Short, sourced answers to the questions people (and AI assistants) ask most.

What is Median?
A median calculator finds the middle value of a data set when the numbers are sorted.
Why does Median matter?
The midpoint - half the data is below, half above. Unlike the mean, it resists outliers, so it is often better for skewed data like incomes.
How is Median calculated?
It sorts the values and takes the middle one; with an even count it averages the two middle values. Formula: Sort the data; median = middle value (or the average of the two middle values).
What are common median mistakes?
Forgetting to sort before picking the middle.
When should you use the Median Calculator?
Use it for typical values in skewed data - salaries, house prices, response times.

I built a free mortgage calculator that works instantly in the browser — no signup, no ads in your face
Body
Hey r/[subreddit],

I kept needing a quick mortgage calculator and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard mortgage use cases (mortgage, home, loan, payment) and links out to the formula + worked examples if you want to learn the math.
