TOPIC HUB · INVESTING
Investing hub
A job workflow for growth plans: contribution path first, purchasing power second, retirement sizing third. Scenario-test assumptions instead of trusting a single rosy return.
5 calculators · educational planning sketches, not investment advice
Framing: ordered investing playbook (contribution → real return → retirement), not a sky card catalog and not a mortgage PITI workflow.
The job this hub solves
Most investing sketches fail the same way: a single rosy return, no inflation, and no feel for how much you must save each month. This hub walks contribution math, purchasing power, then retirement sizing so the numbers stay honest.
Playbook
Four steps for this job only. Follow in order the first time; jump ahead once the contribution path is settled.
- 01
Lock a contribution path
Start with how much you can add each month and for how long. Compound interest and SIP sketches make the savings rate visible before you argue about returns.
Open compound interest - 02
Convert growth to purchasing power
Nominal balances look strong until inflation is applied. Run the same horizon through the inflation calculator, then compare real return language in the glossary.
Open inflation calculator - 03
Size the retirement target
With a contribution path and a real-return mindset, sketch whether the nest egg covers spending. Treat it as a planning range, not a forecast.
Open retirement calculator - 04
Stress fees and mix (optional)
If the plan depends on a high sticker return, lower the rate a little and re-run. Fee drag and portfolio drift guides explain why small annual gaps compound into large shortfalls.

One caution
These tools are educational planning sketches. They do not recommend securities, predict markets, or replace a fiduciary. Past market returns do not guarantee future results. Keep assumptions visible and re-run when your savings rate or horizon changes.
