What is "TruthCost"?

"I didn't overspend this month, so why aren't my savings growing?"
"I'm in the black every month, but my bank account doesn't reflect it."
There is a structural reason for this feeling.

TruthCost Monthly Living Expenses + Subscriptions & Irregular Costs + Asset Depreciation

"TruthCost" (Total Cost of Ownership) is the true cost of maintaining your lifestyle. It includes not just your rent and groceries, but also irregular expenses (like next year's vehicle inspection) and the prorated monthly cost of durable goods you will inevitably have to replace—like your car or smartphone.
These costs don't show up on a standard monthly budget, but as an economic reality, you are paying for them right now.

The Gap

"Expenses" and "Costs" Are Not the Same

For example, let's say you buy a $30,000 car and plan to use it for 5 years.

Standard Budget (Cash Flow)
TruthCost (Actual Financial Burden)
PurchaseMonth 2Month 3Month 4Month 5Month 6
On a standard budget, it looks like a massive expense occurs only in the month of purchase, with nothing happening in the following months. However, the car is steadily degrading, and you will need to replace it in 5 years.
That future cost doesn't just hit you all at once; it is quietly accruing every single month.
If you ran a $500 surplus every month, you would save $30,000 over 5 years. But if you have to buy a new car for $30,000 at the end of those 5 years, your entire savings will be wiped out. If you own a car now, this replacement cycle is highly predictable.
VS Standard Budget

What's the Difference?

Here is how the two metrics view "the month after buying a car."

Standard Budget
Includes
Rent, food, utilities, standard subs, etc.
Timing of Impact
Only in the month the cash is paid.

Recorded in Budget?
Yes
TruthCost

Base expenses + Future replacement costs
Timing of Impact
Continuously, every month.

No (A hidden fixed cost)
The Blind Spot

Corporations Calculate This Naturally

In corporate accounting, it is standard practice to record the cost of capital investments as "depreciation" in monthly expenses. A company doesn't expense a new building or machine all at once in the month it was purchased. They divide the cost over its useful life and expense it gradually.

The exact same thing is happening in your personal life. Your smartphone, car, and refrigerator don't lose their cost the moment you buy them; they are degrading the entire time you use them. The concept of calculating this "asset depreciation" simply hasn't been mainstream in personal finance—until now.

In Numbers

Let's Look at the Numbers

iPhone 16 Pro
Purchase Price $1,200
Lifespan 3 Years = 36 months
────────────────────
True Monthly Cost $33 / month
Personal Car
Purchase Price $30,000
Lifespan 5 Years = 60 months
────────────────────
True Monthly Cost $500 / month
These two items alone represent $533 a month. That is an amount completely missing from your standard budget book.
Our Position
If your income falls below your TruthCost,
it is structurally impossible to grow your savings.

From there, whether you choose to increase your income or restructure your lifestyle costs is entirely up to you.

TruthCost.calc is simply a tool designed to calculate the raw "numbers" needed for you to make that rational decision.
