Questions

Everything you wanted to ask

Quick answers about the tools in this category — what they cost, what they need and how they work.

Still have a question? We usually reply within one working day.

Which money questions can these calculators answer?
Common ones. There is an AI Loan Calculator and an AI EMI Calculator for repayments, an AI Mortgage Calculator for home costs, an AI Compound Interest Calculator for savings, and an AI Debt Snowball Planner for clearing balances in a sensible order.

Can I check a margin before I set a price?
Yes. The AI Profit Margin Calculator works out what you keep after costs, and the AI Break Even Calculator says how many sales cover your outlay. The AI ROI Calculator is the one to open when you are judging a spend after the fact.

Do the calculators show their working?
They explain the answer in plain wording rather than dropping a bare number on the screen. That makes it easier to sanity check your inputs, and easier to repeat the same sum next month without wondering which figure went where.

Is there a quick way to work out a discount?
Open the AI Discount Calculator, enter the original price and the percentage off, and it returns the sale price plus the amount saved. The AI Percentage Calculator handles the wider set of percentage questions that come up in the same breath.

Do I need an account to run one?
No account or sign up is needed. Each calculator runs as a guest tool in the browser and is free with no cost and no trial. Signing in is optional and only saves your history so an old result is easy to find.

Can I keep a copy of the result?
Results export in TXT, DOC and HTML with one click, which helps when a tax figure or a repayment schedule has to go into an email or a document. Copy and paste is fine when you only need a single number.

Will these work on a phone in a shop?
Everything works on phones, tablets and desktops with nothing to install, so a quick tax or discount check at the counter takes seconds. The tools are AI powered and return results in seconds even on a modest connection.
