Operating Leverage Contribution Bridge

Review how a sales change flows to operating income through contribution. Preparation only, not an account action.

What to provide

Sales, variable costs, fixed costs and the proposed sales change.

How it works

1. Compute contribution and the contribution ratio.
2. Apply the sales change to contribution, holding fixed costs constant.
3. Show the operating income change in money and percent.
4. Return the bridge without a forecast claim.

The output

sales | contribution | fixed_costs | change_pct | income_change | income_change_pct | forecast_unproved

Worked fictional example

Fictional sales 1000, variable 400, fixed 500: contribution 600, income 100. A 10% sales rise adds 60 contribution, lifting income to 160, a 60% rise. The sixfold flow-through is arithmetic on these numbers, not a promise.

Checks and limits

Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
