The story
Hi, I’m JX.
CalmExpense started as my own spreadsheet. I built it because I wanted a calm, private way to see where my money was going, without handing my financial life over to a bank feed or an app I did not control.
How it started
Fresh out of college, I got my first real paycheck and felt like I could finally spend. So I did. Mostly on dining out, deliveries, and whatever else felt like a reward after years of studying. It did not feel reckless at the time. It just felt normal.
But a few months in, I checked my savings and they had barely moved. Lifestyle inflation had crept in without me realising it. I was earning more than I ever had, and somehow still not getting ahead.
That was the moment I decided to track every single dollar. Not because I wanted to be frugal, but because I wanted to understand where the money was actually going.
Finding the right tool
I tried manual tracking first. It works when you have 10 transactions a month, but once the list grows to hundreds, updating a spreadsheet by hand every day becomes a chore you quietly stop doing.
I looked at budgeting apps too, but they all wanted my bank login or access to read my transactions. I was not comfortable handing over that kind of data to a third party. My finances, my privacy.
Then I discovered that most banks let you download your transactions as a CSV file. The raw data was all there, it just needed cleaning and organising before it became useful. That cleanup takes some technical know-how, which happened to be something I was comfortable with. So I built a pipeline: download, clean, and push the data into a dashboard that updates itself.
I set it up for my girlfriend too. Watching her get the same clarity from her own spending data was the moment I realised this could help more people. What started as a side project for the two of us became something I wanted to share.
Small, recurring spends add up
The first thing my spreadsheet caught was Shopee. Over two years I had spent $4,777 there, about $149 a month, without really noticing. Then November 2023 showed a $719 spike in a single month. That was the wake up call. So I gave myself one rule: anything big sits in the cart for 24 hours before checkout. Most of the time the urge is gone by morning. I call it my 24 hour cart quarantine, and it stuck.
But tracking is not just about cutting back. In 2025 I put $1,830 into Genki Sushi, about $152.50 a month, Premium membership and all. There was one day I went for both lunch and dinner. My cheapest meal came to $0.24 after rebate points. I spend around $836 a month on food total, because a high protein diet is how I lost 25kg and I am not giving that up.
Good budgeting was never about spending less for me. It is about spending right. On the things I actually care about, and quietly trimming the things I do not.
100k by 30
Tracking spending was only half the picture. I also tracked what I was putting away. I started dollar cost averaging at $1,000 a month, then raised it to $2,500 once I had the confidence and the cash. By 30 I had $102,870 invested.
The number felt good, but the real lesson was that money is less about the figure and more about the habits and mindset you build getting there. The book “Die With Zero” put words to something I already felt. Money is meant to be used well, at the right time, not just piled up and left.
Saving for the future with my partner
These days the tracking is not just about me. My partner and I are saving toward the big things ahead: a BTO flat, a wedding, and a honeymoon we actually want to enjoy. None of that happens by accident. It happens because we know our numbers and we plan around them on purpose.
That is really why CalmExpense exists. When you can see where your money goes, saving for a milestone stops feeling like a vague hope and starts feeling like a plan you are already on top of. The tracking looks after itself in the background, so we get to spend our actual time and attention on the things that matter to us.
