Positive margin
A positive margin is uncommitted room inside the entered proposal budget, not a recommendation to add more features. Preserve it for omissions, cancellation exposure, or the choice to spend less.
Practical relationship planning
Proposal Comparison Calculator
Compare two marriage-proposal event plans after adding separate cash contingencies and valuing the coordination hours each plan requires.
TWO PROPOSAL PLANS, ONE BUDGET
Compare the full planning burden before choosing a proposal format
This calculator is for someone choosing between two concrete marriage-proposal event plans. It turns each plan’s listed cash cost, contingency allowance, and coordination time into a protected planning cost, then shows the remaining budget margin. The hour value is a private tradeoff parameter, not a price on the relationship or a forecast of whether a proposal will be welcomed.

TWO PROPOSAL PLANS, ONE BUDGET
Proposal plan protection ledger
Compare like with like: both base-cost totals must include the same categories, and a negative margin means the plan exceeds the entered budget before any unlisted items.
| Plan layer | Base / hours | Rate or reserve | Protected effect |

CURRENT CALCULATION PROCESS
Formula, default substitution, intermediate steps, and reconciliation
P_i = C_i(1+r_i) + h_i v; M_i = B - P_i
For each option, multiply listed cash cost by one plus its contingency rate, add coordination hours multiplied by the user’s hour value, and subtract that protected total from the common budget.
| Symbol | Meaning | Unit | Default |
|---|---|---|---|
| Pᵢ | Protected planning cost for option i | $ | calculated |
| Cᵢ | Listed cash cost for option i | $ | A 1,800; B 1,500 |
| rᵢ | Cash contingency rate | dimensionless | A 10%; B 15% |
| hᵢ | Coordination time | hours | A 12; B 20 |
| v | User-selected planning-hour value | $/hour | 25 |
| B | Protected proposal budget | $ | 2,500 |
| Mᵢ | Budget margin for option i | $ | calculated |
Conversions and rounding: Convert each contingency percentage once by dividing by 100. Hours multiplied by dollars per hour produce dollars. Keep full precision until display rounding to cents.
RESULT INTERPRETATION
Read protected cost and budget margin as separate signals
The lower protected-cost plan uses less of the declared budget after its own reserve and coordination burden are included. That ranking is useful only when both plans use the same cost boundary and the entered hour value reflects the decision maker’s real tradeoff.
Negative margin
A negative margin quantifies how far that plan exceeds the protected budget before unlisted items. It is a signal to change scope, timing, or budget—not to remove a contingency silently.
Equal protected costs
A tie means the arithmetic cannot distinguish the plans at the current assumptions. Compare privacy, accessibility, consent, cancellation terms, and operational complexity directly rather than forcing a numeric winner.
DECISION BOUNDARIES
Choose a proposal format only after checking the comparison boundary
Use the result as a logistics screen. The supported decision is whether either defined plan fits the protected budget and workload—not whether, when, or how another person should be asked to marry.
Category parity
Confirm that travel, ring, photography, meals, guests, gratuities, and cancellation costs are either included in both options or excluded from both.
Operational feasibility
Review the coordination hours against actual time available before the intended date. A plan can fit the cash budget while exceeding the available planning capacity.
Non-financial vetoes
Privacy, consent, safety, accessibility, and the other person’s preferences override a favorable cost ranking and must be evaluated outside this model.
SENSITIVITY AND STRESS TESTING
Stress-test the assumptions that can reverse the preferred plan
The preferred option can change when contingency or planning-hour value changes. Recalculate deliberately instead of treating the default assumptions as facts.
Hour-value crossover
Test zero, the value of displaced paid work, and a higher scarcity value. If the preferred plan changes, coordination burden—not cash price—is controlling the comparison.
Vendor uncertainty
Increase only the contingency for the plan with weaker quotes, deposits, or cancellation terms. Applying the same reserve to unequal uncertainty can hide the riskier option.
Budget compression
Reduce the protected budget to the amount that remains after emergency and near-term obligations. A plan that becomes negative under that boundary is not robustly affordable.
HOW TO USE
Build two comparable proposal plans
- Define the same cost boundary for both options before entering prices.
- Estimate coordination hours from an actual task list rather than enthusiasm or anxiety.
- Choose a contingency that reflects each plan’s booking uncertainty.
- Set the protected budget independently of which option you prefer emotionally.
- Review both the protected cost and margin, then discuss consent, privacy, accessibility, and safety outside the arithmetic.
SUBJECT FUNDAMENTALS
What the comparison includes and excludes
- Listed cash cost
- The priced items deliberately included in each proposal plan.
- Contingency reserve
- A cash allowance for uncertain prices or small omissions, not automatic permission to spend it.
- Coordination time
- Hands-on work needed to research, arrange, confirm, and execute the plan.
- Opportunity-cost proxy
- A user-defined conversion of planning hours into comparable dollars.
- Budget margin
- The entered budget minus protected planning cost; negative means over budget.
MODEL AND FORMULA
Protected cost, not emotional value
P_i = C_i(1+r_i) + h_i v; M_i = B - P_i
For each option, multiply listed cash cost by one plus its contingency rate, add coordination hours multiplied by the user’s hour value, and subtract that protected total from the common budget.
DEEPER DECISION ANALYSIS
Decisions the lower number cannot make
Consent comes before spectacle
A cost comparison cannot determine whether a proposal is wanted, whether the timing is welcome, or whether public attention is comfortable.
Scope discipline prevents false savings
If option A includes travel and photography while option B omits them, the apparent comparison is a bookkeeping difference rather than a plan advantage.
Time value is a sensitivity input
Recalculate with zero, a moderate value, and a high value to see whether the preferred plan changes because of coordination burden.
WORKED DECISION CASES
Two genuinely different proposal choices
Private weekend plan
A quieter plan may have higher lodging cost but fewer coordination hours and a smaller contingency because fewer vendors must be synchronized.
Large surprise gathering
A guest-heavy plan may start with a lower venue quote yet require more communication, backup arrangements, accessibility checks, and privacy judgment.
TECHNICAL LANGUAGE
Proposal planning terms
- Protected cost
- Cash plan plus reserve plus the selected value of coordination time.
- Cost boundary
- The rule defining which items appear in both alternatives.
- Contingency
- A reserve percentage applied to listed cash cost.
- Coordination hour
- An hour of active planning effort included by the user.
- Budget margin
- Remaining protected budget after one plan is priced.
- Sensitivity check
- Recalculation with another assumption to see whether the decision changes.
EVIDENCE AND DATA LINEAGE
Price each option from dated records
Use current vendor quotes, travel searches, written cancellation terms, a complete task list, and a dated budget. Record what is excluded. The Consumer.gov budget method supports listing expenses before subtracting them from available income, while the hour-value policy remains entirely yours.
LIMITS AND EXCLUSIONS
What protected-cost arithmetic cannot capture
- The model does not predict acceptance, relationship readiness, or emotional impact.
- Contingency is applied to listed cash cost only and does not model correlated price shocks.
- The hour value is a subjective comparison device rather than wages owed or market value.
- Taxes, tips, cancellation losses, and currency conversion appear only if included in base cost.
- A lower protected cost is not a recommendation to ignore consent, privacy, accessibility, or safety.

