Build a Retirement Drawdown Sequencing Tool

1. 1

   Position on the education side of the advice line, deliberately

   Software that models scenarios from user inputs and teaches the tradeoffs is planning education; software that tells a specific person 'do this with your money' walks toward regulated investment advice territory. Get securities counsel input on positioning early, write the product voice as 'here is how the scenarios compare and why' rather than directives, and keep the advisor tier (where a licensed human owns the recommendation) as the lane for prescriptive use. This boundary discipline is also the answer to why the incumbent giants have not crushed the niche: careful modeling tools are unglamorous and legally finicky, which is a moat for whoever does the work.

2. 2

   Build the rules engine like it will be audited

   The value is correctness: current federal tax brackets, how different account types are taxed on withdrawal, early-withdrawal penalty rules and their exceptions, required minimum distribution rules (which under current law begin at age 73 for most retirees), Social Security benefit taxation mechanics, and the healthcare-related thresholds (marketplace subsidy cliffs before Medicare, income-based Medicare premium surcharges after) that quietly punish sloppy sequencing. Version the rules by tax year, cite sources inside the app, ship updates when Congress changes the game, and publish your update log; in this category, visible maintenance is marketing.

3. 3

   Make scenario comparison the hero experience

   The user enters their accounts, expected spending, and retirement window, then compares named strategies side by side (taxable-first, proportional, bracket-filling with early Roth conversions) across the metrics that matter: lifetime taxes paid, portfolio longevity, RMD sizes at 80, thresholds crossed in which years. The product's job is making a genuinely hard tradeoff visible and explorable; the 'aha' screenshot of two strategies diverging by six figures of lifetime taxes is what gets shared on retirement forums.

4. 4

   Design for the spreadsheet refugees

   Your core early adopters are the sophisticated DIY retirees who currently maintain terrifying personal spreadsheets and post them in early-retirement communities; they will stress-test your math for free, evangelize when it survives, and demand the assumptions be inspectable (show the year-by-year table, let them override any assumption). Serve them first and honestly, because their approval is the credibility the mainstream retiree waits for.

5. 5

   Price consumer and advisor tiers differently

   Consumers: an annual subscription in the range of $100 to $200 fits the gravity of the decision and the demographic's willingness to pay for durable tools. Advisors and tax practices: per-seat pricing at several times that for client scenario management, white-label reports, and the workflow that turns a two-hour modeling exercise into twenty minutes. The advisor tier likely becomes the revenue center while the consumer tier is the funnel and the brand.

6. 6

   Earn trust through the retirement education ecosystem

   Early-retirement and retirement-planning communities, personal finance educators who cover the drawdown years, CPA and enrolled agent networks, and the content itself: deep, sourced explainers of sequencing concepts that currently live in forum lore. Accuracy is the entire brand, so correct public errors gracefully, publish your methodology, and never let marketing write a number the engine did not produce.
