LBO Debt Schedule Builder

Build LBO debt repayment schedules with amortization, optional prepayments, and interest expense.

LBO Debt Schedule Builder

Build detailed LBO debt repayment schedules with mandatory amortization, optional prepayments, and interest expense calculations.

Input your debt parameters

Annual % of initial balance (default: straight-line)

Formula

Mandatory Amortization = min(Initial Debt Balance × Amortization Rate, Beginning Balance)

Optional Prepayment = min(Cash Available, Beginning Balance - Mandatory Amortization)

Total Payment = Mandatory Amortization + Optional Prepayment

Interest Expense = Interest Rate × Average Balance

Average Balance = (Beginning Balance + Ending Balance) / 2

Ending Balance = Beginning Balance - Total Payment

The debt schedule tracks repayment over time, with interest calculated on average balance to account for principal reductions during the period.

Steps

  • Enter initial debt balance (total debt at acquisition).
  • Enter interest rate (annual percentage rate).
  • Enter amortization rate (optional, percentage of initial balance amortized annually).
  • Enter debt term in years.
  • Optionally enter annual optional prepayment amount.
  • Review debt schedule with mandatory amortization, optional prepayments, and interest expense.

Debt Schedule Overview and Why It Matters

The debt schedule governs required and voluntary payments, shapes cash availability, and drives equity value via deleveraging. A precise schedule prevents covenant breaches and quantifies interest drag.

Common LBO Capital Structures

  • Term Loan A: Amortizing, shorter tenor, lower spread.
  • Term Loan B: Minimal amortization/bullet, longer tenor, higher spread.
  • Revolver: Seasonal liquidity, commitment fees, first-out in cash sweeps.
  • Mezzanine/High-Yield: Subordinated, higher cost, often bullet.

Mandatory Amortization Mechanics

Mandatory Amort = min(Initial Balance × Amort Rate, Beginning Balance)

Set per tranche. In down cycles, test if mandatory paydowns are supportable by cash flow.

Optional Prepayments and Cash Sweeps

Cash sweeps accelerate deleveraging, reducing interest and risk. Prioritize higher-cost tranches first unless prepayment penalties dictate otherwise.

Interest Calculation on Average Balance

Interest = Rate × ((Beg Balance + End Balance) / 2)

Average balance captures intra-period principal reduction; using beginning balance overstates interest.

Allocation Waterfall Across Tranches

  1. Pay revolver (if swept) before term loans.
  2. Meet all mandatory amortization by tranche priority.
  3. Apply optional prepay to highest-cost or shortest-tenor tranche, subject to call protection.
  4. Recompute interest on new balances each period.

Stress Tests and Sensitivities

Run cases on: lower EBITDA, higher rates, delayed prepayments, covenant headroom, and bullet refinancing risk. Small rate moves can meaningfully change cash interest and deleveraging speed.

Execution Playbook

  1. Map tranches, rates, amort rules, and call protection.
  2. Build period schedule with mandatory amort and average-balance interest.
  3. Layer cash sweep logic; prioritize by cost/tenor.
  4. Stress rate, EBITDA, and timing; check covenants.
  5. Iterate to maximize deleveraging without liquidity strain.

Conclusion

Well-modeled debt schedules quantify interest drag, guide prepayment choices, and protect covenant headroom. Use average-balance interest, clear waterfalls, and rigorous stress tests to keep leverage on track.

FAQs

What is a debt schedule in LBO?

A debt schedule tracks the repayment of debt over time, including mandatory amortization (required principal payments), optional prepayments, interest expense, and remaining balance. It is essential for LBO modeling and cash flow analysis.

What is mandatory amortization?

Mandatory amortization is the required principal repayment, often expressed as a percentage of the initial loan amount or a fixed amount per period. It ensures debt is repaid over the loan term.

What is optional prepayment?

Optional prepayment is additional principal repayment beyond mandatory amortization, typically funded from excess cash flow. Prepayments reduce interest expense and accelerate debt paydown.

How is interest expense calculated?

Interest expense = Interest Rate × Average Debt Balance. Average Debt Balance = (Beginning Balance + Ending Balance) / 2. This accounts for principal reductions during the period.

How do I calculate ending balance?

Ending Balance = Beginning Balance - Mandatory Amortization - Optional Prepayment. The ending balance becomes the next period's beginning balance.

What is a typical LBO debt structure?

LBO debt typically includes: Term Loan A (amortizing, 5-7 years), Term Loan B (bullet/minimal amortization, 7-10 years), Revolver (revolving credit facility), and sometimes mezzanine debt or high-yield bonds.

How does debt paydown affect returns?

Debt paydown increases equity value by reducing leverage. As debt is repaid, equity value increases dollar-for-dollar, creating returns for equity investors. This is one of the four key LBO return drivers.

What are financing fees?

Financing fees are upfront costs paid to lenders (arrangement fees, commitment fees). They are capitalized and amortized over the debt term as a non-cash expense affecting net income but not cash flow.

How do I model multiple debt tranches?

Model each tranche separately with its own interest rate, amortization schedule, and optional prepayment rules. Sum interest expenses and principal payments across all tranches. Prioritize prepayments based on tranche terms (typically pay down higher-cost debt first).

What is a bullet payment?

A bullet payment is a large principal repayment at maturity with minimal or no amortization during the loan term. Term Loan B and high-yield bonds often have bullet structures, requiring refinancing or sale proceeds at maturity.