FREQUENTLY ASKED QUESTIONS
Questions about comparing proposal plans
Should the engagement ring be included?
Include it in both plans if the current decision covers ring spending; otherwise exclude it from both and document that boundary.
What if I do not want to value my time?
Enter zero for planning-hour value. The page will then compare protected cash costs while still showing coordination hours in the ledger.
Is the cheaper plan automatically better?
No. The result answers a bounded cost question and says nothing about welcome timing, privacy preferences, or the quality of the relationship.
How should I choose contingency percentages?
Use quote volatility, cancellation exposure, and known omissions for each plan; do not copy one percentage merely to make the plans look symmetrical.
Why can a margin be negative?
A negative margin deliberately shows how far a protected plan exceeds the entered budget. The calculator does not silently cap the plan.
Can this compare more than two proposals?
Not directly. Compare a stable reference option against each additional plan while keeping the budget and cost boundary unchanged.
How do I treat refundable deposits?
Include the cash outflow when it must be funded, then document the refund condition separately. Do not subtract a hoped-for refund from protected cost before the contract makes it reasonably recoverable.
What if one plan has a much longer lead time?
The model values active coordination hours but does not price calendar delay. Record lead time as a separate feasibility constraint and reject any option that cannot be executed without rushed or unreliable assumptions.
Can I compare a surprise plan with a jointly planned proposal?
Only for logistics. The comparison cannot value consent or preference, so first confirm that the format itself is welcome; a lower protected cost never justifies unwanted surprise or public pressure.
When should I stop relying on this result?
Stop when the two plans use different scopes, prices are stale, the budget excludes essential obligations, or consent, safety, accessibility, or legal questions dominate the decision.
IMPORTANT NOTE
A proposal plan must remain voluntary and personal
Use this worksheet only for logistics and budget reflection. It cannot assess relationship readiness, replace direct conversations about marriage, or justify pressure, surveillance, deception that creates risk, or unwanted public attention.
