CFP Investment Planning Cheat Sheet (2026): Key Formulas, Ru

You've probably heard the CFP exam is less about raw memorization and more about application. That's true, but for the Investment Planning section (Principal Knowledge Topic 3), there's a unique trap: relying too much on the provided formula sheet. While the CFP Board gives you a list, it won't explicitly tell you when to use which formula, or which critical tax thresholds and investment rules you need to have cold. That's where candidates often stumble, wasting precious time fumbling through options when they should be executing.

This cheat sheet distills the essential formulas, rules, and frameworks for CFP Investment Planning (Principal Knowledge Topic 3) into an actionable guide. It’s designed not just for recall, but to sharpen your judgment on how to approach investment-related questions, helping you think like the examiner and avoid common pitfalls.

Investment Planning at a Glance (CFP Board Principal Knowledge Topic 3)

The Investment Planning section (often referred to as CFP3 in study programs) is a cornerstone of the CFP exam, typically accounting for 17% of the exam questions. This means roughly 25-29 questions will test your knowledge in this area. It's a critical component, reflecting the core of what many financial planners do daily.

This section doesn't just ask you to recall formulas; it demands you apply them to real-world client scenarios. You'll be tested on your ability to:

Analyze investment vehicles: Stocks, bonds, mutual funds, ETFs, alternative investments.
Understand risk and return: Standard deviation, beta, alpha, Sharpe ratio, Treynor ratio, Jensen's alpha.
Construct portfolios: Asset allocation, modern portfolio theory (MPT), capital asset pricing model (CAPM).
Evaluate performance: Time-weighted vs. dollar-weighted returns.
Navigate tax implications: Capital gains/losses, dividends, wash sales, passive activity losses, alternative minimum tax (AMT).
Develop investment policy statements (IPS): Objectives, constraints, benchmarks.

The highest-weight areas often involve calculating risk-adjusted returns, understanding the taxation of various investment vehicles, and applying portfolio management theories. While formulas are provided, understanding their inputs, outputs, and underlying assumptions is what separates passing candidates from those who struggle. You must understand the "why" behind the "what."

Must-Know Formulas, Rules, and Frameworks

Memorizing a formula is one thing; knowing when and how to deploy it is another. Here are the core concepts you absolutely need to master, along with key thresholds and shortcuts.

Core Investment Formulas

While the CFP Board provides a formula sheet, you need to know what each variable represents and the context for its use.

Standard Deviation (SD): A measure of total risk.
Formula: $\sqrt{\sum \frac{(R_i - \bar{R})^2}{N-1}}$ (for sample standard deviation)
Key Insight: Higher SD means greater volatility. Often used with historical data.
Beta ($\beta$): A measure of systematic (market) risk.
Formula: Covariance (Asset, Market) / Variance (Market)
Key Insight: $\beta > 1$ means more volatile than the market; $\beta < 1$ means less volatile. The market's beta is 1.
Capital Asset Pricing Model (CAPM): Calculates required rate of return.
Formula: $R_e = R_f + \beta(R_m - R_f)$
Key Insight: $R_m - R_f$ is the market risk premium. This is a foundational model for determining the appropriate return for an asset given its systematic risk.
Sharpe Ratio: Measures risk-adjusted return (excess return per unit of total risk).
Formula: $(R_p - R_f) / \sigma_p$
Key Insight: Higher Sharpe ratio is better. Uses standard deviation, so it's appropriate for diversified portfolios.
Treynor Ratio: Measures risk-adjusted return (excess return per unit of systematic risk).
Formula: $(R_p - R_f) / \beta_p$
Key Insight: Higher Treynor ratio is better. Uses beta, so it's appropriate for well-diversified portfolios (where unsystematic risk is largely diversified away).
Jensen's Alpha ($\alpha$): Measures the excess return above what CAPM predicts.
Formula: $R_p - [R_f + \beta_p(R_m - R_f)]$
Key Insight: A positive alpha means the portfolio outperformed the market on a risk-adjusted basis. A negative alpha means underperformance.
Tax-Equivalent Yield (TEY): Calculates the taxable yield equivalent to a tax-exempt yield.
Formula: Tax-Exempt Yield / (1 - Marginal Tax Rate)
Key Insight: Used to compare municipal bonds with taxable bonds. Always compare marginal rates.

