Loan payoff + decision guides
Plain-language explainers on the parts of consumer- and business-loan math that are easy to get wrong. Pick the lane that matches the decision you're actually making — refinancing is about whether a new loan beats the old one; prepayment is about where the next extra dollar should land.
Refinance
Refinancing is the replacement decision: is a new loan better than the old one once rate, term, fees, and how long you'll actually keep it are all on the table? The bridge guide compares it against the prepayment alternative; the dedicated calculators are the refinance calculator for the full scenario and the break-even calculator for the months-to-recover-costs question.
Refinance vs prepay — new loan or extra payments? →
Should you refinance to a lower rate or just throw extra at principal? The honest math on closing costs and break-even.
Refinance a personal loan or pay it down? →
When refinancing a personal loan beats just throwing extra at principal, and when it doesn't.
Refinance vs sell-and-buy — which move wins? →
When to refinance your existing mortgage vs. sell and buy a different home, including the rate-lock-in cost most calculators ignore.
Prepayment
Prepayment is the capital-allocation decision: should the next extra dollar of cash go into this loan, when should it land to do the most work, and what cadence will you actually stick to? Pair these with the biweekly payment calculator or your loan-type payoff calculator for the numbers on your specific balance.
How extra payments move the payoff date →
The real math behind extra payments — why $100/month in year 1 saves 4x more than $100/month in year 4, with a worked example you can verify on the calculator.
One big payment or smaller extra payments? →
If you have a windfall, when does dropping it on the loan beat spreading it as monthly extras?
The fastest payoff methods, ranked →
Refi+shorten, $200 extras, $5k lump, $100 extras, biweekly — ranked by months saved on a $25k baseline. With the decision rule for which to pick.
Principal-only payments — make extras count →
Why paid-ahead routing can blunt the savings your payoff calculator shows, and the lender-by-lender operational fix. Worked example with real numbers.
Check the fee before you prepay →
Which loan types still charge for paying off early in 2026 — auto, mortgage, personal, SBA, business — and how to spot them.
SBA prepayment penalties — 7(a) and 504 →
When the SBA prepayment penalty applies, how it's calculated, and how to time prepayments to minimize it.
How much does one extra payment save? →
Worked examples on personal loans, mortgages, and auto loans + the timing rule that matters more than the amount.
Auto loan extras — months and dollars saved →
Concrete months-saved + interest-saved numbers at $50, $100, $150, $200 extra monthly on a typical $30k auto loan, plus the lender-routing trap that quietly halves most savings.
Should you pay off your auto loan early? →
GAP-insurance refund mechanics, title-release timing, prepayment-penalty traps, opportunity-cost math. When early auto-loan payoff actually saves money.
Auto loan early payoff — what to check first →
The operational checklist before you send a lump sum or set up extra monthly payments — prepayment penalties, title timing, GAP refunds, lender-routing for principal-only, liquidity check.
Debt consolidation and payoff strategy
For when you have several balances and the question is how to order them — or whether to wrap them into a single loan. Avalanche versus snowball, the behavioral break in most consolidations, and the operational decisions after the new loan funds.
Should you consolidate debt with a personal loan? →
When rolling credit-card debt into a personal loan actually saves money, and the behavioral trap that quietly breaks most consolidations.
What happens after you consolidate debt →
Why a successful consolidation can still leave you worse off, and the structural fixes that decide whether the loan actually pays off.
Pay off the small loan first or the high-rate one? →
Plain-language avalanche-vs-snowball framing with concrete numbers — when the math wins, when behavior wins, and when neither rule applies.
Government-backed mortgages
VA, FHA, and USDA loans have separate eligibility rules, fee stacks, and exit playbooks. These cover how each program works, what it costs you over the life of the loan, and the refinance move that drops the program's lifetime fees once you no longer need them.
VA loan guide — eligibility, funding fee, IRRRL →
How VA home loans work, who qualifies, and the no-PMI advantage that affects payoff strategy.
FHA loan guide — MIP and the refinance exit →
How FHA loans work, when to choose them, and the refinance-out playbook for dropping lifetime MIP.
USDA loan guide — rural areas, fees, eligibility →
How USDA Rural Development loans work, including the eligibility map and the two fees that affect total cost.
Business credit and overdrafts
For when you're reading a commercial term sheet. A seven-piece cluster: how facilities are priced, what the bank actually earns on the relationship, how overdraft interest works on the borrower side, the field guide to facility types, and a pre-call memo for negotiation.
Types of business credit facilities — a field guide for borrowers →
Overdraft, revolver, ABL, LC subfacility, equipment line, term loan — what each facility is, when banks offer it, and how each one charges you.
Base rate vs cost of funds pricing — how your facility rate is built →
Prime, SOFR, BLR, internal FTP — what each pricing basis actually means and why the same 'spread' can produce different all-in rates on two facilities.
Spread vs yield on a business facility — what each one measures →
Spread is a fixed property of the facility. Yield depends on how much gets drawn. Why they aren't the same number, with a $1M worked example.
How business overdraft interest is calculated — and what fees actually add up →
Daily-accrual formula, day-count basis, commitment fee, arrangement fee, and effective APR — explained with a $250K worked example.
Net interest income on a credit line — how lenders model facility earnings →
On a $1M line, NII can swing 16× from idle to fully drawn. Why utilization, not the rate, is the dominant lever.
How banks make money on business credit facilities — a borrower's x-ray →
Spread is the visible piece. Commitment fees, deposit balances, treasury cross-sell, and capital cost shape what the bank actually earns on the relationship.
How to negotiate a business line of credit — a pre-call memo for borrowers →
What is actually negotiable beyond the rate: spread, commitment fee, facility size, fee basis, covenants, reporting burden. A practical pre-call memo.

Read these before you sign a new loan. How to evaluate an offer past the headline rate, and how typical auto-loan terms shape what you'll actually pay across realistic balances and APRs.

The four numbers that actually matter on a loan offer, plus the contract red flags most borrowers miss. No lender recommendations.
How long to pay off a $20k or $30k auto loan? →
Monthly payment + total interest at $20k and $30k across every common auto-loan term and APR, plus the term-length trade-off most articles skip.
