Loan-to-cost (LTC) is a real estate finance ratio that compares the amount of a construction or renovation loan to the total cost of the project, land, construction, soft costs, and financing costs. It is expressed as a percentage: a $7 million loan on a $10 million total project cost is a 70% LTC ratio. LTC is the primary underwriting metric for construction loans, [bridge loans](/blog/bridge-loans), and real estate development financing, it tells lenders what percentage of total project cost they are financing, and therefore how much equity the borrower (developer) has at risk. A higher LTC means the lender is taking on more of the project risk; a lower LTC means the developer has more skin in the game.

## LTC Formula

> **LTC = Loan Amount ÷ Total Project Cost × 100**

*LTC's denominator includes all five cost categories, not just construction hard costs.*

**Total project cost includes**:
- Land acquisition cost (or land basis if already owned)
- Hard costs: construction, materials, labour, contractor fees
- Soft costs: architecture, engineering, permits, legal fees, environmental studies
- Financing costs: loan fees, interest reserve during construction
- Contingency reserve (typically 5%–10% of hard costs)
- Developer fees (sometimes included)

**Example**:
- Land: $2,000,000
- Hard costs: $5,500,000
- Soft costs: $750,000
- Financing costs: $300,000
- Contingency (8%): $440,000
- **Total project cost: $8,990,000**
- Loan: $6,500,000
- **LTC: $6,500,000 / $8,990,000 = 72.3%**

## LTC vs. LTV (Loan-to-Value)

LTC and LTV are frequently confused but measure different things:

*Same $6.5M loan on a $9M project reads as 72.3% LTC but only 54.2% as-completed LTV, the gap is the developer's profit margin.*

| Metric | Formula | Denominator | Used When |
|---|---|---|---|
| LTC (Loan-to-Cost) | Loan / Total Project Cost | What it costs to build | During construction/development |
| LTV (Loan-to-Value) | Loan / Current Appraised Value | What it's worth today | Permanent/stabilised financing |
| ARV LTV (After-Repair Value) | Loan / Estimated Completed Value | What it will be worth when done | Bridge lending, fix-and-flip |

**Key distinction**: LTC measures the lender's exposure relative to cost (what you put in); LTV measures it relative to value (what you can get out). In a healthy project, the completed value (LTV denominator) should be greater than the total cost (LTC denominator), that margin is the developer's profit.

**Example illustrating the difference**:
- Total project cost: $8,990,000
- Estimated completed value (as-completed appraisal): $12,000,000
- Loan amount: $6,500,000
- LTC: 72.3%
- As-completed LTV: 54.2%

The spread between LTC and as-completed LTV is the "equity buffer", in this case, the project has $3,010,000 of value above cost.

## Typical LTC Ranges by Loan Type

| Loan Type | Typical Maximum LTC |
|---|---|
| Construction loan (bank/credit union) | 65%–75% |
| Multifamily construction (Fannie/Freddie) | Up to 80% |
| Fix-and-flip bridge loan ([hard money](/blog/soft-money-vs-hard-money)) | 85%–90% LTC |
| Ground-up development (private equity) | 65%–75% |
| SBA 504 construction | Up to 90% (combined with borrower equity) |
| CMBS construction | 65%–70% |

Lenders typically want 25%–35% developer equity in a construction project. This ensures the developer has a significant financial stake in completing the project and will not walk away if conditions deteriorate.

## How Lenders Use LTC

**Loan sizing**: The lender calculates total project cost from the developer's budget, then applies their maximum LTC to determine the maximum loan amount. The developer must fund the remainder as equity.

**Risk assessment**: A higher LTC ratio means the lender is financing more of the risk. If construction costs overrun, the developer's equity is consumed first, but at high LTC ratios (80%+), cost overruns can quickly erode to the lender's position.

**Draws and cost certification**: In construction lending, lenders fund the loan in draws as construction progresses and costs are incurred. They verify that actual costs match the budget before releasing each draw, this is why accurate LTC analysis at origination is critical.

**Recourse provisions**: Construction loans at higher LTC ratios often require personal recourse from the developer, if the project fails, the lender can pursue the borrower's personal assets.

## LTC for Fix-and-Flip Loans

In the residential fix-and-flip market, hard money lenders often underwrite to both LTC and ARV LTV:

**Example**:
- Purchase price: $200,000
- Renovation budget: $75,000
- Total cost: $275,000
- After-repair value (ARV): $375,000
- Loan at 85% LTC: $233,750
- Loan as % of ARV: $233,750 / $375,000 = **62.3% ARV LTV**

Most hard money lenders cap at 65%–75% of ARV, which serves as the binding constraint in higher-value markets.

## Conclusion

Loan-to-cost is the primary lens through which construction lenders size and underwrite real estate development loans, measuring how much of the project cost the lender is financing vs. how much equity the developer is contributing. Typical construction loans cap at 65%–75% LTC, requiring 25%–35% developer equity to align incentives and absorb cost overruns. Understanding LTC alongside as-completed LTV and ARV LTV provides a complete picture of a development project's leverage and risk profile.
