Land Loan Calculator
Calculate monthly payment and total interest on a land loan from price, down payment, rate, and term.
Compares raw, improved, and construction loans.
A land loan is a mortgage used to purchase undeveloped or raw land — not a home or commercial building. Lenders treat land loans as higher-risk than traditional mortgages because land alone generates no income and is harder to sell in a foreclosure, resulting in stricter terms.
Monthly Payment Formula (same as standard amortization): M = P × [r(1+r)^n] ÷ [(1+r)^n − 1]
Total Interest Paid = (M × n) − P
What each variable means:
- M: monthly payment amount
- P: principal loan amount (land purchase price minus down payment)
- r: monthly interest rate = Annual Rate ÷ 12 (expressed as decimal)
- n: total number of monthly payments = Loan Term in Years × 12
How land loans differ from home mortgages:
- Higher interest rates: typically 1–3% above conventional mortgage rates
- Larger down payment required: usually 20–50% (vs. 3–20% for homes)
- Shorter loan terms: commonly 10–20 years (vs. 30 years for homes)
- Stricter income/credit requirements: lenders offset higher risk with tighter underwriting
Land loan types:
- Raw land loan: unimproved land with no utilities or road access. Hardest to finance, highest rates.
- Unimproved land loan: has some infrastructure (utilities nearby) but no structures.
- Improved land loan: platted lots with utilities, roads, and permits. Easiest to finance, closest to residential rates.
Worked example: You purchase a 5-acre rural lot for $120,000. You put 30% down ($36,000) and finance $84,000 at 8.5% for 15 years.
r = 8.5% ÷ 12 = 0.7083% = 0.007083 n = 15 × 12 = 180 payments
M = 84,000 × [0.007083 × (1.007083)^180] ÷ [(1.007083)^180 − 1] (1.007083)^180 ≈ 3.5054 M = 84,000 × [0.007083 × 3.5054] ÷ [3.5054 − 1] M = 84,000 × 0.02484 ÷ 2.5054 M = 84,000 × 0.009913 = $832.71/month
Total paid = $832.71 × 180 = $149,888 Total interest = $149,888 − $84,000 = $65,888
Tip: If you plan to build within 1–2 years, ask lenders about a construction-to-permanent loan that combines land purchase and construction financing into one closing.
