Excel modeling tests: conventions and build order

The formatting conventions graders expect, the order to build an LBO or three-statement test in, the formulas that come up every time, and the shortcuts worth learning.

Conventions graders look for

  • Blue font for typed inputs, black for formulas, green for links to other sheets.
  • No numbers typed inside formulas: every assumption lives in its own input cell.
  • One formula per row, written once and filled right.
  • Clear signs: decide whether costs are negative and stick to it.
  • Check rows: sources equal uses, the balance sheet balances, debt never goes below zero.

Anchoring: the most common mistake

When you fill a formula right, references move with it. A dollar sign stops that: $B$2 always points at B2. Use it for any single input, like a growth rate, that every year should use.

例题 · Grow revenue at a fixed rate

经代码验证

Revenue is 100 in C3 and the growth rate is 10% in B2. Write one formula in D3 that can be filled right.

查看解题过程
  1. 1.=C3*(1+$B$2): C3 moves to D3, E3… as you fill; $B$2 stays put.
  2. 2.Filled to F3, it gives 110, 121 and 133.1.
  3. 3.Without the anchors, E3 would point at C2, an empty cell, and growth would silently stop.

答案=C3*(1+$B$2), giving 110, 121 and 133.1.

Build order for a timed LBO test

  1. 1

    Read everything first

    Note what must be answered, then set up the timeline and the input block.

  2. 2

    Operating model

    Revenue to EBITDA to free cash flow, year by year.

  3. 3

    Sources and uses

    Price, fees and refinanced debt; debt by tranche; the equity plug. Check sources equal uses.

  4. 4

    Debt schedule

    Opening balance, repayments, closing balance, interest. Use opening balances unless told otherwise, to avoid a circular reference.

  5. 5

    Cash sweep

    Cash available after mandatory repayments, applied by seniority with MIN so no tranche goes below zero.

  6. 6

    Returns

    Exit value, net debt, equity, MOIC and IRR.

  7. 7

    Checks and answers

    Check rows, then the written questions. Leave five minutes for these.

例题 · The sweep formula

经代码验证

50 of cash is available and the loan balance is 80. How much is repaid, and what's left?

查看解题过程
  1. 1.Repayment = MIN(cash available, balance) = MIN(50, 80) = 50.
  2. 2.Closing balance = 80 − 50 = 30. With 100 of cash, MIN would stop the repayment at 80.

答案50 repaid, 30 left.

Tax with a floor: =MAX(0, pre-tax income) × tax rate

So a loss year pays no tax instead of negative tax.

Common mistakes

常见错误

  • Missing $ anchors, so a filled formula drifts off its inputs.
  • Typing a number into a formula ("=C5*1.1"): it breaks as soon as an input changes.
  • Repaying more debt than is outstanding, or than the cash available.
  • Negative tax in a loss year.
  • Running out of time before the returns: build a rough version end to end first, then refine.
