Expense Ratio Checker
The whole cost base, read as a share: your real expenses against invoiced revenue, the gap against the assumption inside your rate, and what the gap is worth a year and an hour.
Open tool →Subscriptions are the expenses that never ask for a decision: each one arrived as a few dollars, none of them ever came back for approval, and the stack they form is a real cost of the practice that nobody has ever added up. This page adds it up. Enter every tool you pay for — what it bills, and whether it bills monthly or once a year — and annual lines are divided by twelve, because a yearly bill quoted whole is how a stack hides. On the seeded example below, eight ordinary lines total $110.98 a month: $1,331.76 a year, 1.59% of an $84,000 income, $27.75 a month carried by each of four active clients, and 1.17 hours of your time a month — 14.0 hours a year — at a $95 rate. This is the itemised version of the question the expense ratio checker answers as a share: that page reads all your costs against your revenue; this one reads the stack itself, line by line, and names its biggest line.
The eight lines are seeded with an example solo stack — a design tool at $15, accounting software at $23 and so on. They are examples to replace, not prices quoted for any product: rename every line, type what it really bills you, and set how it bills. Lines you do not use, set to zero.
Enter the subscriptions you actually pay for and this page totals them honestly.

Enter your stack and this line starts the audit for you, with the biggest line.
The lines pre-filled above are a complete worked example: an ordinary solo stack of eight subscriptions, one of them billed yearly. Enter those numbers and the auditor returns exactly this:
| Design tool, billed monthly | $15.00 a month |
| Project tool, billed monthly | $10.00 a month |
| Accounting software, billed monthly | $23.00 a month |
| AI assistant, billed monthly | $20.00 a month |
| Cloud storage, billed monthly | $9.99 a month |
| Scheduling tool, billed monthly | $12.00 a month |
| Website and hosting, billed yearly | $14.00 a month (entered as $168.00 a year, divided by 12) |
| One more app, billed monthly | $6.99 a month |
| Stack per month, normalised | $110.98 |
| Stack per year | $1,331.76 |
| Share of $84,000 of income | 1.59% |
| Per active client (4 clients) | $27.75 a month |
| In your time at $95 an hour | 1.17 hours a month · 14.0 hours a year |
| Biggest line | Accounting software, $23.00 a month (20.7% of the stack) |
Read the hosting line twice, because it is the page in miniature: entered whole, $168 looks like the second-biggest cost in the stack; divided by twelve, it is $14.00 a month — smaller than the accounting software. Annual bills flatter and frighten in the wrong places, which is why this auditor refuses to total them un-divided. And read the verdict honestly, too: at 1.59% of income, a stack this size is rarely the problem. The audit is not a hunt for a villain. It is the quarterly habit of making every line say what it is for — because the stack that is never read is the one that quietly doubles.
Read it beside its neighbours. The expense ratio checker takes the total this page builds — plus every other cost the business carries — and reads it as a share of invoiced revenue against the assumption inside your rate: this page itemises, that page judges the whole. The runway calculator is where the stack goes to be survived: subscriptions are fixed costs, they do not shrink in a quiet month, and the monthly total here is a load-bearing part of the burn that page divides your cash by.

Open tool →Subscriptions do not shrink in a quiet month. This divides the cash you could actually spend by the true monthly burn — the stack included — and dates the month the money runs out.
Open tool →The rate this stack is priced into: built from your target income, your real costs — subscriptions itemised here included — your tax estimate and the billable share of your week.
