Looking for your next SaaS project with high viral potential and low technical overhead? This is it.
The Market Gap: Standard salary tools like Glassdoor or Salary.com stop at tax brackets. They completely ignore the 'Cost of Working'—parking, tolls, fuel, and the most valuable asset: time. With the aggressive 'Return to Office' push, millions of professionals are accepting 'raises' that actually result in lower monthly disposable income.
The Validation: This isn't just a theory; it's a proven pain point. A recent viral Reddit thread in r/careerguidance (500+ upvotes, 220+ comments) featured a user whose $10k raise was instantly swallowed by $530/month in new office expenses. The community response was massive, with users begging for a 'revenue vs. profitability' tool for their careers.
The Solution & Unique Angle: NetPay Calc is a decision-support tool that goes beyond the paycheck. By integrating mapping APIs and real-time data for gas and parking, it provides a 'True Net Pay' comparison between two jobs. The killer feature? A 'Time Value' calculation that shows users exactly what their hourly rate becomes once commute hours are factored in.
The Opportunity: This is an ideal build for an indie hacker or small team:
Low Complexity: The core product is a sophisticated calculator with existing API integrations (Google Maps, IRS Tax data).
High Virality: The 'Your raise is a lie' narrative is tailor-made for LinkedIn and Reddit career advice content.
Clear Monetization: A freemium model where users pay for advanced tax optimization or unlimited scenario comparisons.
This is a validated problem waiting for a builder to execute.
