# What is Technical Debt?

*Development · Last updated: November 5, 2026*

The additional cost and complexity generated over time by temporary solutions chosen in software to achieve quick results.

## Overview

Technical debt refers to the negative effects that low-quality code, written by taking shortcuts in the early stages of a project, will create in the future. Although it saves time initially, it makes system maintenance difficult over time and slows down the addition of new features. If not cleaned regularly, it makes the project unsustainable.

***Analogy:** It is similar to shopping with a credit card. You meet your immediate need, but you have to pay it back with interest.*

## How it works

Developers implement the fastest working solution instead of the most perfect architecture within limited timeframes. Over time, these temporary solutions accumulate and lead to chaos in the codebase. Developers pay off this debt by performing refactoring.

## Where it is used

It is a situation encountered in fast-growing startups, projects with tight deadlines, and long-lived software systems.

## Commonly confused with

It should not be confused with a software bug. While a bug is the system working incorrectly, technical debt is the situation where the system is poorly designed even if it works correctly.

## Questions and answers

**Can technical debt be completely prevented?**

It is almost impossible to prevent it completely, but it can be kept under control with good architecture and regular code cleaning.

**How is technical debt paid off?**

It is paid off through refactoring efforts that improve the structure of the code without changing its functionality.
