Ten starter calculators, one pricing engine

“No-code calculator builder” is already a crowded category. So tinymath doesn’t lead with that pitch — it leads with the calculator a business already needs: an Instant Printing Quote Calculator, a Solar Installer estimate, a HVAC sizing bracket.

Under the hood, all ten starter calculators in the library run on the same engine: inputs, operators, and conditions assembled from blocks, with if <condition> then <value> else <value> as a real value-producing branch — not just a check. That one piece of logic turns out to cover most of the real pricing rules these trades already use:

• A tiered volume discount (printing) — the per-unit rate drops once an order crosses a quantity threshold.
• A sizing bracket (HVAC/solar) — the rate depends on which range a job’s size falls into.
• A plain eligibility check (government/NGO aid) — no price at all, just a yes/no.

Every industry calculator on /calculators is a barebone starting point, not a finished product for that trade — the vertical name is the product; the block engine underneath it is the implementation detail most people won’t ever need to see.
