What this calculator does
Compare renovation funding options with monthly payment, total interest, and value-based break-even estimate.
How it's calculated
- Inputs are validated before running the calculator-specific compute() function.
- Core math is deterministic and implemented in src/lib/calculators/renovation-loan.ts.
- Results are recalculated instantly as values change and are shareable via query parameters.
- Disclosure assumptions and limitations are shown on-page for decision context.
Example
Example scenario: Project cost = 45000 USD; Financing type = Personal loan; APR = 8.5 %; Term = 7 years. Sample output: Estimated monthly payment: $712.64
Common mistakes
- Using optimistic rates or appreciation assumptions without testing a conservative case.
- Ignoring taxes, insurance, HOA, or maintenance in monthly cost planning.
- Treating modeled outputs as guaranteed quotes rather than planning estimates.
- Not comparing at least two scenarios before making a financing decision.
- Skipping professional review for legal, tax, underwriting, or insurance details.
FAQs
Why is cash monthly payment zero?
Cash avoids loan payments and interest, but it still has opportunity cost and liquidity tradeoffs.
Does this include tax effects?
No. It does not model tax deductions, credits, or household-specific tax outcomes.
Is expected value increase guaranteed?
No. Renovation resale value depends on market demand, scope quality, and timing.
How should I compare financing types?
Compare payment pressure, total interest, and liquidity impact alongside expected project benefit.
Can this replace contractor and appraisal review?
No. Use licensed contractor bids and professional valuation for final decisions.
