Visible assumptions
Rates of return, inflation, tax rates, spending levels, and time horizons should be easy to identify and adjust.
Platform overview
OpenBook Planning is an educational Canadian financial-planning site built around calculators, articles, references, discovery tools, and the CLARITY Framework™. Its purpose is to make planning assumptions easier to see, compare, and discuss.
Financial planning information is often fragmented. Calculators may answer one narrow question, articles may explain concepts without numbers, and important assumptions can be hidden inside simplified outputs. Many people know they need to plan, but not which question to ask first.
OpenBook Planning is built to connect those pieces. Calculators show the numbers, articles explain the concepts, references show the source values, and discovery tools help readers find a useful starting point. The goal is not to produce certainty. The goal is to make the moving parts easier to understand.
The platform is built around a simple principle: financial planning should be explainable. A useful planning tool should make the inputs visible, show what the output depends on, and avoid presenting a modelled result as a personal recommendation.
Rates of return, inflation, tax rates, spending levels, and time horizons should be easy to identify and adjust.
Outputs should be understandable enough to support learning, review, and better planning conversations.
The site is designed to clarify concepts and tradeoffs, not to push users toward products or decisions.
Financial planning is already complex. The interface should reduce noise, not add urgency or pressure.
The CLARITY Framework™ is a high-level framework for organizing financial planning topics. It is not a rigid methodology or sales process. It helps group financial questions into seven connected pillars so users can see how one planning decision may affect another. Explore The CLARITY Framework™.
OpenBook Planning uses colour as an organizing signal. The coloured accents on calculator pages, articles, references, and CLARITY pillar pages usually indicate the primary CLARITY pillar connected to that page, such as Cash Flow, Liabilities, Assets, Retirement Readiness, Insurance and Risk, Tax Optimization, or You.
These colours do not rank importance, indicate risk level, imply a recommendation, or suggest that one topic is more suitable than another. They are intended to help readers recognize related planning areas more quickly. Some tools may also use softer background colours inside input, result, or reference sections to group related information for easier scanning.
Colour is not intended to be the only way information is communicated. Page titles, headings, labels, links, and explanatory text remain the primary way the site identifies content and context.
OpenBook is designed so a reader can move between questions, tools, explanations, and source values. Someone might start with a broad planning concern, use the calculator discovery guide to find relevant tools, review the reference values behind an assumption, and then read an article that explains the concept in plain language.
If you have a specific question, start with the calculator discovery guide.
If you want to learn a topic first, browse the article library.
If you want to check a rule, limit, threshold, or source value, use the reference library.
OpenBook is designed to be lightweight and privacy-conscious. Calculators are intended to run in the browser where practical, and the site does not need personal financial records to provide educational estimates.
OpenBook may use privacy-conscious site analytics, when enabled, to understand broad usage patterns, such as which pages, calculators, and resources are useful. These analytics are not intended to collect calculator input values, calculator results, personal financial details, generated briefing content, or free-text financial information.
Where analytics consent is requested, visitors can continue using the site without allowing analytics.
OpenBook is available in English, French, and Simplified Chinese. Across languages, our goal is the same: explain financial planning concepts clearly, preserve important Canadian terms, and make the educational limits of each article or calculator visible.
OpenBook Planning is educational information only. It is not financial, tax, legal, accounting, investment, retirement, estate, insurance, mortgage, or lending advice.
Calculators simplify reality. They may omit important details such as tax brackets, account rules, eligibility requirements, investment fees, market volatility, sequence-of-returns risk, legislative changes, estate outcomes, and personal circumstances. Results should be treated as learning tools and planning prompts, not instructions.
Assumptions matter. A small change in inflation, returns, tax rates, spending, timing, or benefit assumptions can materially change an output. The site is designed to help make those sensitivities more visible.
OpenBook Planning is maintained as an educational resource. Over time, articles, calculators, references, and translations are reviewed so that assumptions stay visible, source links remain useful, and explanations stay clear.
The aim is not to make planning look more certain than it is. The aim is to make planning questions easier to understand, compare, and revisit.
