Our Story
Why we built Calculate.cam and how we're helping millions of people navigate the complex world of home financing with confidence.
The Problem We Saw
Buying a home shouldn't feel like solving a math puzzle. Yet millions of people struggle every day with complex mortgage calculations, trying to figure out if they can afford that dream house or whether refinancing makes sense.
We watched friends and family members get overwhelmed by spreadsheets, confused by lender jargon, and make financial decisions based on incomplete information. Some paid too much because they didn't understand their options. Others missed out on homes they could actually afford.
The tools that existed were either too basic (giving you just a payment amount) or too complex (requiring a finance degree to understand). We knew there had to be a better way.
Common Struggles We Heard:
- •"I don't know if I can afford this house payment"
- •"Should I refinance? The math is too confusing"
- •"How much will I actually save with a bigger down payment?"
- •"Is it better to rent or buy in my situation?"
Our Solution
We built Calculate.cam to bridge the gap between complex financial math and real-world decision making.
