How to Create a Project Finance Model in Excel

This tutorial will show you how to create a Project Finance Model and forecast Cash Flow in Excel with step-by-step instructions, practical examples to download and the calculation of Equity Investment Returns.

First, I will build a simple cash flow forecast for a generic project. Then, I will use that spreadsheet to create a consolidated cash flow financial model. Lastly, I will show how to use those cash flows to calculate return on investment and then see how changes in assumptions impact your overall equity returns.

Download my Project Finance Model Template in Excel to follow the examples from this tutorial.

Step 1. Start with a Cash Flow Template for One Project

To create a Project Finance Model in Excel, start with an empty spreadsheet and type in month numbers in one of the first rows. I will build a monthly cash flow model spread over ten years, so my model will have 120 columns, with one for each month.

Then, below the month rows, add the main drivers of the model, for example, the number of units added or built. For simplicity, I will assume that each unit represents a connected home (for example, a house connected to a fibre or broadband internet network). You could also easily define the driver as a unit of length (for example, the length of the electricity grid) or any other meaningful metric.

Lastly, to make your project finance model user-friendly, use Excel’s freeze panes functions to see what period you are looking at as you scroll through the spreadsheet.

Step 2. Forecast Direct Cost and Revenues in Project Finance

Connect the drivers with the model’s revenue and cost assumptions to calculate Direct Revenues in a Project Finance Model.

For example, if the model assumes 100 new units connected in month one and the upfront fee is $100, the total upfront revenue would equal $10,000 (i.e. 100 new units x $100).

Similarly, link a unit cost assumption to the drivers to calculate Direct Costs. For example, my Project Finance Model Template takes the number of new units and multiplies it by the cost per acquisition assumption to calculate marketing cost.

Notice that I have listed the primary revenue and cost assumptions monthly. Listing the monthly inputs will allow the spreadsheet’s user to see what assumption a calculation uses in a given period. It will also allow you to adjust the pricing or costs to inflation or retail price increases. I have also clearly divided cash inflow into Upfront and Recurring Revenues.

Step 3. Calculate Project’s Operating Expenditures

To calculate operating costs in a project finance model, split the cost into variable and fixed parts. For example, look at how my Project Finance Model calculates the salary costs. Notice that the project’s cash flow forecast divides the employee numbers into two parts:

  • Direct Headcount: driven by the number of units added in your model; for example, you can assume one additional employee per a fixed number of new units,
  • Fixed Headcount: includes central staffing, such as CEO, finance, and other expenses, which will be less sensitive to changes in the number of units.

Step 4. Calculate Capital Expenditure in Your Financial Model

To calculate Capital Expenditure, multiply the number of newly connected units by the per-unit build cost. Split your cash flow projections into phases. For example, divide the timeline into the following periods:

  • Setup period: the time needed to prepare the company for growth. In this period, your model will incur costs with no generated revenues,
  • Growth period: the period in which you accelerate growth and gradually add customers over time.

My Project Finance Model Template assumes a fixed number of new connections over time, but you could also flex it to fit your growth projections.

Notice that the model forecasts capital expenditure differently depending on the period. In the setup period, it takes a one-off cost, for example, R&D or software development, and spreads it over time. In the growth period, it takes the number of newly connected units and multiples by assuming costs.

Step 5. Add Debt to Your Project Finance Model

Adding debt to your project finance model will lower your equity requirement and often increase your overall returns on investment. My Project Finance Excel Template assumes that the main driver of the potential debt level will be an EBITDA.

To calculate the level of annual debt for your project finance:

  1. Set up your Excel template to look back at the previous twelve months of EBITDA.
  2. Use that figure as your basis and multiply it by your project finance model’s Debt-to-EBITDA assumption; that is the maximum debt level you can raise.
  3. Add additional debt to top up your current debt balance to that maximum level.

For example, if in a Cash Flow Forecast, the previous year’s EBITDA was $1.0m and you use a Debt-to-EBITDA multiplier of 5, you can raise debt to a maximum of $5.0m. Hence, if we assume that the Current Debt Closing Balance is $3.5m, you can top it up by $1.5m. Note that using this method, you can only draw debt if EBITDA is positive.

The debt calculation uses assumptions for the number of future repayments. I used Excel’s PMT formula to calculate the total debt payment and then allocated it between the interest and the principal.

As a result of adding debt financing, you will notice that my Project Finance Model now has two kinds of cash flows: unlevered and levered. The difference between those two cash flows is the amount of bank lending invested.

Step 6. Build a Consolidated Project Finance Cash Flow Statement

When you have modelled a Cash Flow Forecast for one project, consolidate it into a series of projects. Combining project cash flows will allow you to see how to use Investment Returns from one project to fund another.

In my example, I assumed a set number of projects with their starting date separated by a fixed period. My Project Finance Model Template uses a dynamic phasing assumption, so you can always change it and see its effect on your overall returns. For example, you can set the template to five projects, with each project starting six months apart.

Lastly, to make the consolidation and flexibility possible, create a ‘Consolidated Cash Flow’ tab and then use Excel’s INDEX formula to aggregate each project’s revenues and costs in one place.

Step 7. Summarise Model’s Cash Flows and Assumptions

Aggregate the Project Finance’s Cash Flow into an annual view. Summarising the monthly output will allow you to build a clear and easily digestible statement of your cash flows and test the impact of your assumption.

Then, use the output to calculate the level of Equity Investment Required. To create the summaries, use Excel’s SUMIFS formula, allowing you to quickly aggregate the main numbers by year.

Lastly, list the main assumptions and metrics next to the summary for ease of presentation and usability. Having the inputs next to the model’s output allows you to test how a change in one assumption affects the overall picture. Try changing the value of one input and see how it affects the cash flow statement.

Step 8. Calculate Equity Returns in a Project Finance Model

The negative cash flows, in summary, represent the level of external equity needed to fund your project finance model. My Project Finance Model assumes three sources of investment:

  1. Revenues: excess cash flow returns from existing projects, decreasing the equity investment.
  2. Debt: loans or other bank funding, usually secured by the historical cash flows generated from projects.
  3. Equity: external investment, filling the cash requirement between the cash required and the funding from existing cash flows and debt.

Make sure to add Return on Investment Calculation to your Project Finance Model. Use Excel’s IRR and NPV formulas to calculate the cash flow’s Return on Equity.

For example, in my Project Finance Model Template, I calculated the annual cash flow to equity and valued the business at the end of ten years. The exit value or any positive cash flow represents the distribution of proceeds or dividends to the equity investors. To calculate the exit or terminal value, take the EBITDA and apply a multiplier relevant to your industry.

Step 9. Stress Test Project Cash Flows and Equity Returns

Download my Project Finance Model Template and change its assumptions to see how they impact your cash flows and the calculation of Investment Returns. A few financial metrics can help you analyse the results. Specifically, pay attention to the return on investment metrics such as IRR or NPV, the level of Equity Required or the Payback Period.

Stress test the model or build scenarios that will break and become unsustainable. For example, you may find that accelerating your build positively affects revenues, but it also increases the overall equity investment required to fund the model.

Similarly, spreading the projects apart may lower your overall returns, but it may decrease your equity requirement as you will have more access to cash from earlier projects.

Lastly, use Excel’s data table to summarise the sensitivity and outputs of the model. In the examples below, I have tested how to change both units built per month and project phasing affects the model, but you can also try different inputs.
