Loan Guides
Every guide here is built the same way: the actual math with worked numbers, the decision framework, and the pitfalls that cost real money — no filler. Comparison guides help you choose between strategies; calculator guides go deep on a single loan type and sit alongside the interactive tool, so you can read the theory and run your own numbers on the same page.
Comparison & decision guides
Biweekly vs Extra Monthly Payments: Which Pays Off Your Mortgage Faster?
Biweekly payments and adding 1/12 of your payment monthly are mathematically identical — 26 biweekly payments equal 13 monthly payments per year. The real differences are fees, automation, and flexibility. Worked numbers on a $300,000 mortgage show which approach fits which borrower.
PSLF vs Income-Driven Repayment: Which Path Out of Student Debt Saves More?
PSLF forgives the balance tax-free after 10 years of public-service employment; income-driven repayment alone forgives after 20–25 years, potentially with a tax bill. The worked numbers show when each path wins — and when aggressive payoff beats both.
Mortgage Recast vs Refinance: The Cheaper Way to Lower Your Payment
A recast applies a lump sum to principal and re-amortizes your existing loan for a $150–$500 flat fee — no closing costs, no rate change, no credit check. A refinance replaces the loan entirely. The worked numbers show which move fits which goal.
