A missed payment starts a clock: fees, credit reporting, charge-off and collections arrive in stages. This guide follows that clock across credit cards, auto loans, mortgages and federal student loans. It separates what federal rules set from what the loan contract and state law decide: the card late-fee safe harbor after the 2024 rule was struck down, the 30-day reporting convention, the day-36 and day-45 mortgage servicer contacts, and the 270-day student loan default point. It also says who each rule covers. A worked example prices a $350 auto payment missed for one, two and three months under a hypothetical 5% late fee, so the cost of catching up is visible in dollars. A short checklist covers what to ask the servicer and what to keep in writing.

A co-signer owes the full loan if the borrower stops paying, and the debt counts against their own borrowing. This guide shows what the federal Notice to Cosigner says, how a $25,000 auto loan moves a co-signer's debt-to-income ratio from 22.7% to 32.3%, and why the common claim that a co-signer's available credit drops by the loan amount is wrong. It also covers how mortgage underwriting can treat co-signed debt, what Chapter 13 bankruptcy does and does not do for a co-signer, why release is hard to get, and what the CFPB found about private student loans when a co-signer dies. It closes with a checklist to run through before signing anything.
A $240 shortfall costs $6.87 on a true 0% offer and $380.56 on a deferred-interest one. Both offers are advertised as "no interest", but they treat an unpaid balance in opposite ways. This guide separates true 0% intro APR from deferred interest, explains where each tends to appear and how buy now, pay later fits in, and works through a $2,400 purchase and a $5,000 balance transfer with the arithmetic shown. It also sets out the federal card rules that matter during a promotion: the six-month minimum, the 60-day late exception and how extra payments are allocated. It closes with a short checklist for reading the terms before accepting an offer.
A variable loan rate is an index plus a margin within caps, so its worst-case payment can be known in advance. The comparison runs on October 2026 figures: a 7.40% Freddie Mac average for 30-year fixed mortgages, 30-day average SOFR near 3.86%, and a 7.00% prime rate that has tracked 3 points above the Fed's target ceiling since 2008. A $400,000 7/6 ARM is set against a fixed loan under two paths, rates unchanged and the 5/1/5 cap ceiling, and the worst case raises the payment 47% at the first reset. Also covered: what the Regulation Z notices say and when they arrive, how a $50,000 prime-based HELOC moves when prime shifts 2 points, and the questions to settle before choosing either structure.
On a $350,000 30-year loan at 7.40%, principal first outweighs interest only in month 249. Amortization is the schedule that splits each fixed loan payment between interest and principal, and the split follows one formula: interest is the monthly rate times the remaining balance, and principal is whatever is left. The guide builds full schedules for $350,000 at Freddie Mac's October 8, 2026 averages for 30- and 15-year loans, shows the balance after 5 and 10 years, corrects the idea that a 15-year term doubles the payment, and explains negative amortization, interest-only periods, ARM resets, car and student loans, credit cards, escrow and the $750,000 mortgage interest limit.
On Fannie Mae's January 2026 grid, a 680 score instead of 740 added $3,063 in fees to a $350,000 mortgage. Lenders turn a credit score into a price through risk-based pricing: score bands and the size of the down payment set fees, which reach the borrower as points or a higher rate. This guide reads selected cells of Fannie Mae's price grid, shows how the same fee looks when it is built into the rate, and prices a half-point rate gap on a 30-year loan at about $120 a month. It also covers which score models mortgage lenders may use, FHA's 580 and 500 cutoffs, why car loans and cards have no public score tiers, the notices federal law requires, and why paying a card before the statement date changes the balance the bureaus see.
A 6.5% mortgage with $6,000 in lender fees shows a 6.70% APR, yet repaid in five years it costs about 6.99%. The interest rate prices only the interest; the annual percentage rate folds in the other charges federal law classes as finance charges, such as points, origination fees, broker fees and mortgage insurance, and spreads them over the full term. This guide sets out which fees Regulation Z puts in and leaves out, solves the APR for a mortgage and for a $10,000 personal loan with a 5% fee, and shows why the same fees raise the APR more on shorter loans. It also explains why credit card APRs leave fees out, how a 24.99% card rate becomes daily interest, how APR differs from APY, and what to check on a Loan Estimate before comparing offers.
Secured loans usually cost less because the lender can take property, which changes what a default costs. The comparison starts with Federal Reserve rate data from August 2026, when bank personal loans averaged 11.90% and 60-month new-car loans 7.54%, and turns those rates into payments on a $10,000, three-year loan. It then sets out what each type puts at risk if payments stop: repossession or foreclosure on one side, a lawsuit and wage garnishment capped by federal law on the other. Credit reporting, Chapter 7 and Chapter 13, and a table of situations where the lower rate may or may not be worth pledging property are covered too.
The rate in an ad is not your rate, and a longer term can add about $2,000 in interest on a $15,000 loan. Here is how to compare offers properly. A personal loan quote reflects your credit profile, your debt load, the term and the lender type, so the best rate comes from comparing several quotes on APR and total cost rather than on the monthly payment. This guide explains where bank, credit union and online lender rates come from, what moves the offer you receive, and how a $15,000 loan at the same 12% APR costs $2,935.56 in interest over 36 months but $5,020.20 over 60. It ends with a step-by-step checklist and the red flags, such as advance fees, that signal a scam rather than a lender.
A $15 fee on a two-week $100 payday loan works out to about 391% APR. No single US law defines predatory lending, but bank regulators describe the same core features: loans made without regard to whether the borrower can repay, repeated refinancing to collect new fees, and terms or add-ons hidden from the borrower. This guide turns those features into checks you can run on an offer. It works through the cost of rolling a $400 payday loan five times, a $1,000 loan that shows about 34% APR on the disclosure but about 46% under the Military Lending Act's formula, and the 2026 points-and-fees test for high-cost mortgages. It also covers state rate caps, credit union alternative loans, the three-day right to cancel some home-secured loans, and where to complain.
