Suggest a Tool

Help shape what BoringToolsKit builds next. Suggest a calculator or everyday tool, see where new tools are already planned, and copy or email a ready-made suggestion — all from this page, with nothing transmitted to our servers.

Tell us what to build next

We add tools that solve a real, repeated calculation. A good suggestion names the problem you keep solving by hand and who it is for. This form runs entirely in your browser — it does not submit or store your message. Copy the note, open an email draft, or share it.

What we look for in a suggestion

  1. Specific and testable. We can build and verify a clear formula or output.
  2. Repeated need. Tools people reach for more than once.
  3. Private by default. It should be usable without an account or uploading inputs.

Where new tools are already planned

Our public roadmap lists the priorities we are working toward. Sending a suggestion is the fastest way to help us decide what to build first.

How a suggestion actually moves through the pipeline

A worked example of what we see on our side: suppose a suggestion arrives for a break-even calculator. We first check demand against the catalogue. If 'break-even point' gets roughly 40,000 US searches a month and we have zero coverage, it starts near the top of the queue. If the same term returns 12 existing tools competing on it, priority drops regardless of demand, because page 1 is already saturated.

Next we check whether the math is even well-defined. Break-even is: fixed costs divided by (price per unit minus variable cost per unit). With $8,000 in fixed monthly costs, a $25 product and $15 in variable costs per unit, that is 8000 / (25 - 15) = 8000 / 10 = 800 units per month to break even. That passes our test: one formula, checkable inputs, a number a spreadsheet already confirms. Suggestions that pass this shape typically go from queue to live build in 2 to 6 weeks; ones needing scraped private data or accounts sit in 'deferred' indefinitely, and we say so on the roadmap.

Where suggestion-based tools still fall short

Even a shipped tool has edges that no suggestion fixes, so it is worth knowing them before you ask. Marketplace fee calculators are the clearest case: a $30 item on a marketplace charging 15% referral plus $0.30 per order keeps 30 - 4.50 - 0.30 = $25.20 before shipping. But if the fee schedule changes mid-month, our published table is stale until the next review cycle, which historically runs about 30 to 45 days. We mark the review date on every page rather than pretending rates are live.

Two other recurring limits: currency and locale. A payroll or sales-tax tool tuned for US rules gives wrong answers for, say, VAT at 20%, which is why region-specific requests are labelled by jurisdiction in the roadmap instead of folded into the generic version. And any tool that needs your actual numbers, like margin on real sales volume, only works as well as the inputs; the calculator guarantees the arithmetic, not the data. If you hit one of these edges, use the correction link at the bottom of the page and we will recheck the specific figure.
