Financial Tools Built by People Who've Been There

We created FinanceCalc after seeing too many people get bad advice from banks who profit from maximizing loan amounts—not helping you buy smart.

Why We Built This

The $150,000 Mistake That Started Everything

In 2018, I was a 29-year-old loan officer at Wells Fargo making $92,000 a year. Ironically, I helped other people get mortgages—but when it came to my own purchase, I made the exact mistake I now help people avoid.

I got approved for a $475,000 mortgage. The bank said "you can afford it." I trusted them. After all, they're the experts, right?

I bought the house. Within 18 months, I was drowning.

Here's what actually happened:

✘ Living paycheck to paycheck despite a "good" salary
✘ Emergency $8,000 roof repair wiped out my entire savings
✘ Couldn't afford to go out with friends, travel, or save for retirement
✘ Constant stress about every unexpected expense
✘ Relationship strain—my girlfriend and I fought about money constantly

I was what financial planners call "house-poor." My house looked impressive from the outside. Inside? I was eating ramen and skipping social events because I couldn't afford a $40 dinner.

In 2020, when my HVAC died ($6,500 replacement) and I had to put it on a credit card, I realized: the bank approved me for a loan that maximized THEIR profit, not my financial health.

I sold the house later that year. After closing costs, realtor fees, and market timing, I lost $45,000 on a home I owned for just 2.5 years.

Lesson learned the expensive way: Banks maximize loan size to make more interest. You need to use conservative affordability calculations, not aggressive bank maximums.

FinanceCalc was born from that $150,000 mistake (loss on sale + 2.5 years of being house-poor). These calculators use realistic, conservative numbers—the 25% rule, not the bank's 28-36% rule.

My goal: Help you avoid the mistake I made.
