Excel Add-ins for Private Equity

Private equity work means inheriting models from bankers and management teams, then betting real capital on whether they hold up. The right excel add-ins for private equity help you interrogate an LBO you did not build and find the plug before it costs the fund. ModelMint is a local, no-telemetry Windows toolkit for auditing, cleaning, and shipping those models.

You Did Not Build It, but You Have to Trust It

A PE associate spends as much time reviewing models as building them. The CIM model from the sell-side, the management projections, the consultant's market sizing: each arrives with its own conventions and its own buried assumptions. Before you run returns, you have to know the model is sound.

The expensive mistakes are not arithmetic. They are an aggressive growth rate hardcoded over a formula, a debt schedule that quietly circular-references, or a sensitivity table that does not actually flex the input it claims to.

Hunting Hardcoded Plugs

Find Hardcodes scans a range and flags every constant sitting inside a formula, which is exactly where sell-side optimism likes to hide. In an LBO, that might be a margin assumption typed straight into the EBITDA build or a manual override in the exit multiple. Seeing them listed lets you challenge each one in the data room.

1. Select the operating model and the returns build.
2. Run Find Hardcodes to list every typed number inside a formula.
3. Cross-check each plug against the assumptions tab and the CIM narrative.
4. Flag anything that cannot be sourced as a question for management.

Tracing the Returns Bridge

When the IRR looks too good, Formula Trace walks the chain from the return back to entry multiple, leverage, and exit assumptions so you can see what is doing the work. Find Dependents shows what a single assumption drives, which is essential when you stress an entry price and need to confirm the whole waterfall responds correctly.

• Decompose an IRR into the assumptions that produce it.
• Confirm a sensitivity table actually flexes the cell it references.
• Find every cell a leverage assumption touches before stressing it.
• Catch a debt schedule that breaks under a downside case.

Cleaning Up External Links and Names

Inherited workbooks are full of references to files you will never have. Hardcode Links surfaces external workbook links so you can sever or replace them. Name Scrubber clears out the orphaned named ranges that accumulate when a model passes through three banks, which makes the file faster and easier to read.

Shipping to the Deal Team and LPs

Internal IC memos and LP updates need clean exhibits. Copy as Image drops a returns table into a memo as a picture that will not reflow. Prepare to Share strips the workings before a model goes to a co-investor, and Send Workbook moves the file. Because ModelMint runs locally with no telemetry, confidential deal models never touch an outside server.
