8M+/month - Debt PayoffHot
Debt Payoff Calculator
Enter all your debts and an extra monthly payment. The calculator simulates month-by-month payoff using snowball (smallest balance first) or avalanche (highest APR first) and compares against the minimum-only baseline.
1.5M+/month - True AffordabilityNew
House Affordability Calculator (Beyond DTI)
Drop your gross income, existing debts, down payment, property tax + insurance rates, mortgage rate, term, HOA, maintenance reserve, and job-stability score. Calculator returns three max-purchase tiers — Conservative (33 % back-end DTI + 1 % maintenance), Standard (36 % + 0.5 %), Aggressive (43 % + 0 %, the FHA ceiling) — plus the stretch spread that shows how much more ‘affordable’ a DTI-only calc claims by ignoring maintenance reserve. The differentiator vs every other affordability tool: maintenance and risk are baked into the housing cost, which is the entire reason DTI-only calcs lure buyers into stretch purchases that break their budget by year three.
1.2M+/month - CC PayoffHot

Drop your balance and APR, then either set a monthly payment to see how long it takes (and what interest you'll pay), or pick a target timeline and the calculator solves for the required monthly payment. Flags the case where your payment can't cover monthly interest.

Buy vs Rent True Cost Calculator
Drop home price, down %, mortgage rate, term, property tax, HOA, maintenance, insurance, expected appreciation, current rent, rent inflation, alt investment return, time horizon, transaction cost %, and marginal tax rate. Calculator runs an NYT-style net-worth-at-horizon comparison: both paths start with the same down-payment cash; renter invests it in the market; whichever path has lower annual housing cost invests the cash-flow surplus at the alt-return rate. Output: net-wealth delta at horizon, break-even year, and sensitivity to ±1 pp shifts in appreciation and rent inflation.
550K+/month - PSLF / SAVENew

Frequently Asked Questions
The most common questions we get about this calculator — each answer is kept under 60 words so you can scan.
Are these finance calculators accurate enough to make a real decision?
Yes for the math — the EMI, mortgage, compound-interest, and affordability formulas are the same ones banks and lenders use, hand-verified against published sources. They are not a substitute for professional advice on tax, regulation, or fee structures specific to your lender.Why does the AI insight matter for finance calculators?
Because a number alone rarely answers the real question. A $1,840/month EMI is fine — until you see it eats 41% of your take-home. The AI insight turns the raw output into context: how it compares, where the risk is, and one specific lever (extra payment, shorter term, lower rate) you can pull.Do you store any of the financial information I enter?
No. Inputs are processed in your browser — only the inputs and result are sent to our AI proxy to generate the insight, and nothing is logged or persisted. Closing the tab erases the calculation. There is no account, no history, no tracking pixel inside the calculator.Which calculator should I start with?
Start with whichever decision is in front of you. Buying a home → Mortgage. Taking a loan → Loan/EMI with extra-payment analysis. Saving for the long term → Compound Interest. Wondering if a purchase is realistic → Can I Afford This?. Most users run two or three before signing anything — that is the right instinct.
