Screening cost ROI.

Tenant screening cost calculator measures ROI on screening expenditure. 100 applicants screened at 30 each = 3,000 cost. 50% prevention rate × 5% bad tenant rate = 2.5 bad tenants avoided. Each bad tenant costs 15,000 (rent arrears, damage, eviction) = 37,500 saved. Net benefit 34,500 - 1,150% ROI on screening.

Example: process 100 applications/year, 30 screening cost each. Total screening: 3,000. Prevention rate 50% × bad tenant rate 5% = 2.5 bad tenants avoided. Each bad tenant cost (eviction 3-5k + 6 months rent loss 6-12k + damage 2-5k) ≈ 15,000. Total savings: 37,500. Net benefit: 34,500. ROI: 1,150%.

Tenant screening best practices: (1) Credit check (15-25 per applicant). (2) Income verification (3x rent rule). (3) Previous landlord references (free, 30 mins). (4) Employment verification. (5) Identity verification. (6) Right-to-rent check legal requirement). (7) Eviction history search. (8) Criminal background check (legal limits vary). Total cost 30-50 per thorough screen. Avoiding one bad tenant pays for screening 1,000 applicants. Most cost-effective property management activity.

Quick example

With applications processed annually of 100 and screening cost per application of 30 (plus bad tenant cost of 15,000 and screening prevention rate of 50%), the result is 34,500.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Applications Processed Annually, Screening Cost per Application, Bad Tenant Cost (eviction + damages), and Screening Prevention Rate %. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

What's happening under the hood

Bad tenants avoided = applications × prevention rate × baseline bad rate (5%). Net = savings - costs. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Using this well

Treat the output as one point on a wider map. Run it three times — a pessimistic case, a central case, and a stretch case — and plan against the pessimistic one. That habit alone separates people who stick with an investment plan from those who bail at the first wobble.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.
