About KindHow
How much to give, and why that much
KindHow started with a question the internet answers badly: how much to put in a wedding card. Search it and you get the same range on every page — fifty to two hundred dollars, use your judgment — with no indication of where those numbers came from or what would move you within them. That is not an answer. It is a shrug with a dollar sign in front of it.
So Eric built the thing the shrug was standing in for. KindHow is a collection of free, no-account-required tools that give you a specific amount for your specific situation — and then show you the arithmetic, line by line, so you can disagree with any part of it and watch what that does to the total.
Eric builds and runs the Veraino network of free calculator sites, where the house rule is that a tool has to show its work. KindHow applies that rule to the one category where nobody does it — questions whose answer is a social norm rather than a published fact. That category is not exempt from showing its work. It is the category that needs it most, because the alternative on offer everywhere else is a number with nothing behind it.

How it works
Every tool on KindHow is grounded in a documented method — but this site covers a category where the honest thing to say is that no single right number exists. What to tip a mover, what to give at a wedding: these are social norms, not published formulas, and any site implying otherwise is making something up. So rather than pretend, we publish the model itself.
That model is the Kindhow Scale. Every answer starts from a baseline drawn from a real publication — The Knot's wedding studies, the Emily Post Institute's holiday tipping guidance, industry and consumer surveys, published school-district gift limits, national tourism boards — and then applies the adjustments you select. Each line of the result shows what it added or removed, and carries one of two labels: sourced, meaning a publication backs it, or house judgment, meaning it is our model's reasoning and nothing more. We will never dress the second kind as the first. The full scale — every baseline, every factor, and the version it changed in — is published so you can check it or argue with it.
Our commitments
- Free, no sign-up required. Every tool on this site is free to use with no account, subscription, or paywall.
- We show our work. Every tool explains its methodology, cites its sources, and surfaces assumptions — so you can verify the logic, not just trust the output.
- Honest about limitations. Where precision is limited or assumptions are required, we say so. Tools compute; they don't replace professional judgment.
- Kept current. Tools that use figures that can change over time carry a “last reviewed” date and are treated as an ongoing maintenance responsibility, not a one-time build.
