Frequently asked questions

What does the Rent increase calculator actually compute?

It takes Current monthly rent and Increase (%) and derives New monthly rent and Increase amount from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

2 values: Current monthly rent ($) and Increase (%). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Current monthly rent = $1,000.00 and Increase (%) = 3, the calculator returns New monthly rent = $1,030.00 and Increase amount = $30.00. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Current monthly rent = $2,000.00 and Increase (%) = 6 instead, New monthly rent goes from $1,030.00 to $2,120.00 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Current monthly rent = $500.00 and Increase (%) = 1.5, New monthly rent comes out at $507.50. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Setting or checking a rent, working out the yield a property really returns, and splitting a part-month at the start or end of a tenancy.

What is the most common mistake?

Quoting a gross yield. Once charges, tax, insurance, management and vacancy are taken out, the net figure is routinely a third to a half lower.

What is the difference between the Rent increase calculator and the Maximum rent calculator?

This one returns New monthly rent and Increase amount; the Maximum rent calculator returns Maximum rent, charges excluded and Housing budget at that rate. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Rent-to-income ratio calculator is the closest one after this: Compute the share of your income that goes to rent (the 30% rule of thumb).

What else is worth having open alongside it?

Rent vs Buy Calculator and Section 8 rent calculator — they come up in the same task often enough to be worth a second tab.

ExplainerWhat a Rent Increase Is Allowed to BeFive of six markets index the permitted increase to a published statistic, and each names a different one.

The rule is a fixed percentage applied to a budget whose other needs are not proportional to income — which is exactly why housing policy uses residual income instead.ExplainerVacancy Is Not a Percentage You Lose — It Is a Month You Do Not CollectSix weeks empty is 11.11 percent vacancy on a one-year tenancy and 4.00 percent on a three-year one. The break-even rent increase that justifies risking that void is 29.52 percent over a year and 8.99 percent over three.ExplainerThe Most Rent You Should Agree ToThree different numbers decide a letting: the rent the agent screens, the total occupancy cost your budget has to survive, and the cash due at signing.

Floor area is better and still leaves someone envious. The sealed-bid envy-free split gives $850, $700 and $850 — and nobody wants to swap.
