Real Estate Buying Planner

Estimate the inflated cost of your target down payment and create a savings strategy.

Formula & Mathematical Approach

Estimates the required down payment for a future home purchase and calculates the monthly savings rate.

Future House Cost=Current Cost×(1+Property Inflation100)Years\text{Future House Cost} = \text{Current Cost} \times \left(1 + \frac{\text{Property Inflation}}{100}\right)^{\text{Years}}
Target Down Payment=Future House Cost×Down Payment %100\text{Target Down Payment} = \text{Future House Cost} \times \frac{\text{Down Payment \%}}{100}
Required Monthly SIP=Target Down Payment[(1+i)Months1i]×(1+i)\text{Required Monthly SIP} = \frac{\text{Target Down Payment}}{\left[ \frac{(1 + i)^{\text{Months}} - 1}{i} \right] \times (1 + i)}
Show Plain Text / Excel Formula
Future House Cost = Current Cost * (1 + Property Inflation / 100) ^ Years
Target Down Payment = Future House Cost * (Down Payment % / 100)
Required SIP = Target Down Payment / (SIP Compounding Factor)

Key Assumptions

  • Property values rise steadily with property-specific inflation.
  • Down payment percentage remains constant.
  • Level monthly savings are made.
