Compare Rent vs buy scenarios

Change one input, hold everything else identical, and see how much that one input is actually worth. The gap between the scenarios is the whole answer.

What to compare

Everything else below is held identical across the scenarios, so the only thing separating the lines is this one input.

Shared by every scenario

The rest is borrowed. If you rent instead, this is the money you invest.

Per year, and it can be negative. This is the assumption the answer is most sensitive to.

What the down payment and any monthly saving earn if you rent instead of buying.

A percentage of the property price each year. Costs an owner carries and a tenant does not.

Moving how long you stay from 10 years to 30 years changes buying, against renting by −₹2,68,42,735. Every other input was identical in both.

Show how each scenario is calculated

Scenario A — 10 years

Both paths are simulated month by month over the horizon: the loan amortises while the property appreciates, and in parallel the renter pays a rising rent and invests the down payment plus any month where the owner pays more. What is compared at the end is net worth, not monthly outgo.

  1. Down payment

    ₹1,00,00,000 × 20%

    = ₹20,00,000

    If you rent instead, this is the money that gets invested.

  2. Borrowed

    ₹1,00,00,000 − ₹20,00,000

    = ₹80,00,000

  3. Monthly EMI on that loan

    over 10 years

    = ₹99,189

  4. Monthly ownership costs

    ₹1,00,00,000 × 1% ÷ 12

    = ₹8,333

    Maintenance, property tax and insurance — paid by an owner, not by a tenant.

  5. Worth after 10 years if you buy

    property value at the horizon, less the loan still outstanding

    = ₹1,79,08,477

  6. Worth after 10 years if you rent and invest

    the down payment and every monthly saving, compounded

    = ₹1,94,17,398

  7. Buying, against renting

    ₹1,79,08,477 − ₹1,94,17,398

    = -₹15,08,921

    Buying does not get ahead within this horizon, at these assumptions.

Scenario B — 20 years

Both paths are simulated month by month over the horizon: the loan amortises while the property appreciates, and in parallel the renter pays a rising rent and invests the down payment plus any month where the owner pays more. What is compared at the end is net worth, not monthly outgo.

  1. Down payment

    ₹1,00,00,000 × 20%

    = ₹20,00,000

    If you rent instead, this is the money that gets invested.

  2. Borrowed

    ₹1,00,00,000 − ₹20,00,000

    = ₹80,00,000

  3. Monthly EMI on that loan

    over 20 years

    = ₹69,426

  4. Monthly ownership costs

    ₹1,00,00,000 × 1% ÷ 12

    = ₹8,333

    Maintenance, property tax and insurance — paid by an owner, not by a tenant.

  5. Worth after 20 years if you buy

    property value at the horizon, less the loan still outstanding

    = ₹3,20,71,355

  6. Worth after 20 years if you rent and invest

    the down payment and every monthly saving, compounded

    = ₹3,86,50,648

  7. Buying, against renting

    ₹3,20,71,355 − ₹3,86,50,648

    = -₹65,79,293

    Buying does not get ahead within this horizon, at these assumptions.

Scenario C — 30 years

Both paths are simulated month by month over the horizon: the loan amortises while the property appreciates, and in parallel the renter pays a rising rent and invests the down payment plus any month where the owner pays more. What is compared at the end is net worth, not monthly outgo.

  1. Down payment

    ₹1,00,00,000 × 20%

    = ₹20,00,000

    If you rent instead, this is the money that gets invested.

  2. Borrowed

    ₹1,00,00,000 − ₹20,00,000

    = ₹80,00,000

  3. Monthly EMI on that loan

    over 30 years

    = ₹61,513

  4. Monthly ownership costs

    ₹1,00,00,000 × 1% ÷ 12

    = ₹8,333

    Maintenance, property tax and insurance — paid by an owner, not by a tenant.

  5. Worth after 30 years if you buy

    property value at the horizon, less the loan still outstanding

    = ₹5,74,34,912

  6. Worth after 30 years if you rent and invest

    the down payment and every monthly saving, compounded

    = ₹8,57,86,568

  7. Buying, against renting

    ₹5,74,34,912 − ₹8,57,86,568

    = -₹2,83,51,656

    Buying does not get ahead within this horizon, at these assumptions.

Every scenario is computed by the same engine the buying, against renting calculator uses, so the last line of each is the figure in the table above. Intermediate values are shown rounded for reading; the calculation carries full precision throughout.

Over time

Each line is one scenario. Because every other input is identical, the gap between them is the effect of how long you stay alone.

How to read this

  • Only one input differs. Every other value is identical across the scenarios, which is what makes the gap between them readable. If each scenario had its own assumed return, the chart would be comparing guesses rather than choices.
  • A bigger number is not automatically better. On a loan comparison the larger figure is the worse one, and on any of these the right answer depends on circumstances this page knows nothing about.
  • The rate is still an assumption. Comparing scenarios does not make any of them a forecast — it only shows how sensitive the outcome is to the input you changed.
