How this calculator works
New rent = current rent × (1 + increase). Extra per month is the difference; extra per year multiplies that by 12. The multi-year figure compounds the same increase: current rent × (1 + increase)^years.
Assumes the same percentage increase each year, which real increases won't perfectly follow. Use it to see the trajectory and pressure-test your budget, not to predict an exact future rent.
What this assumes
- The increase you enter, applied to the current rent. Local rent control may cap it, and this does not check.
- It compares staying against the cost of moving only if you enter moving costs.
- It assumes the increase is real rather than an opening negotiating position.
What changes this number
- Cost of moving
- Deposit, removals and time off. Frequently more than a year of the increase, which is why small rises are usually worth accepting.
- Market rent nearby
- The only way to judge whether the increase is fair, and the strongest negotiating input.
- Compounding
- Successive annual increases apply to the raised rent, so a run of small rises adds up faster than expected.

Frequently asked questions
How do I calculate a rent increase?
Multiply your current rent by the increase percentage to get the dollar increase, then add it. A 5% increase on $2,000 rent is $2,000 × 0.05 = $100 more, for $2,100 a month — an extra $1,200 over the year. This calculator also compounds the increase over several years.
How much can a landlord raise rent?
It depends on where you live. Many areas have no cap for market-rate units, so increases are limited only by the market and your lease terms, while rent-controlled or rent-stabilized units and some states cap annual increases. Landlords generally must give written notice (often 30–60 days) — check your local laws.
Why does a small percentage matter so much?
Because rent is a large recurring cost and increases compound. A 5% raise every year nearly doubles rent over 15 years. Over a few years, steadily rising rent is a major reason many people compare renting to buying, where a fixed-rate mortgage payment stays flat.
What can I do about a rent increase?
Negotiate — a good tenant who pays on time has value, and landlords weigh vacancy costs. You can propose a smaller increase, a longer lease at a lower rate, or improvements in exchange. Comparing your increased rent against local market rates and the cost of moving strengthens your position.
