Are you getting the full value from the customers you already have?
Most founders focus on winning new clients. The biggest untapped growth lever is usually sitting in the relationships they already have. This calculator shows you what your existing clients are really worth — and what you could be leaving behind.
Growth & Retention
Part of the CorpDoc Framework
This tool sits within the Growth & Retention pillar — it measures whether your existing customer base is compounding or quietly eroding in value. It connects directly to churn, expansion revenue, and the decisions that determine whether growth is sustainable or dependent on constant new acquisition.

Your Recurring Revenue Retention
Enter numbers for one complete period — one month or one quarter.
Carried over from your client retention results. We have pre-filled your starting recurring revenue using the monthly value of your returning clients from Path B. You can adjust any figure below — these are starting estimates, not fixed numbers.
What this is: The total recurring revenue — subscriptions, retainers, licences — that was active at the start of this period. Not invoices raised during the period, but what was already contracted and running on day one.
Where to find it: Your billing or subscription platform should show active MRR at a given date. If you use accounting software, look for a recurring revenue report or ask your bookkeeper to run a contracted revenue schedule.
If you cannot find it: Your books may not track recurring revenue separately from one-off income. That is a data capture gap — without it, your NRR calculation will not be accurate. Book a free Clarity Call →
Upsells, upgrades, or add-ons from customers already with you.
Not sure what counts? →
What this is: Any increase in recurring revenue from a customer who was already paying you — an upgrade to a higher plan, an add-on service, or an expanded contract. It does not include revenue from new customers.
Where to find it: Your billing platform should show plan upgrades and add-ons during the period. If you track revenue manually, look for customers whose monthly value increased during this period.
If you cannot separate this from new customer revenue: Most businesses that have not deliberately set up their billing or accounts to track expansion separately cannot find this figure. That is a data capture gap. Enter zero if you are not sure — your NRR result will be conservative. Book a free Clarity Call →
Customers who cancelled their subscription entirely.
Not sure how to find this? →
What this is: The total recurring revenue lost because customers cancelled entirely during this period — not downgrades, but full cancellations. Enter the value of what they were paying, not the number of customers.
Where to find it: Your billing platform's churn report, or a list of subscriptions that ended during the period with their monthly value. If you manage this manually, look for customers who were active at the start but are no longer paying.
If you do not track cancellations by revenue value: Many businesses know how many customers churned but not what those customers were worth. That gap means your NRR calculation will be an estimate. Book a free Clarity Call →
Customers who stayed but reduced their plan or spend.
Not sure what this means? →
What this is: The reduction in recurring revenue from customers who stayed but moved to a lower plan or reduced their spend. Enter the amount of revenue lost — not the number of customers, but the value difference between what they paid before and after.
Where to find it: Your billing platform should show plan downgrades during the period. If tracked manually, look for customers whose monthly value decreased without cancelling entirely.
If you do not track downgrades separately from cancellations: This is the hardest NRR component to find without a properly structured billing system. Enter zero if you are not sure — but be aware your NRR will be slightly optimistic. Book a free Clarity Call →

Compounding
Most of your clients are returning. Your relationships are already a growth engine — the opportunity now is to make this intentional so it accelerates further.
50% – 69%
Building
Around half your clients come back. You have natural loyalty — small, deliberate actions to stay in touch and offer ongoing value could shift this significantly.
30% – 49%
Early Signs
Some clients return, but most do not. The revenue you are leaving behind from those who didn't come back is likely larger than what you spend winning new ones. Fix this before spending more on marketing.

Untapped
Almost all your client value leaves after the first engagement. This is your highest-leverage opportunity — the people most likely to buy from you again already know and trust you.
