Due Diligence Budget Calculator
DD costs for acquisition include physical, environmental, financial, and legal reviews.
Total DD budget
$124,500
Hard costs subtotal
$39,500
Soft costs subtotal
$85,000
How the math works
Total = sum of all DD components. Hard costs (physical) + soft costs (legal/financial).
$12k env + $9k PCA + $45k legal + $25k fin + $6.5k survey + $12k appraisal + $15k other = $124.5k total DD.

How this calculator works
What this page estimates
This Due Diligence Budget Calculator is built to give a quick, browser-based estimate for due diligence budget. DD costs for acquisition include physical, environmental, financial, and legal reviews. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the due diligence budget result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this due diligence budget estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions
Typical DD costs?
$10M property: $35-75k total DD. $50M property: $100-200k. $200M+ property: $300-800k. Cost scales with complexity, not linearly with size. Triple-net portfolios simpler; ground-up development more complex.
DD components?
Phase I environmental: $3-8k. Phase II (if needed): $15-75k. Property Condition Assessment: $5-15k. Legal review: $20-100k. Financial audit: $15-40k. Survey: $2-10k. Appraisal: $5-15k. Title: $5-25k. Other: $5-25k.
Budget allocation?
Retail/multifamily: environmental light, CapEx heavy. Industrial: environmental heavy, legal moderate. Office: legal heavy (tenants), structural moderate. Hotel: complex — financial audit + PIP + franchise review. Budget by asset type.
How often should I rerun this?
Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
