Money & Life Guides
Our calculators give you the number. These guides give you the understanding behind it: the rules lenders use, the math retirement accounts run on, and the strategies that actually work, each explained with real worked numbers.

How Much House Can I Afford?
The 28/36 rule lenders use, applied step by step with real incomes, plus what the rules leave out and how your down payment changes the answer.
Roth vs. Traditional IRA: The Math That Decides It
Pay tax now or later? A worked 30-year example shows exactly when each account wins, and why the answer comes down to one comparison.
Debt Avalanche vs. Snowball: Which Pays Off Faster?
Two payoff strategies run against the same three debts with real numbers, so you can see the interest saved and the psychology traded away.
VA Disability Ratings, Explained
Why 50% plus 30% is not 80%: the VA's combined-ratings formula worked through a full example, plus the bilateral factor in plain English.
What Is a Good GPA?
The 4.0 scale, what counts as good for jobs versus grad school, weighted versus unweighted, and the math of raising your GPA before you graduate.
Why guides, not just calculators
A calculator answers "what is the number?" A guide answers "what should I do with it?" Every article here pairs with one of our free calculators: run your own numbers in the tool, then come back here to understand what the result means and what to do next. No signup, no paywall, no fluff.
Each guide is built the same way: plain language first, real worked examples with every step shown, and a short FAQ answering the questions people actually ask. If a guide ever contradicts your situation, trust a qualified professional over a web page, but the math here will still be right.
