About WorthCrunch
Run the numbers before you spend.
WorthCrunch builds free, no-nonsense calculators for big-ticket money decisions — starting with whether home solar actually pays off in 2026. The internet is full of "calculators" that hide their assumptions, gate results behind your email, or quietly run on outdated tax rules. We do the opposite.
What makes our calculators different
- Every assumption is visible and editable. If you don't trust an input, change it and watch the result update.
- No email, no sign-up, no upload. Everything runs in your browser. We can't see your numbers.
- Kept current. Our solar calculator reflects the 2026 expiry of the federal residential tax credit — something many older tools still get wrong.
How we stay free
When useful, we may earn a commission if you choose to request quotes from a partner — at no cost to you. These links are clearly marked. Recommendations are never pay-to-play; the math always comes first.
A note on accuracy
Our tools give transparent estimates, not engineering quotes or financial advice. Always confirm with itemized local quotes and a professional before making a large purchase. Back to the solar calculator →
