What this cash-secured put yield calculator is showing you
Selling cash-secured puts is a conservative options strategy where you get paid cash today for agreeing to buy high-conviction shares at a discounted target strike price if the stock drops. Purpose-built for practical decision-making, the Cash-Secured Put Yield Calculator provides quantitative clarity on this financial problem by transforming raw input assumptions into structured, actionable projections. Calculations reflect Australian Taxation Office (ATO) Stage 3 personal tax brackets, the 2.0% Medicare Levy, and statutory Superannuation Guarantee rates.
Calculations are performed using the mathematical model Annualized Return on Collateral = (Premium / Strike Price) * (365 / DTE) * 100. Effective Entry Price = Strike Price - Premium.. In this computation, Current stock trading price ($/share) establishes the baseline scale, while parameters such as Put option strike price ($/share) determine the progression over time. Adjusting these values allows you to observe how incremental changes directly influence your final outcome.
Mathematical Model
Annualized Return on Collateral = (Premium / Strike Price) * (365 / DTE) * 100. Effective Entry Price = Strike Price - Premium.

How to interpret your results
Distinguish between your marginal tax bracket and your effective overall tax rate. The effective rate represents the actual percentage of gross income owed in taxes.
Identify pre-tax deductions, allowable retirement contributions, and eligible tax credits that can legally reduce taxable base income before formal filing.
- ✓ Review standard deduction versus itemized deduction thresholds to ensure you claim the optimal filing status.
- ✓ Utilize tax-advantaged accounts (such as 401(k), IRA, or HSA) to legally reduce taxable gross income where eligible.
- ✓ Consult official tax authority documentation or a qualified CPA for complex multi-jurisdiction or business tax scenarios.

Cash-Secured Put Yield Calculator Assumptions & Planning Boundaries
This calculator executes deterministic mathematical models based on Annualized Return on Collateral = (Premium / Strike Price) * (365 / DTE) * 100. Effective Entry Price = Strike Price - Premium.. It assumes that entered parameters—such as Current stock trading price ($/share) and associated rates—remain constant throughout the evaluated period without unmodeled mid-cycle adjustments.
In real-world financial environments, factors including macroeconomic interest rate shifts, localized tax regulations, loan origination fees, closing costs, and inflation variability may cause actual outcomes to differ from theoretical calculations. These figures should be utilized as an analytical planning baseline rather than a legally binding quotation.
Key Factors to Review:
- • Statutory bracket baseline: Estimates use current statutory brackets and standard deductions without personalized tax adjustments.
- • Jurisdictional variance: State, provincial, local, or municipal taxes may alter total tax liability compared to federal baselines.
- • Deduction eligibility: Individual tax positions depend on verified receipts, exemptions, and formal tax authority guidelines.
Frequently Asked Questions
How does selling cash-secured puts allow you to earn double yield? ▼
While reserving cash collateral to secure the put strike price (e.g. $11,000 for a $110 strike), most modern brokerages permit the collateral to sit in Treasury bills or money market funds earning 4-5% interest while simultaneously collecting put option premiums.
What is the risk of selling a cash-secured put? ▼
If the underlying stock drops drastically (e.g. to $70 due to catastrophic news), you are legally obligated to buy the shares at the $110 strike price, resulting in a substantial unrealized loss offset only by the $2.20 premium collected.
