About this calculator
Repainting is cheaper per event but needs redoing every 7-10 years, while re-siding costs far more upfront but can last 30-40 years with minimal upkeep. This tool annualizes both paths over a long horizon so you can compare true cost per year of ownership rather than just the sticker price of the next paint job.
Worked example
Using the values the calculator loads with:
Inputs
- Cost per repaint: 6500 $
- Years between repaints: 8
- Cost to re-side: 22000 $
- Siding lifespan: 35 yrs
- Siding annual upkeep: 100 $
- Comparison horizon: 35 yrs
Results
- Lower total cost over horizon: Re-Side
- Repaint path total cost: $32,500
- Re-siding path total cost: $25,500
- Difference: $7,000

FAQ
Does re-siding add resale value?
Yes — new siding is one of the higher ROI exterior projects, often recouping 70-80% of cost at resale, which this calculator doesn't credit but should tilt the decision further toward siding for longer holds.
Is paint quality a factor?
A lot — premium paint and proper prep can push a repaint cycle from 7 years to 12+, meaningfully changing the annualized cost, so use your actual expected cycle length.
What about wood siding needing repainting anyway?
This comparison assumes re-siding with a low-maintenance material like vinyl or fiber cement; wood siding would still need periodic painting even after replacement.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
