A leveraged buyout (LBO) is an acquisition of a company financed primarily with debt — typically 50–70% of the purchase price — with the remainder funded by private equity. The target company's own assets and cash flows serve as collateral for the borrowing. Private equity firms use this structure to amplify equity returns: because the sponsor puts in relatively little equity, any appreciation in the business value accrues disproportionately to that equity slice.
LBOs are the cornerstone transaction type for private equity firms. The buyer acquires a business, uses operational improvements and debt paydown to build value over a 3–7 year hold period, then exits through a sale or IPO — returning capital to limited partners with a target return of 20%+ IRR.
This free tool models the core mechanics of an LBO and lets you stress-test returns across any deal. Start by entering your Entry EBITDA and Entry EV/EBITDA multiple to set the purchase price. Add your leverage assumption (Debt/EBITDA) and interest rate to size the debt. Then set your EBITDA growth CAGR, exit multiple, and hold period to model the exit.
The calculator instantly outputs IRR (internal rate of return) and MoM (money-on-money multiple), along with a year-by-year debt schedule, value bridge waterfall, and two IRR sensitivity tables. Advanced features include bolt-on acquisition modeling, management option pool dilution, revenue and margin disaggregation, and detailed FCF build-up with tax rate, D&A, capex, and working capital assumptions.
IRR (Internal Rate of Return) is the annualized return on the equity investment. Most institutional PE funds target a gross IRR of 20–25%+. IRR is sensitive to hold period — the same dollar return over 3 years produces a much higher IRR than over 7 years. This is why sponsors often try to exit early when performance exceeds plan.
MoM (Money-on-Money), also called MOIC (Multiple on Invested Capital), measures total return as a simple multiple of invested equity. A 2.0x MoM means the sponsor doubled their money. Institutional investors typically target 2.5x–3.5x gross MoM over a 5-year hold. Unlike IRR, MoM is unaffected by hold period — it purely measures magnitude of return, not speed.
Both metrics matter. A 3.0x MoM over 7 years is a mediocre deal (≈17% IRR); the same 3.0x over 3 years is exceptional (≈44% IRR). PE fund economics favor IRR because carried interest accrues faster, but LPs care about both.
Leverage is the primary return amplifier in an LBO. By financing a large portion of the purchase with debt and using the company's cash flows to repay it, the private equity firm concentrates value creation in the equity tranche. If a business is acquired at 10x EBITDA and exits at 12x with modest organic growth, the debt paydown alone can generate a 2x+ equity return even with no multiple expansion.
However, leverage cuts both ways. High debt loads increase interest expense, reduce financial flexibility, and amplify losses if the business underperforms. Typical LBO leverage ranges from 4x–7x Debt/EBITDA depending on the sector, cash flow predictability, and credit market conditions. Lenders generally require interest coverage of 1.5x–2.0x minimum.
The Value Bridge in this calculator decomposes your equity return into four distinct sources of value creation:
EBITDA Growth — Operational improvements, revenue growth, and margin expansion increase the business's earnings, which are then multiplied at exit. This is the highest-quality form of value creation and what top-tier PE firms prioritize. Growth might come from organic sales growth, pricing power, cost reduction programs, or geographic expansion.
Multiple Expansion — Buying at a lower multiple than you sell at. If you acquire at 8x and exit at 10x, you benefit from two turns of expansion on the exit EBITDA. Multiple expansion is less reliable than EBITDA growth — it depends on market conditions, investor sentiment, and timing — but can be a powerful tailwind in bull markets.
Debt Paydown — As the company generates free cash flow and repays debt, the enterprise value stays constant but equity value increases. This is mechanical value creation that happens even in a flat business. A company acquired with $400M of debt that repays $150M over 5 years creates $150M of equity value through debt paydown alone.
Bolt-on Acquisitions — Many PE firms pursue a "buy-and-build" strategy: acquiring smaller companies at lower multiples and adding them to the platform, which then exits at a higher consolidated multiple. This multiple arbitrage — buying at 6x and selling the combined entity at 12x — is one of the highest-conviction return strategies in private equity.
In most LBO structures, the company's excess free cash flow is swept to repay debt as quickly as possible — this is the cash sweep mechanism. Faster debt paydown accelerates equity value creation, reduces refinancing risk, and allows for earlier dividend recapitalizations or exit opportunities. The cash sweep is typically the first priority in a company's cash flow waterfall, above capex reinvestment and acquisitions.
Free cash flow conversion — how much of EBITDA translates to actual cash available for debt service — is one of the most critical inputs in LBO underwriting. After taxes, capex, working capital changes, and interest expense, a typical industrial business might convert 35–50% of EBITDA to levered free cash flow. Asset-light businesses (software, services) can convert 60–80%, which is why they command premium multiples.
While every deal is different, experienced practitioners use a few quick benchmarks when evaluating LBO returns. A deal entering at 10x EBITDA with 5x leverage, 10% EBITDA growth, and exiting at 12x over 5 years should generate roughly 20–25% IRR — solidly in institutional territory. The rule of 72 — divide 72 by your IRR to estimate how long it takes to double money — is a useful sanity check: 20% IRR → 3.6 years to double.
Most institutional LBO funds target gross IRR of 20–25% and gross MoM of 2.5–3.5x before fees. After the 2% management fee and 20% carried interest typical of PE funds, net returns to LPs are roughly 5–7 percentage points lower. The J-curve — where returns appear negative in early fund years as fees accrue before investments mature — is another key concept for anyone evaluating PE as an asset class.
