Delinquency Carry Cost Calculator

Unpaid rent accrues carry cost every month through resolution.

Unpaid balance

Months delinquent

Cost of capital %

Collections + legal cost

Total carry cost

$2,295

Opportunity cost

$95

Total exposure

$6,095

How the math works

Opportunity cost = balance × (rate/12) × months. Total carry = opportunity + legal.

$3,800 × (10%/12) × 3 = $95 opportunity + $2,200 legal = $2,295 carry. $6,095 total exposure.

How this calculator works

What this page estimates

This Delinquency Carry Cost Calculator is built to give a quick, browser-based estimate for delinquency carry cost. Unpaid rent accrues carry cost every month through resolution. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the delinquency carry cost result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this delinquency carry cost estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

Why does delinquency have a carry cost?

Unpaid rent is effectively a zero-interest loan to the tenant. Your cost of capital (the return you could earn elsewhere — typically 7-12%) applies to that balance every month it sits unpaid. Plus you incur direct collections cost: posted notices ($25-75 per), attorney fees ($500-3,500 per case), filing fees ($100-450), process-service ($75-200). Institutional operators track 'carry cost per delinquent dollar' as a KPI alongside aging buckets.

When does carry cost exceed recovery?

When the math breaks, abandon and write off. Example: $3,200 unpaid balance × 18% annual carry + $2,500 legal + likely 40% collection rate = $1,880 all-in cost for $1,280 expected recovery = net $600 loss. Operators run this math at 60 and 90 days delinquent and often write off balances below $2,000-3,000 rather than paying legal fees. Smaller balances: ACH rejection → notice → cure or abandon.

What reduces carry cost?

Faster resolution: automated cure timelines (day 3 late notice, day 10 pay-or-quit, day 30 file), payment plans that cure rather than hold (ongoing rent + arrears in 6-12 months), quick-to-move-out incentives ($500-1500 cash for keys instead of eviction), and prompt write-off decisions on uncollectible. Speed is the enemy of carry — each month doubles direct + opportunity cost.

How do institutional operators handle this?

Monthly aging reports, automated escalation on day 3/10/30/60, in-house collections team or third-party (Hunter Warfield, RentPayment Collections), eviction filings on day 30+ in permissive states, alternative dispute resolution in tenant-friendly states, digital payment + portal to prevent disputes over receipt. Benchmark portfolio delinquency against NMHC survey data — median stabilized portfolio runs 1.5-3% of billed rent.
