Renovation Quote-to-Close Calculator.
Weighted revenue per quote and won revenue per month — the two numbers ID firms actually plan against.
By shakalakaa · 18 Aug 2026
Quick answer: Weighted revenue per quote = average quote value × close rate. A firm issuing 20 quotes/month at RM60,000 average and 15% close rate is doing RM180,000 in won revenue per month, weighted at RM9,000 per quote. Cycle length in weeks tells you when today's quotes turn into cash — a 12-week cycle lags quote flow by 3 months.
FAQ
Why does cost per lead tell an ID firm almost nothing on its own?
ID firms quote far more than they close and the cycle is months long. A cheap lead that never converts is worthless; an expensive lead that closes a RM250k project is a bargain. Weighted revenue per quote — average value × close rate — is the figure that actually maps to cash.
What does cycle length change in the output?
Cycle length in weeks converts quote-flow into a realistic monthly revenue view. A 12-week cycle means quotes issued today convert to revenue two to three months later, so month-on-month cash lags quote volume by that cycle.
What inputs should I use?
Your own last-90-days figures — real quotes issued per month, average quote value, real close rate from your CRM, and the actual weeks between quote and signed contract. No industry defaults.
