Private Equity Purchase Price Calculator
Seller-facing ability-to-pay model. Estimate what a PE buyer could pay, how much would be cash at close, and how rollover or earn-out change the headline number.
Deal Inputs
Operating Assumptions
Real-world costs that reduce returns.
Services: 2-5%, mfg: 5-15%
Cash tied up funding growth
Banking, legal at exit. Typical: 2-5%.
Deal Structure
Layer structure on top of cash at close.
Contingent seller value. Buyer ceiling assumes it gets paid.
Retained equity that reduces cash at close and rides the exit.
Methodology: Seller-facing buyer-ceiling model. It back-solves the price a PE buyer can pay and still hit a target IRR using leverage, capex, working capital, fees, and a conservative exit multiple. Default exit math uses the current EBITDA size bracket and does not assume automatic multiple expansion.
How to Use This PE Purchase Price Calculator
- Enter business financials. Input the business's current EBITDA and expected annual growth rate. Use a normalized, run-rate EBITDA that reflects sustainable earnings after adjustments.
- Set PE deal parameters. Enter the target IRR, hold period, and optional exit multiple. If you leave exit multiple blank, the model uses a conservative default based on the current EBITDA bracket.
- Configure leverage and structure. Set debt, interest rate, fees, rollover, and any earn-out. The tool separates cash at close from headline value so you can see what is actually payable at signing.
- Review the buyer ceiling. The calculator shows the highest price the PE firm can support while still hitting its return hurdle, plus reality-check warnings when the assumptions become aggressive.
What Is Ability-to-Pay Analysis?
Ability-to-pay analysis reverses the usual valuation process. Instead of starting with comps and arguing about the right multiple, it asks what price a buyer can actually support and still hit its return hurdle.
That matters to a seller because it separates the buyer's real ceiling from the headline number. This version is intentionally seller-facing: it shows cash at close, rollover, earn-out, leverage, and a conservative default exit assumption.
It is not a full banker-grade LBO with taxes and layered debt tranches. It is a simplified buyer-ceiling model designed to make the economics legible enough for a seller to negotiate from an informed position.
How PE Firms Determine Maximum Purchase Price
PE firms build a leveraged buyout model to determine the maximum price they can pay. This calculator uses a simplified version of that logic: it projects EBITDA, applies leverage, subtracts fees, capex, and working capital, and then back-solves for the price where the buyer just reaches its target return.
| Return Driver | Typical Contribution | Impact on Max Price |
|---|---|---|
| EBITDA growth | 30-40% of return | Higher growth = higher max price |
| Multiple expansion | 20-30% of return | Higher exit multiple = higher max price |
| Debt paydown | 20-30% of return | More leverage = higher max price |
| Cash flow distributions | 10-20% of return | Higher margins = higher max price |
The interplay of these factors explains why PE firms can sometimes pay higher multiples than you'd expect. But the model is deliberately conservative on exit: leaving the exit multiple blank uses the current EBITDA bracket rather than assuming automatic multiple expansion.
Understanding Your Results
Max cash at close is what the buyer can actually pay you at signing under these assumptions. If you add rollover or earn-out, the headline deal value may be higher than the cash value.
Purchase multiple is the supported price divided by current EBITDA. This is the cleanest way to compare the model output with real transaction comps.
Sponsor equity check separates the equity needed for the purchase from the entry fees. That makes it easier to see why a buyer's all-in cash commitment can be higher than the pure purchase-equity line item.
Conservative exit multiple defaults to the current EBITDA size bracket unless you override it. That keeps the model from quietly baking in multiple expansion just because the business grows.
Private Equity Purchase Price FAQ
How do PE firms determine the maximum purchase price? +
PE firms work backward from their target IRR using an LBO model. This calculator simplifies that into a seller-facing buyer-ceiling view: projected EBITDA, leverage, fees, and exit value are used to solve for the highest supportable price.
What is ability-to-pay analysis? +
Ability-to-pay analysis calculates what price a buyer can actually support and still meet its return requirements. For a seller, that is useful because it clarifies the buyer's ceiling and shows how much of a headline offer is real cash versus structure.
What EBITDA multiple do PE firms pay? +
PE multiples vary by business size and quality. Small businesses ($1-5M EBITDA) typically trade at 4-7x. Mid-market ($5-25M EBITDA) at 6-10x. Larger businesses ($25M+ EBITDA) can command 8-12x or higher. SaaS and technology businesses receive premium multiples due to recurring revenue and scalability. The actual multiple depends on growth, margins, market position, and competitive dynamics.
How does leverage affect the PE purchase price? +
Leverage directly increases the maximum price a PE firm can pay. With more debt, the firm invests less equity and benefits from debt paydown which accrues to equity holders. A deal that works at 5x with no leverage might support 7x with 3x turns of debt. Lenders typically cap senior debt at 3-4x EBITDA based on cash flow coverage ratios.
What IRR do PE firms target? +
Most PE firms target gross IRRs of 25-30% on individual deals, translating to approximately 20-25% net IRR to their limited partners. Growth equity firms may accept 15-20% for lower-risk deals. Search funds typically target 25-35% to compensate for concentrated single-deal risk. The target IRR is the central input in ability-to-pay analysis.
Why does exit multiple matter more than entry multiple? +
The exit multiple determines terminal value, which is usually the largest component of PE return. That is why this calculator defaults to a conservative exit assumption based on the current EBITDA bracket instead of automatically increasing the multiple as the business grows.
