Calculators

Arithmetic You Can Check

Short answer

Four calculators using our actual posted rates. Every formula is printed under the result so you can verify it by hand.

Four tools built on OCRV Center posted rates: a repair cost estimator, a fleet downtime cost model, a claim out of pocket calculator and a paint hour converter. No email required and no results are stored.

Most repair calculators on the internet are lead capture forms with a random number generator attached. These are not. They use the same rates we post on the rate card, they show the formula, and nothing you type leaves your browser.

They will not replace an estimate, because an estimate requires somebody to look at the vehicle. What they will do is tell you whether a number somebody gave you is in the right neighborhood, which is genuinely useful information to have before a conversation.

Repair Cost Estimator

Calculator 01

Repair Cost Estimator

Builds a ticket the same way our estimate does. Labor is untaxed. Parts and materials are taxed at 7.75 percent.

Body hours

$210 per hour

Paint hours

$210 per hour plus $55 materials

Mechanical hours

$260 per hour

Parts cost before markup

Our cost, not retail

Job involves chemicals, refrigerant or LP (adds $45 hazmat)

Labor: $7,350
Parts with markup: $3,375
Materials: $925
Sales tax on parts and materials: $333
Estimated total: $11,983

Formula: (hours x rate) + parts markup + (paint hrs x $55 + body hrs x $5) + 7.75% tax on parts and materials

This is arithmetic, not an estimate. Real hours come from a teardown.

Fleet Downtime Cost

Calculator 02

Fleet Downtime Cost

For fleet operators the repair price is rarely the biggest number. This one usually is.

Revenue per unit per day

Contribution margin percent

Revenue minus variable cost

Units off the road

Spare units you can substitute

Expected days out of service

Units genuinely idle: 1
Gross revenue lost per day: $950
Margin lost per day: $333
Gross revenue lost total: $13,300
Margin lost total: $4,655

Formula: (units - spares) x revenue x margin% x days

Run this before you choose a shop on price. Two weeks saved on cycle time is frequently worth more than the entire difference in the estimate.

Claim Out of Pocket

Calculator 03

Out of Pocket on a Claim

What you actually pay once the deductible, any betterment and any uncovered work come off the top.

Total repair cost

Your deductible

Betterment charged

Often disputable. Ask why it applies.

Work the carrier will not cover

Prior damage, wear, uninsured upgrades

Carrier pays: $17,000
You pay: $1,000
Your share of the repair: 5.6%

Formula: carrier = repair - uncovered - deductible - betterment

If betterment or an uncovered line looks wrong, it is worth asking the adjuster to justify it in writing before you accept it.

Paint Hours and Materials

Calculator 04

Paint Hours and Materials

Converts surface area and condition into paint hours, which is what drives both the labor and the materials charge.

Area to refinish, square feet

A 40 ft coach side is roughly 320 sq ft

Substrate condition

Paint system

Estimated paint hours: 54.0
Paint labor at $210: $11,340
Paint materials at $55 per hour: $2,970
Paint portion with tax on materials: $14,540

Formula: (sq ft / 8) x condition factor x stage factor, then x $210 labor and x $55 materials

Body hours, masking of adjacent panels and blend into neighboring panels are separate. This is the paint portion only.
