Beyond net pay
After Tax Salary vs Cost of Living How to Think
Net pay matters, but it does not automatically tell you what life will feel like in a different place. Costs differ by city, FX snapshots move converted numbers, and your spending mix can change the story.

Quick answers: after tax salary vs cost of living
- Compare net pay and costs together.
- Use cost of living as a separate layer, not a footnote.
- FX snapshots change converted numbers.
- Your spending mix matters most.
Why net pay is not the full story
Two people with the same net can feel different pressure if one has high rent or childcare and the other does not. Some costs are fixed, others are flexible, and local prices shift how far the same net goes.
Costs, currency, and the FX trap
Currency conversion is a snapshot view, and a currency label is not always a conversion. FX moves and can change the destination number. See currency handling basics and the FX snapshot guide.
Simple illustrative example
| Scenario | Net pay (local) | Converted net (illustrative) | Monthly essentials (illustrative) | What to notice |
|---|---|---|---|---|
| A | $4,000 | €4,400 | €3,600 | Plenty left after essentials. |
| B | $4,000 | €4,200 | €4,000 | Same net, less room after higher costs. |
Illustrative only; converted net changes with FX, and costs vary by person.
The checklist for a fair comparison
- Use the same pay frequency.
- Use the same pension percent assumptions.
- Confirm the FX snapshot date.
- Separate essential costs from optional costs.
- Model rent-heavy and rent-light scenarios.
- Model low and high cost cases.
- Rerun when inputs change.
- Do not assume benefits are included.
- Sanity check with your own basket.
- Keep results directional, not definitive.

Common mistakes
- Comparing gross, not net.
- Ignoring FX changes.

- Mixing currencies in one spreadsheet.
- Forgetting one-time relocation costs.
- Expecting exact payslip matching from a simplified tool.
- Assuming taxes shown are complete.
- Drawing a final conclusion from one run.
- Ignoring that lifestyle choices change outcomes.
Privacy and safe handling
- Keep scenario labels generic.
- Export files carefully and avoid personal identifiers.
- Review the Privacy Policy before sharing.
