What this means

The figure is the sticker price your budget supports for the vehicle itself. Taxes, registration, insurance and running costs are extra, so keep some headroom.

3 Important insights
  • Inflation often matters more than expected over the long run.
  • Small rate changes can significantly affect total outcomes.
  • Long-term consistency usually beats short-term timing.

Small, consistent changes compound: time in the market usually beats timing the market.

How it works

Max loan = M × (1 − (1 + i)−n) ÷ i, then Max price = Max loan + Down payment. M = monthly budget, i = APR ÷ 12, n = term in months.

Example

$400/month at 7% APR over 60 months with $3,000 down → about a $23,200 car.

Frequently asked questions

How much of my income should a car payment be?+

A common guideline keeps the car payment under about 10-15% of monthly take-home pay, and total car costs (payment, insurance, fuel, upkeep) under roughly 20%.

Does this include tax, insurance and fees?+

No — it estimates the vehicle price your payment and down payment support. Budget separately for sales tax, registration, insurance and running costs.

Quick answers

Short, sourced answers to the questions people (and AI assistants) ask most.

What is Car Affordability?
A car affordability calculator works out the vehicle price you can afford from the monthly payment you are comfortable with, the loan's APR and term, and your down payment.
Why does Car Affordability matter?
The figure is the sticker price your budget supports for the vehicle itself. Taxes, registration, insurance and running costs are extra, so keep some headroom.
How is Car Affordability calculated?
It reverses the loan formula: from a monthly payment it finds the largest loan that payment supports over the term at the given rate, then adds your down payment to get the car price. Formula: Max loan = M x (1 - (1 + i)^-n) / i; Max price = Max loan + down payment (M = monthly payment, i = APR/12, n = months).
What is a good car affordability?
A common guideline keeps the car payment under about 10-15% of monthly take-home pay, and all car costs under roughly 20%. Longer terms lower the payment but raise total interest.
What are common car affordability mistakes?
Stretching the term to afford a pricier car - it cuts the payment but you pay much more interest.
When should you use the Car Affordability Calculator?
Use it before shopping to set a realistic price ceiling, or to see how a bigger down payment or longer term changes what you can afford.

What is the Car Affordability Calculator?

A car affordability calculator works out the vehicle price you can afford from the monthly payment you are comfortable with, the loan's APR and term, and your down payment.

How the Car Affordability Calculator works

It reverses the loan formula: from a monthly payment it finds the largest loan that payment supports over the term at the given rate, then adds your down payment to get the car price.

Max loan = M x (1 - (1 + i)^-n) / i; Max price = Max loan + down payment (M = monthly payment, i = APR/12, n = months)

What's a typical value?

A common guideline keeps the car payment under about 10-15% of monthly take-home pay, and all car costs under roughly 20%. Longer terms lower the payment but raise total interest.

Worked example

$400/month at 7% APR over 60 months with $3,000 down supports about a $23,200 car (roughly a $20,200 loan plus the down payment).

Common mistakes to avoid

  • Stretching the term to afford a pricier car - it cuts the payment but you pay much more interest.
  • Forgetting tax, insurance and maintenance on top of the payment.
  • Ignoring depreciation and the risk of owing more than the car is worth.
