Cake pricing calculator
Cost a recipe by the pack sizes you buy, add your hours, overhead and target margin, and get a price for the cake and a price per serving. Eleven currencies, metric and imperial.
Calculators, no sign-up
Calculators for the sums that come up around our templates. They run entirely in your browser: the numbers you type stay on your computer, nothing is uploaded, and none of them ask for an email address. Each one pairs with a spreadsheet that keeps the working.
Nearly all of them work in any country, most carry a selector with eleven currencies, and none of those assumes a country’s tax rules, filing deadlines or units. Two are the exception. The Making Tax Digital checker and the 5% VAT renovation calculator are both about HMRC’s rules, and both say so at the top.
Renovation contingency calculator
How much contingency to add to a renovation quote, based on the type of work, the age of the property and the risks you already know about. Eleven currencies, and no country’s permit or tax rules inside it.
Airbnb break-even occupancy calculator
The occupancy a short-term let needs before it covers its costs, plus monthly and annual net profit, net margin and a comparison against letting long term. Eleven currencies, and break-even is a cash question everywhere.
Gumroad fee calculator
What you actually keep on Gumroad, Payhip, Ko-fi, Lemon Squeezy and Etsy, with the 2026 fee chains applied in the right order. Eleven currencies, an editable exchange rate for the fees priced in US dollars, and EU, UK and US sales-tax positions all covered.
Making Tax Digital spreadsheet checker
UK only. Whether MTD for Income Tax applies to you yet, when your quarterly updates fall due, and what HMRC expects a spreadsheet to record before you file through bridging software.
Executor checklist generator
Answer five questions and get a personalised, printable executor checklist with typical probate target dates against each task. It names no country’s deadlines, on purpose.
Residuary estate calculator
The whole waterfall: assets, less debts, funeral and administration costs, less the gifts and cash legacies, then the residue divided by share. When the legacies come to more than the estate can pay, it abates them in the usual order instead of showing a negative number.
Empty property cost calculator
What an empty house costs a month once the council tax premium, unoccupied insurance and standing charges are in one place, plus what it has run up so far. It uses your own bill and your own premium rather than a table of council rates.
Builder quote comparison calculator
Three quotes onto one basis: your allowance added back for whatever a quote leaves out, provisional sums swapped for what you expect to spend, the same tax footing on all three, then ranked on true cost. Eleven currencies, and no tax rate assumed.
Airbnb furnishing cost calculator
An itemised, printable shopping list for a short-term rental, with quantities from your bedrooms and bathrooms, three finish levels, editable prices and the number of booked nights it takes to earn the setup back.
Contractor payment schedule calculator
A contract value in, a dated draw schedule out: what each stage is worth, what tax goes on it, what retention comes off it, and the date the retention falls due. Four stage patterns to start from, all editable. Eleven currencies, and no country’s building or tax rules inside it.
5% VAT renovation calculator
UK only. Whether your job looks like one of the reduced-rate categories, what the gap between 20% and 5% is worth on your own spend, and the evidence list to hand the contractor. The rates are typed by you rather than hard-coded, because they move.
Executor interim distribution calculator
How much an executor can safely release now and how much has to stay behind, with a payment per beneficiary and the working shown. Eleven currencies, and it names no country’s claim periods: the buffer for the unknown is yours to set.
Inherited property sale calculator
Estate agent, auction or cash buyer, compared on the net to the estate rather than the headline price, with every route paying for the months it takes. Tells you what a cash offer would have to be to match the best of them. Eleven currencies, and the tax layer is optional and yours to set.
Do I need probate?
There is no national probate threshold: every institution sets its own release limit. Enter each account, how it is held and the limit that bank gave you, and get a verdict per account instead of one answer for the whole estate. Eleven currencies, and it states no jurisdiction’s rules.
Sibling buyout calculator
What one heir pays the others to keep an inherited house: net equity after the mortgage, each person’s share, and credit for whoever has been paying the mortgage or fixing the roof. Eleven currencies, no lead form, and no financing rates anywhere in it.
Inheritance equalisation calculator
How to split an estate when one child was given money years earlier. Brings the lifetime gifts back in, divides by share, deducts each advance, and handles the case where somebody already had more than their share. Framed as what a hotchpot clause produces, never as an entitlement.
Cake delivery fee calculator
What to charge to deliver and set up a cake: the round trip at your own fuel price, the driving and the setup at your hourly rate, a loading for tiered work that can go wrong, and your margin. Eleven currencies, metric or miles.
When a calculator is not enough
A calculator answers one question and forgets it when you close the tab. The spreadsheets keep your ingredients, your quotes, your bookings, your estate schedule and your ledger, so the second answer takes seconds instead of minutes.
