Will I Recover This Invoice? Recovery Probability Calculator
Wondering whether an overdue B2B invoice is worth chasing? This recovery probability calculator estimates the odds of getting paid based on the four factors that matter most: how long the invoice is overdue, whether the debtor has responded, how many contact attempts have already failed, and the invoice amount. Enter your details below for an instant, indicative recovery probability. The biggest driver is age: every week past 90 days quietly lowers your odds, which is why the answer to "should I act now?" is almost always yes.

A low score is not a write-off. Older and silent accounts are exactly where intelligence-led collection makes the biggest difference, because the limiting factor is usually reachability and persistence, not the debtor's ability to pay. AgentCollect assigns one AI agent per account, enriches stale contacts (+130% contacts found), and works the account across email, phone, SMS, and attorney letters over a 12-month mandate. Trusted by Fortune 500 companies including Microsoft and Dell. Founded 2020, YC S23.
Indicative estimate only. This calculator applies a transparent heuristic based on well-established collection dynamics (older debt and silent debtors recover at lower rates; responsive debtors and fresher invoices recover at higher rates). It is not a guarantee, a prediction of any specific outcome, or financial advice. It does not use your real account data and cannot see the debtor's actual financial condition. Actual recovery depends on documentation quality, debtor solvency, contact accuracy, and the collection method used. For a projection based on your real portfolio, book a call.
How It Works
What Drives the Probability of Recovering an Invoice
Recovery probability is not random. Decades of collection data point to a handful of factors that move the odds far more than the rest. Age is the dominant driver. A fresh invoice (under 30 days past due) recovers at a high rate because the contact is still valid, the debt is still top of mind, and the debtor's cash position has not yet deteriorated. As an invoice ages past 90 days, recovery probability falls by roughly one percentage point per week. By 180 days, the contact has often gone stale, the original decision-maker may have moved on, and the debt has lost priority inside the debtor's organization.
Responsiveness is the second-strongest signal. A debtor who replies, even to dispute the charge or ask for more time, is engaged and reachable, which is most of the battle. A silent debtor is far harder because you cannot tell whether the contact is wrong, the invoice was never seen, or the debtor is deliberately stonewalling. A responsive debtor can roughly double the recovery probability of an otherwise identical account.
Failed contact attempts work against you. Each round of outreach that produces no resolution is weak evidence that the standard playbook is not landing, usually because the contact data is wrong or the debtor is deprioritizing the debt. Amount matters too, but in a U-shape: very small invoices are often abandoned because manual chasing costs more than the debt, while very large invoices can be harder to extract in a single payment and may require structured plans.

The key insight: past 90 days, the limiting factor shifts from "will they pay?" to "can I still reach the right person?" That is precisely the gap intelligence-led collection closes. When people actually pay debt and AR recovery strategies go deeper on the timing.
FAQ
Frequently Asked Questions
How do you calculate the probability of recovering an invoice?
Recovery probability is driven mostly by four factors: how long the invoice is overdue, whether the debtor has responded at all, how many contact attempts have already failed, and the invoice amount. The single biggest driver is age. Fresh debt (under 30 days past due) recovers at a high rate, while debt past 180 days drops sharply because contact information goes stale, decision-makers move on, and the debtor's own cash position deteriorates. A responsive debtor roughly doubles the odds versus a silent one. This calculator combines those factors into a single indicative percentage.
Why does recovery probability drop the longer an invoice is overdue?
Three things happen as an overdue invoice ages. First, contact data goes stale: the AP contact leaves, the phone number changes, the email bounces. Second, the debt loses priority inside the debtor's organization; newer obligations get paid first. Third, if the debtor is in financial distress, every week reduces the pool of cash available. As a rule of thumb, recovery probability falls by roughly one percentage point per week beyond 90 days past due. This is why starting collection early matters more than any other single decision.
Does a debtor responding to my emails mean I will get paid?
Not guaranteed, but it is the strongest positive signal you have. A debtor who replies, even to dispute the charge or ask for time, is engaged and reachable, which is most of the battle. Silent debtors are far harder because you cannot tell whether the contact is wrong, the invoice was never seen, or the debtor is deliberately ignoring you. A responsive debtor can roughly double the recovery probability of an otherwise identical account. The next step with a responsive debtor is usually a structured payment plan rather than escalation.
How does AI collection improve recovery probability?
AI collection improves the odds in three ways. It fixes the stale-contact problem with Contact Finder, which enriches a debtor profile from a single email address (+130% contacts found), so silent accounts often become reachable. It assigns one AI agent per account rather than one human stretched across 250+ accounts, so no account is abandoned after two emails. And it calibrates tone dynamically: push too hard and debtors fight back, push too soft and they ghost you. AgentCollect recovers approximately 50% of accounts within 20 days versus 20-30% over months for traditional agencies.
Is a low recovery probability a reason to give up on an invoice?
No. A low score means the manual, low-effort approach is unlikely to work, not that the money is gone. Older and silent accounts are exactly where intelligence-led collection makes the biggest difference, because the limiting factor is usually reachability and persistence, not the debtor's ability to pay. With a 12-month mandate, multi-channel outreach (email, phone, SMS, attorney letters), and same-day direct payment, accounts that look dead to a manual process are routinely recovered. The score tells you which accounts need a real agent, not which to write off.
