Future rent projection.

Rent increase calculator projects future rent given annual percentage increase. 1,500/month at 5% annual increase = 1,575 next year, 1,914 in 5 years (28% total increase). Useful for tenants planning long-term housing costs and landlords planning rent reviews.

1,500 current monthly rent × 5% annual increase × 5 years = 1,914 monthly. 414 monthly increase, 4,968 annual additional cost. Compounding makes 'small' annual increases significant over time. typical rent inflation 5-8% recent years - tenants face significant cost increases over multi-year tenancies.

Rent increase rules: assured shorthold tenancies (most common) - usually fixed during initial term, then renewable with notice. Section 13 notice for statutory increases. Council/housing association: rent increase formulas (CPI + 1% common). Private market: whatever market bears, but tenant can negotiate or move. Most rent increases pegged to CPI + 1-2% in well-regulated markets.

Quick example

With current monthly rent of 1,500 and annual increase of 5% (plus years of 5 years), the result is 1,914.42. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Current Monthly Rent, Annual Increase %, and Years. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Future rent = current × (1 + increase %)^years. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Using this well

Treat the output as one point on a wider map. Run it three times — a pessimistic case, a central case, and a stretch case — and plan against the pessimistic one. That habit alone separates people who stick with an investment plan from those who bail at the first wobble.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.
