Tools that show their math
Every tool on this site computes in your browser, shows its result instantly (never behind an email gate), and publishes its full model — formulas, assumptions, and sources — on the same page. If a tool’s answer would embarrass us, the tool still prints it: the pet breakeven calculator regularly tells people not to buy.
Am I overpaying for car insurance?
Ten questions, 60 seconds: an instant estimate range of what you may be overpaying, with the scoring model published on the page.
Life insurance needs calculator
The DIME method — debts, income, mortgage, education — minus the coverage and savings you already have.
Home insurance premium estimator
Your rebuild cost turned into a labelled premium range from a fully published model. No fake precision.
Renters insurance cost estimator
Belongings, liability, deductible, ZIP — an estimate anchored to the $171/yr national average (III/NAIC).
Pet insurance breakeven calculator
Premiums vs. your expected vet bills, shown line by line — and built to sometimes say ‘don’t buy’.
Travel insurance cost estimator
The published 4–6%-of-trip-cost band, adjusted for traveller age, with an optional CFAR rider.
How our tools are built
- Published models. The formula is on the page. If you cannot see how a number was produced, we have failed — tell us via the contact page.
- Ranges, not fake precision. Where reality is a range, the tool shows a range and explains its width.
- Your answers stay on your device in this release. See the privacy policy.
- Estimates are not quotes. Only an insurer can price your actual policy.
