Three-step workflow

1. Start with a regional page

Use country/state shortcuts first so assumptions and fields match your situation.

2. Compare at least two scenarios

Run a base case and a stress case; decisions are better when you compare outcomes side by side.

3. Use output for planning, not filing

Use these calculators for budgeting and comparisons, then verify final numbers with official sources.

What users ask first

Are calculations done on the server?

No. Core calculator logic runs in-browser so results are computed locally on your device.

Can I use country or state-specific pages directly?

Yes. Each regional page preloads local context so you can start with the right assumptions immediately.

Should I rely on this for official filing or lending paperwork?

Use these results for planning and comparison. For legal or filing accuracy, confirm with official sources.
