Rent growth calculator
Compound Rent Increase Calculator
Model repeated annual rent increases and see the rent by year.
Estimated new rent
This estimates the math impact. Lease terms and local rules can change whether an increase is allowed.
| Year | Monthly rent | Annual rent |
| 0 | $2,000.00 | $24,000.00 |
| 1 | $2,080.00 | $24,960.00 |
| 2 | $2,163.20 | $25,958.40 |
| 3 | $2,249.73 | $26,996.76 |
| 4 | $2,339.72 | $28,076.64 |
| 5 | $2,433.31 | $29,199.72 |
How this calculator works
The calculator applies the entered percentage repeatedly for the number of years entered. It shows the new monthly rent, monthly change, annual rent before, and annual rent after so the increase is visible beyond one payment.
When to use this page
Use it to check renewal offers, rent notices, budget changes, CPI-linked clauses, scheduled increases, or before-and-after rent math before you decide whether to move, negotiate, or ask for clarification.
What this result does not include
This is arithmetic only. It does not decide whether a rent increase is allowed, whether notice is valid, whether a unit is exempt, whether local caps apply, or whether fees and utilities can change separately.
- Check whether the amount is a fixed increase, percentage increase, CPI-linked increase, or scheduled escalation.
- Confirm whether the rent amount excludes separate fees, utilities, parking, or service charges.
- For regional pages, verify current official rules before using the result in a dispute or notice response.
How to read the result
The monthly change shows the immediate payment impact. The annual before-and-after amounts show the full-year impact, which is usually the better number for deciding whether a renewal offer, CPI adjustment, or escalation clause fits your budget. If rent is paid weekly, fortnightly, or every 4 weeks, convert the new monthly rent before comparing payment-cycle cash flow.
Before acting on an increase
Use the calculator to check the arithmetic, then compare the result with the lease clause or rent notice. A correct percentage calculation does not prove that the increase is permitted or that every required notice step was followed.
Worked examples
Multi-year renewal planning
A repeated 4% increase compounds, so the fifth-year rent is higher than applying one flat increase to the starting rent.
Annual budget view
Use the yearly rows to compare staying put with moving costs, not just the next monthly payment.
