Guides

Borrowing, with the numbers

Each guide is built around a calculation you can run on your own figures, not general advice you have read elsewhere.

When refinancing actually saves money

A lower monthly payment and a lower total cost are different things, and a refinance often delivers only one. Work out your break-even month including closing costs — and see the case where dropping your rate by more than a point still costs you $44,000.

What your credit score actually costs, in dollars

The score is a price tag, not a goal. Translate the tiers into money on your own loan size and term, and find out whether waiting three months to improve it is worth it — because sometimes it clearly is not.

Shopping for a car loan rate

Where to get pre-approved before you walk into a dealership, how dealer financing markups work, and how to keep the conversation about the price of the car rather than the size of the payment.

Paying off student loans faster

Which extra payments do the most work, why the timing of them matters more than the size, and the one situation where paying extra is the wrong move entirely.

Start with a calculator instead

If you already know what you are borrowing and just want the numbers, the calculators are faster than reading. Each one handles the arithmetic specific to its category rather than treating every loan the same.

Loan calculator

Any fixed-rate loan: payment, interest, amortization.

Auto loan

Plus the month you stop owing more than the car is worth.

Personal loan

True APR once the origination fee is folded in.

Student loan

What interest adds before repayment even starts.

These guides are educational and are not financial advice. Figures used in examples are illustrative rather than quotes. For decisions that matter, your lender's disclosure documents and a licensed professional are the right sources.