Critical Investment Rules and Thresholds (2026 Considerations)

These are often tested implicitly and demand immediate recall.

Capital Gains/Losses:
Short-term: Assets held for one year or less, taxed at ordinary income rates.
Long-term: Assets held for more than one year, taxed at preferential long-term capital gains rates (0%, 15%, or 20% for 2026, depending on income brackets).
Netting Rule: Capital losses first offset capital gains of the same type (short-term against short-term, long-term against long-term), then against other types.
Maximum Deduction: You can deduct up to $3,000 of net capital losses against ordinary income per year. Any excess is carried forward indefinitely.
Wash Sale Rule:
Rule: If you sell a security at a loss and buy a "substantially identical" security within 30 days before or after the sale date (a 61-day window), the loss is disallowed.
Impact: The disallowed loss is added to the cost basis of the newly acquired security. This rule prevents investors from creating artificial losses for tax purposes.
Dividend Taxation:
Qualified Dividends: Generally taxed at preferential long-term capital gains rates (0%, 15%, or 20% for 2026). Requirements include holding the stock for a specified period (typically 60 days during a 121-day period surrounding the ex-dividend date).
Non-Qualified (Ordinary) Dividends: Taxed at ordinary income rates.
Passive Activity Losses (PALs):
Rule: Losses from passive activities (e.g., rental real estate, limited partnerships) can generally only offset passive income.
Exception (Real Estate): For active participation in rental real estate, you can deduct up to $25,000 of PALs against non-passive income, subject to a phase-out. This phase-out begins when modified adjusted gross income (MAGI) exceeds $100,000 and is fully phased out at $150,000.
Margin Requirements:
Initial Margin (Regulation T): Currently 50% for stocks (set by the Federal Reserve).
Maintenance Margin: Typically 25% of the market value (set by FINRA), but brokers can require higher.
Crucial: Know how to calculate equity, market value, and determine when a margin call occurs.

Worked Example: Capital Loss Carryforward

Let's walk through a common tax scenario that trips up many candidates.

Scenario: Sarah, a single filer, had the following investment activity in 2026:

Short-term capital gain: $10,000
Short-term capital loss: $15,000
Long-term capital gain: $20,000
Long-term capital loss: $30,000
Ordinary income (after all other deductions): $90,000

Question: What is Sarah's net capital loss deduction against ordinary income and her capital loss carryforward to 2027? Step-by-Step Walk-through:

Net Short-Term Capital Gain/Loss:
$10,000 (STCG) - $15,000 (STCL) = ($5,000) Net STCL
Net Long-Term Capital Gain/Loss:
$20,000 (LTCG) - $30,000 (LTCL) = ($10,000) Net LTCL
Overall Net Capital Gain/Loss:
($5,000) Net STCL + ($10,000) Net LTCL = ($15,000) Overall Net Capital Loss
Deduct against Ordinary Income:
The maximum deduction against ordinary income is $3,000 per year.
Sarah deducts $3,000 from her $90,000 ordinary income.
Calculate Capital Loss Carryforward:
Overall Net Capital Loss: ($15,000)
Less: Deduction against ordinary income: ($3,000)
Capital Loss Carryforward to 2027: ($12,000)

Common Wrong Answer & Why it's Tempting: A common mistake is to assume you can deduct the entire $15,000 loss, or to incorrectly net short-term losses against long-term gains before fully netting within their own categories. Another trap is to forget the $3,000 annual limit. Candidates might also mistakenly believe the carryforward expires. The key is to follow the netting rules precisely and remember the annual deduction limit and indefinite carryforward.

Common Traps and Test-Day Reminders

Even with a solid grasp of the material, the CFP exam is designed to test your application under pressure. Be aware of these common pitfalls:

