Mobile Home Calculator
Financing a manufactured home works differently than a traditional house mortgage. This mobile home calculator handles all the common loan types: chattel loans (for homes without land), FHA Title I and Title II manufactured home loans, and conventional real-estate mortgages when the home sits on permanent foundation. Enter your purchase price, down payment, loan type, and term to get the monthly payment, total interest, and total cost.
How a Mobile Home Mortgage Calculator Works
The core formula is the same as any amortizing loan:
Monthly Payment = L * r * (1+r)^n / ((1+r)^n - 1)
Where L is loan amount, r is the monthly interest rate (annual rate / 12 / 100), and n is the number of monthly payments. The mobile home mortgage calculator inputs that formula with loan-type-specific rates.
Mobile Home Loan Types and Rates (2025)
| Loan Type | Typical Rate | Max Term | Requires |
|---|---|---|---|
| Chattel loan | 9-12% | 20-25 yr | Home only (no land) |
| FHA Title I | 7-9% | 23 yr | HUD-approved manufactured home |
| FHA Title II | 7-9% | 30 yr | Permanent foundation + land |
| Conventional | 6-8% | 30 yr | Permanent foundation + land |
Chattel loans finance only the mobile home as personal property. Rates run 1.5-3% higher than conventional mortgages because the home can depreciate and is easier to repossess than real estate. Most used mobile home loan calculator with down payment scenarios assume chattel financing unless the home is on an owned lot with permanent foundation.

Mobile Home Chattel Loan Calculator
A mobile home chattel loan calculator needs three inputs: home price, down payment, and term. Rate varies by credit tier:
- Excellent credit (720+): 8.5-9.5%
- Good credit (660-719): 9.5-11%
- Fair credit (600-659): 11-13.5%
- Below 600: 13.5-16% (if approved at all)
A chattel loan on an $80,000 mobile home with 10% down and a 20-year term at 10% interest is about $695/month principal and interest. That matches the "how much is a monthly payment on a mobile home" question homeowners ask most.
FHA Mobile Home Mortgage Calculator
FHA Title I loans finance manufactured homes as personal property or on rented lots, up to $69,678 for the home only (2025 limit). FHA Title II loans require permanent foundation and treat the home as real estate, following standard FHA limits by county.
FHA rates for manufactured homes in 2025 run 7-9% with 3.5% down minimum. An FHA mobile home mortgage calculator assumes:
- 3.5% minimum down
- Upfront MIP (1.75% of loan) and annual MIP (0.55%)
- 23-year max term for Title I, 30-year for Title II
- Borrower credit 580+ for 3.5% down, 500-579 requires 10% down
Used Mobile Home Monthly Payment Calculator
Used mobile homes finance differently than new:
- Under 15 years old: most lenders finance as chattel or with conventional mortgage
- 15-25 years old: chattel only, higher rates (11-14%)
- Over 25 years old: cash or hard-money loans; traditional financing usually denied
Use the calculator with a custom rate of 11-13% for a typical used mobile home monthly payment estimate. A $40,000 used mobile home with $4,000 down, 20-year term at 12% = $397/month.
Mobile Home Financing Rates
Mobile home financing rates are higher than standard mortgages because:
- Depreciation risk: mobile homes often lose value unlike real estate
- Shorter ages to write off: lenders limit term to home's expected useful life
- Chattel status: easier to repossess but also easier to move, damage, or lose
- Borrower credit mix: average credit score lower for manufactured home buyers
Expect 1.5-3% above prevailing 30-year fixed mortgage rates for chattel. With rates at 6-7% for conventional in 2025, chattel lands at 8-10% for top-tier borrowers, 10-14% for mid-tier.
Mobile Home Interest Rate Calculator
To reverse-engineer the interest rate from a quoted monthly payment, solve the annuity equation for r (no closed form; use Newton's method or a lookup). Our mobile home interest rate calculator lets you plug in the rate directly, making "what if rate was 0.5% lower" scenarios easy to compare.
Example: 0.5% rate drop on $80,000 over 20 years saves about $21/month and $5,000 total interest. A full 1% drop saves $42/month and $10,000 interest.
Should You Use a Chattel Loan or Traditional Mortgage?
If the home will be on an owned lot with permanent foundation, traditional (conventional or FHA Title II) is almost always cheaper. Compare lifetime costs:
- Chattel: $80,000 at 10% for 20 yr = $112,824 interest + principal over life
- FHA Title II: $80,000 at 7.5% for 30 yr = $121,385 but with longer repayment
Monthly payment for chattel runs higher despite shorter term. Run both scenarios through a mobile home calculator to find your best total cost.
