reduces the cash required for that particular charge at closing, but increases the balance on which principal and interest are calculated. It does not make the premium free. Entered appraisal, title and other fixed fees remain part of the cash estimate, while an origination percentage is applied to the base loan.

Compare these amounts with savings that are actually available for the purchase. The optional savings input produces a remaining-cash illustration, including a negative amount when entered savings do not cover the modeled closing cash. It does not establish a required reserve balance or include every possible prepaid item, escrow deposit, lender charge, moving cost or repair. Review a current Loan Estimate before committing funds. A lower monthly payment alone does not show that a purchase is affordable or that its cash requirements can be met.

Read the original insurance schedule rather than a flat estimate

FHA monthly insurance is not one flat rate applied to every loan. The modeled annual rate depends on the original base loan, original loan-to-value ratio and original term. The premium schedule uses the average balances from the original contractual loan schedule, excludes financed upfront MIP from the premium basis and applies the prescribed currency-rounding steps. Consequently, the scheduled monthly charge can change between loan years even when the note rate and principal-and-interest payment stay constant.

The insurance-duration rule is separate from that annual calculation. The charts show the change at 10% down and the scheduled end of premiums where applicable. Reaching a later equity percentage or assuming home-price growth does not automatically cancel FHA MIP. Extra principal payments can pay off the loan earlier, ending future charges with that payoff, but do not rewrite the original annual premium basis in this model. Select a loan year to inspect both the contractual premium calculation and the amount actually charged after applying the scheduled duration. Property tax, homeowners insurance and HOA remain at the entered amounts rather than being forecast automatically.

Use comparisons as conditional cost scenarios

A down-payment comparison changes the amount paid at closing, the base loan, financed upfront insurance and the scheduled mortgage-insurance cost. The preview holds the entered note rate and original term constant so that these effects can be inspected together. A lender may quote different rates or fees for a different loan, and those changes require a separate comparison. The cash-purchase endpoint has no mortgage or mortgage insurance, but the entered ownership expenses and fixed closing fees still remain. It is an illustration rather than an FHA loan.

The conventional comparison uses an illustrative insurance assumption for the selected credit range and its own scheduled cancellation or midpoint rule. It is not a conventional quote or an approval decision. Compare actual offers over the same holding period and include closing costs, remaining balances and any proposed refinancing charges. Home-price growth is only a scenario assumption; it neither guarantees equity nor establishes refinance eligibility. The worksheet also cannot determine the address-level FHA limit, property qualification, credit acceptability, reserves or the complete underwriting outcome. Save or share the complete assumptions when discussing the estimate with a lender.