Mixing Up Risk-Adjusted Return Ratios:
Trap: Confusing Sharpe, Treynor, and Jensen's Alpha.
Reminder:
Sharpe: Uses Standard Deviation (total risk), best for undiversified or total portfolio comparisons.
Treynor: Uses Beta (systematic risk), best for well-diversified portfolios.
Jensen's Alpha: Measures excess return over CAPM, also uses Beta.
Always check if the question implies a diversified or undiversified context.
Ignoring Tax Implications:
Trap: Calculating returns or portfolio values without considering taxes on capital gains, dividends, or interest.
Reminder: The CFP exam is about financial planning, not just finance. Taxes are almost always a factor. Pay attention to client's income level (for capital gains rates), holding periods (short vs. long-term), and whether the investment is in a taxable or tax-advantaged account.
Confusing Bond Duration with Maturity:
Trap: Using maturity as the primary measure of interest rate risk.
Reminder: Duration is the true measure of a bond's price sensitivity to interest rate changes. A bond with a longer duration is more sensitive. Maturity is merely when principal is repaid.
Calculation Mistakes:
Order of Operations: Don't rush. Use your calculator properly.
Annualizing: Ensure all rates (e.g., holding period returns) are annualized if the question requires it.
Nominal vs. Real Returns: If inflation is mentioned, consider whether the question asks for a nominal (stated) or real (inflation-adjusted) return. Use the Fisher Equation: $(1 + \text{Nominal}) = (1 + \text{Real}) \times (1 + \text{Inflation})$.
Timing Pitfalls:
Not Reading Carefully: A single word ("after-tax," "pre-tax," "real," "nominal," "short-term," "long-term") can change the entire answer.
Spending Too Long: If a calculation is taking too long, mark it, make an educated guess if needed, and move on. You can always revisit if time allows. Don't let one complex question derail your pace. Remember, you have approximately 1.8 minutes per question on the exam.

Mnemonics and Memory Aids

Mnemonics aren't just for rote memorization; they're hooks that help you recall complex lists or processes quickly under pressure.

Investment Policy Statement (IPS) Components: Think of the IPS as a roadmap for a client's journey. What does a good roadmap need?
Client Information: Who is this for? (Goals, Risk Tolerance, Time Horizon)
Investment Objectives: Where are we going? (Return requirements, liquidity needs)
Investment Constraints: What are the roadblocks? (Time Horizon, Liquidity, Taxes, Legal/Regulatory, Unique Circumstances) - "TLTU" for Taxes, Legal, Time, Unique.
Investment Strategy: How will we get there? (Asset allocation, permitted investments)
Performance Measurement: How will we know if we arrived? (Benchmarks, review process)
Types of Investment Risk:
"PURR MINE" (or some variation) is common:
Purchasing Power Risk (Inflation)
Unsystematic Risk (Business, Financial)
Reinvestment Rate Risk
Regulatory Risk
Market Risk (Systematic)
Interest Rate Risk
Non-Market Risk (Liquidity, Political, Social)
Exchange Rate Risk
Key distinction: Understand which risks are diversifiable (unsystematic) and which are non-diversifiable (systematic). Beta measures systematic risk.
What is Worth Memorizing Cold:
The $3,000 capital loss deduction limit and indefinite carryforward.
The 61-day wash sale window (30 days before, day of sale, 30 days after).
The phase-out range for the $25,000 passive activity loss deduction for active real estate participants ($100,000 - $150,000 MAGI).
The primary differences between Sharpe, Treynor, and Jensen's Alpha.
The basic components of the CAPM formula.

Building your own memory hooks often works best because they're tailored to how your brain makes connections. When you encounter a list or a sequence, try to create an acronym, a silly phrase, or visualize the concepts.

Frequently asked questions

Is Investment Planning CFP3 or CFP5?

Investment Planning is Principal Knowledge Topic 3, often referred to as CFP3 in study programs. CFP Board's Principal Knowledge Topic 5 covers Retirement Savings and Income Planning. It's a common point of confusion, so ensure your study materials align with Topic 3 for investments.

What is the most challenging part of the CFP Investment Planning section?

Many candidates find the quantitative aspects, particularly the nuances of risk-adjusted return calculations (Sharpe, Treynor, Jensen's Alpha) and the complex tax implications of various investment vehicles, to be the most challenging. Understanding when to use which formula and how taxes impact client decisions requires strong judgment.

How many hours should I study for CFP Investment Planning?

Given that Investment Planning accounts for 17% of the CFP exam, dedicating approximately 40-50 hours specifically to this section out of the recommended 250-300 total study hours is a good guideline. This includes time for reading, reviewing formulas, and extensive practice questions.

Are investment formulas provided on the CFP exam?

Yes, the CFP Board provides a formula sheet during the exam. However, it's crucial to understand what each variable in the formulas represents and, more importantly, when and how to apply each formula correctly to different client scenarios. Relying solely on the sheet for understanding is a common mistake.
