Planning & Cash Calculators

A plan is a handful of numbers that depend on each other: what you must sell to cover costs, how long the cash in the bank lasts, how many proposals turn into the revenue you want, and what the tools you pay for every month add up to over a year. These calculators each take one of those questions and give you a figure you can act on, with the arithmetic shown so you can challenge the inputs.

They are deliberately simple. The point is not a forecast model but a quick, honest check before a decision: a price change, a hire, a subscription, a new revenue target.
