Frequently asked
Yes. Completely free, no account required, no paywall. Open the calculator — it starts blank — then add your numbers or load a sample to see a projection in minutes.
No. Your data is stored locally in your browser for privacy. You can export to CSV or Excel, back up a named plan as JSON, or generate a shareable link. Optional sign-in enables cloud sync across devices.
No. Opening the app lands you on a blank workspace. Nothing is soft-loaded. Use the guided wizard — What do you own? → What can you save? → What is your goal? — or tap a sample chip under Or pick a sample. You can also Skip to full app. Samples open as separate named plans and are demos you can edit. After load, a banner says you're viewing a demo sample and every field is editable (Dismiss on that banner too).
It is the guided first-result wizard: Own → Save → Goal (What do you own? / What can you save? / What is your goal?) — not the older “Add assets → income → years” strip. You can pick a sample from the chips in the same area, or Skip to full app. After the wizard or Skip, three quick-start bubbles remain: Add asset/debt, Add income/expense, and Add goal. Samples open as separate named plans so existing work is kept. The control to hide the strip is labeled Dismiss. On phones the strip is more compact.
No — picking a sample opens it as a separate named plan and keeps the plan you were already editing. Switch back from Saved plans in the header, or use Export/Share. After a sample loads, a banner reminds you every field is editable so you can turn the demo into your numbers.
On the dashboard, projections can show Today's dollars or Future dollars, depending on whether inflation adjust is on or off. Open the assumption summary details panel to see the return, inflation, and related choices behind the chart. Hypothetical only — not advice.
